Siluria Technologies unveils new development unit for liquid fuels from natural gas based on OCM and ETL technologies

March 21, 2014

Siluria Technologies, the developer of novel bio-templated catalysts for the economic direct conversion of methane (CH4) to ethylene (C2H4) (earlier post), unveiled a development unit for producing liquid fuels from natural gas based on Siluria’s proprietary oxidative coupling of methane (OCM) and ethylene-to-liquid (ETL) technologies.

Together, Siluria’s OCM and ETL technologies form a unique and efficient process for transforming methane into gasoline, diesel, jet fuel and other liquid fuels. Unlike the high-temperature, high-pressure cracking processes employed today to produce fuels and chemicals, Siluria’s process employs catalytic processes to create longer-chain, higher-value materials, thereby significantly reducing operating costs and capital.

Researchers develop new lower-temperature process for conversion of natural gas alkanes to alcohols

March 14, 2014

Researchers from The Scripps Research Institute (TSRI) and Brigham Young University have devised a new and more efficient method to convert natural gas into liquid products at much lower temperatures than conventional methods.

Their work, reported in the journal Science, uses main-group metals such as thallium and lead to oxidize methane and the other alkanes contained in natural gas (ethane and propane) to liquid alcohols at about 180 °C instead of the more than 500 °C used in current processes, said SRI Professor Roy Periana, who led the research. This creates the potential to produce fuels and chemicals at much lower cost.

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.

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.

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.
