Shell producing base oil from natural gas for motor oils
March 08, 2014
Shell announced the production of the first clear base oil—the main component of motor oils—made from natural gas using its gas-to-liquids (GTL) PurePlus Technology. Shell PurePlus Technology is now being used to create motor oils for motorists in the United States. Pennzoil Platinum and Pennzoil Ultra Platinum Full Synthetic motor oils are the only ones blended exclusively with these GTL base oils.
Shell PurePlus Technology base oil is manufactured at the Pearl GTL facility in Ras Laffan in Qatar, a partnership between Qatar Petroleum and Shell. Shell PurePlus base oil is clear due to having fewer of the impurities found in crude oil. The Shell GTL and the Shell PurePlus base oil manufacturing processes have been the subject of multiple patents.
Primus Green Energy’s STG+ patent for liquid fuel synthesis from syngas approved
February 05, 2014
Primus Green Energy Inc., an alternative fuel company that converts natural gas and other feedstocks directly into drop-in transportation fuels and solvents (earlier post), announced that its patent application covering its STG+ liquid fuel synthesis technology has been allowed by the US Patent and Trademark Office (USPTO). STG+ produces high-quality, cost-effective, drop-in liquid transportation fuels directly from syngas derived from natural gas and other carbon-rich feedstocks in a single-loop process.
STG+ essentially improves upon commercial methanol synthesis processes and ExxonMobil’s methanol-to-gasoline (MTG) process, combining them into an integrated, optimized system that efficiently converts syngas directly to fuels. In addition to the gasoline product, the STG+ process can also produce jet fuel, diesel and high-value chemicals by changing the catalysts and operating conditions. The company, which is currently producing synthetic gasoline at its demonstration plant (earlier post), plans to build several more reactors in parallel to the current production train for other fuel products.
Sasol, GE develop new anaerobic microbial technology for cleaning of Fischer-Tropsch waste water; boosting gas-to-liquids (GTL) value proposition
November 06, 2013
Sasol and General Electric (GE: NYSE)’s GE Power & Water have together developed new technology that will clean waste water from Fischer-Tropsch plants used to produce synthetic fuels and chemicals, while also providing biogas as a by-product for power generation. The new Anaerobic Membrane Bioreactor Technology (AnMBR) will be further developed at a new demonstration plant at Sasol’s R&D Campus at its Sasol One Site in Sasolburg, South Africa.
AnMBR involves anaerobic micro-organisms that are able to live in environments devoid of oxygen, such as sediment layers on floors of lakes, dams and the ocean. Sasol currently uses aerobic microbes to treat GTL and coal-to-liquids (CTL) effluents in ORYX GTL, Qatar and Synfuels, Secunda facilities.
Pinto Energy to build 2,800 bpd small-scale GTL plant in Ashtabula; Velocys microchannel technology
September 23, 2013
Pinto Energy LLC (Pinto), a developer of smaller scale Gas-to-Liquids (GTL) facilities, will build a 2,800 barrel per day (bpd) GTL plant at Pinto’s 80-acre industrial site to the east of Ashtabula, Ohio. The plant will convert abundant low-cost natural gas from the Utica and Marcellus shale region into high-value specialty products (solvents, lubricants and waxes), as well as transportation fuels.
Pinto has chosen to utilize Velocys Plc (Velocys) Fischer-Tropsch microchannel reactor technology. (Velocys is part of the Oxford Catalysts Group plc; Oxford Catalysts is changing its name to Velocys plc on 25 September 2013.) Velocys advanced catalysts and proprietary microchannel reactors offer unparalleled efficiencies for GTL projects today, Pinto said. The company has agreed to commercial license terms with Velocys and made a down payment towards the FT reactors.
ARPA-E awarding $3.5M to Berkeley Lab project to develop novel enzymatic gas-to-liquids pathway
September 22, 2013
On 19 September, the Advanced Research Project Agency-Energy (ARPA-E) awarded $34 million to 15 projects to find advanced biocatalyst technologies that can convert natural gas to liquid fuel for transportation. (Earlier post.) The largest award in the technical area of High-Efficiency Biological Methane Activation in the new program, (Reducing Emissions using Methanotrophic Organisms for Transportation Energy—REMOTE, earlier post), provides $3.5 million to a team led by Dr. Christer Jansson at Lawrence Berkeley National Laboratory (LBNL) to work on a novel methylation process to convert natural gas to liquid transportation fuels.
The project, called “Enzyme Engineering for Direct Methane Conversion,” involves designing a novel enzyme—a PEP methyltransferase (PEPMase)—by engineering an existing enzyme to accept methane instead of carbon dioxide. This methylation process, which does not exist in nature, will be used as the basis for the gas-to-liquids pathway.
ARPA-E selects 33 projects for $66M in awards; advanced biocatalysts for gas-to-liquids and lightweight metals
September 19, 2013
The US Advanced Research Projects Agency-Energy (ARPA-E) is awarding around $66 million to 33 projects under two new programs. One program, Reducing Emissions using Methanotrophic Organisms for Transportation Energy (REMOTE, earlier post), provides $34 million to 15 projects to find advanced biocatalyst technologies that can convert natural gas to liquid fuel for transportation.
The other program, Modern Electro/Thermochemical Advancements for Light-metal Systems (METALS, earlier post), provides $32 million to 18 projects to find cost-effective and energy-efficient manufacturing techniques to process and recycle metals for lightweight vehicles. The funding opportunity announcements for both programs were released earlier this year in March.

The US Energy Information Administration’s (EIA’s) International Energy Outlook 2013 (IEO2013) projects that world energy consumption will grow by 56% between 2010 and 2040, from 524 quadrillion British thermal units (Btu) to 820 quadrillion Btu. Most of this growth will come from non-OECD (non-Organization for Economic Cooperation and Development) countries, where demand is driven by strong population and economic growth; energy intensity improvements moderate this trend
Renewable energy and nuclear power are the world’s fastest-growing energy sources, each increasing 2.5% per year, according to the biennial report. However, fossil fuels continue to supply nearly 80% of world energy use through 2040. Natural gas is the fastest-growing fossil fuel, as global supplies of tight gas, shale gas, and coalbed methane increase. Given current policies and regulations limiting fossil fuel use, worldwide energy-related CO2 emissions rise from about 31 billion metric tons in 2010 to 36 billion metric tons in 2020 and then to 45 billion metric tons in 2040, a 46% increase over the 30-year span.
Fulcrum BioEnergy demonstrates integrated process to convert MSW to jet and diesel; $4.7M DoD grant to begin plant engineering
May 28, 2013
Fulcrum BioEnergy, Inc. has successfully demonstrated the conversion of municipal solid waste (MSW)—household garbage—into jet and diesel fuels. Fulcrum says its ability to produce drop-in fuels from MSW opens up an 80 billion gallon per year fuel market and expands its customer base for its national development program.
This demonstrated process adds fuel diversity to Fulcrum’s products and complements its previously demonstrated MSW-to-ethanol process. For that process, Fulcrum uses a two-stage thermochemical process involving gasification of municipal solid waste (MSW) followed by the catalytic conversion of the syngas to ethanol. (Earlier post.)

March 28, 2013
|Schematic diagram of the Primus STG+ process. Click to enlarge.|
Primus Green Energy Inc., developer of a proprietary process to produce gasoline and other fuels from biomass and/or natural gas (earlier post), will provide financial support to engineers at Princeton University for general research on synthetic fuels, which will include assessments of various gas-to-liquids (GTL) technologies—including Primus’ own STG+—for sustainability and economic viability.
STG+ technology converts syngas into drop-in high-octane gasoline and jet fuel with a conversion efficiency of ~35% by mass of syngas into liquid transportation fuels (the highest documented conversion efficiency in the industry) or greater than 70% by mass of natural gas. The fuels produced from the Primus STG+ technology are very low in sulfur and benzene compared to fuels produced from petroleum, and they can be used directly in vehicle engines as a component of standard fuel formulas and transported via the existing fuel delivery infrastructure.
ARPA-E to award up to $20M to projects for bioconversion of methane to liquid fuels; seeking <$2/gge and ability to meet US demand for transportation fuels
March 17, 2013
The US Department of Energy’s (DOE’s) Advanced Research Projects Agency - Energy (ARPA-E) has issued a Funding Opportunity Announcement (DE-FOA-0000881) for up to $20 million to fund the development of bioconversion technologies to convert methane into liquid fuels. (Earlier post.) This program envisions the development of transformative bioconversion technologies that are capable of producing liquid fuels economically from natural gas at less than $2 per gallon of gasoline equivalent and at levels sufficient to meet US demand for transportation fuels.
Of interest for the Reducing Emissions Using Methanotrophic Organisms For Transportation Energy (REMOTE) program are biological routes to improve the rates and energy efficiencies of methane activation and subsequent fuel synthesis, as well as approaches to engineer high-productivity methane conversion processes. REMOTE considers three technical categories:
