China researchers devise process to convert biomass to gasoline via one-step DME synthesis: DTG

October 10, 2016

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology have proposed a new process for the conversion of biomass to gasoline via a one-step DME synthesis (DTG: Dimethyl ether to gasoline). In a paper in the journal Fuel, they report a per-pass conversion of CO and the production capacity of gasoline of up to 45% and 4.4 kg/h, respectively.

Their homemade catalysts exhibited favorable activity, selectivity and stability during all the operations. The gasoline obtained from the pilot plant had a high octane number (RON>93). Although further studies are needed on mass and energy balances to ensure the most economical and optimal heat integration strategy, the practical experience of this work is sufficiently promising to merit further investigations, the team suggested.

Cummins Euro 6 engines compatibile with HVO renewable diesel & other paraffinic fuels; fuels at “point of commercial maturity”

September 22, 2016

Cummins Inc. announced Euro 6 (VI) engine compatibility for use with Hydrotreated Vegetable Oil (HVO) renewable diesel and other EN 15940 paraffinic fuels, representing a significant step forward to reduce the carbon footprint of Cummins-powered bus, truck and coach fleets operating in Europe.

Compared with conventional fossil-based diesel, HVO offers the potential to reduce greenhouse gas (GHG) emissions by 40 to 90 percent over the total life cycle of the fuel, dependent on the level of sustainable feedstock used in the production process.

Governments of Canada & Québec award $76.5M to AE Côte-Nord Canada Bioenergy for renewable fuel oil from forest residues w/ Ensyn RTP

July 14, 2016

The Governments of Canada and Québec will provide $76.5 million in funding to AE Côte-Nord Canada Bioenergy Inc. for the production of renewable fuel oil (RFO) from forest residues. The plant, which will use Ensyn’s RTP (rapid thermal processing) (earlier post), will be the first commercial RTP facility designed and optimized for the production of biocrude used for heating, cooling and refinery applications, according to Dr. Robert Graham, Chairman, Ensyn Corporation.

The Port-Cartier plant will also be the first commercial-scale facility of this kind in Québec. The goal of the project is to convert forest residues into 40 million liters (10.6 million gallons US) of renewable fuel oil per year. When upgraded into transportation fuels, this will remove up to 70,000 tonnes of CO2-equivalent emissions per year. Production of renewable fuel oil is set to begin in 2017.

New 3-step process for conversion of kraft lignin from black liquor into green diesel

June 01, 2016

Researchers in Sweden and Spain have devised a three-step process for the conversion of precipitated kraft lignin from black liquor into green diesel. Their paper appears in the journal ChemSusChem.

The kraft process converts wood into wood pulp for paper production. The process produces a toxic byproduct referred to as black liquor—a primarily liquid mixture of pulping residues (such as lignin and hemicellulose) and inorganic chemicals from the Kraft process (sodium hydroxide and sodium sulfide, for example). For every ton of pulp produced, the kraft pulping process produces about 10 tons of weak black liquor or about 1.5 tons of black liquor dry solids.

Altex & Unitel partner to demonstrate a new technology for making synthetic gasoline from biomass

April 05, 2016

Altex Technologies has selected Unitel to provide engineering services to design and build a pilot system that will produce 1 BPD of synthetic gasoline from biomass (Biomass Conversion to Synthetic Gasoline System, BCSGS). This project is funded by a ~$1-million grant from the California Energy Commission under the auspices of its Alternative and Renewable Fuels and Vehicle Testing Program.

The Altex process does not require the intermediate conversion of the feedstock into synthesis gas or pyrolysis liquids, plus it does not require hydrogen. Some of the feedstocks that Altex plans to use include alfalfa, corn stover, switchgrass, and processed woodchips.

China’s Kaidi to build €1B BTL biofuel refinery in Finland

February 13, 2016

China-based Kaidi plans to build a €1-billion (US$1.1-billion) biofuel refinery in Kemi. The planned refinery will produce 200,000 tons of biofuels per year, of which 75% will be biodiesel and 25% biogasoline.

The second-generation biomass plant will use energy wood as the main feedstock and it will be the first of its kind, not only in Finland but globally. Kaidi will make the final investment decision by the end of the year. The plant could be operational in 2019.

Hydrogen from biomethane; gasoline & diesel from tree residue; cellulosic ethanol among new proposed California LCFS fuel pathways

December 18, 2015

California Air Resources Board (ARB) staff posted 32 new Low Carbon Fuel Standard (LCFS) fuel pathway applications for comments at the LCFS website. Among the multiple applications for different processing pathways of corn or sorghum ethanol are four pathways from LytEn for hydrogen produced from biomethane; four pathways for renewable gasoline and diesel produced from tree residue from Ensyn; and one application for cellulosic ethanol using corn stover feedstock from POET.

The LCFS is a regulation to reduce the carbon intensity (CI) of fuels sold in California by 10% by 2020. The LCFS applies to liquid and non-liquid fuels. If a product is above the annual carbon intensity target, the fuel incurs deficits. If a product is below that target, the fuel generates credits which may be used later for compliance, or sold to other producers who have deficits. So far, fuel producers are over-complying with the regulation. (Earlier post.)

IH2 biomass to drop-in fuels technology demonstration plant to be built in India

December 13, 2015

Shell India Markets Pvt Ltd (SIMPL) will proceed with the installation of a 5 tonne/day IH2 technology demonstration plant on the site of SIMPL’s new Technology Centre in Bangalore, India. SIMPL will build, operate and own the demonstration scale IH2 plant. IH2 technology is a continuous catalytic thermo-chemical process which converts a broad range of forestry/agricultural residues and municipal wastes directly into renewable hydrocarbon transportation fuels and/or blend stocks. (Earlier post.)

The IH2 technology was developed by US-based Gas Technology Institute in 2009 and is being further developed in collaboration with CRI Catalyst Company (CRI), Shell’s Catalyst business. CRI will supply the proprietary catalysts for the unit. The Basic Engineering Package for the plant will be provided by Zeton, Inc. of Ontario, Canada.

Boeing, Canadian aviation industry launch sustainable aviation biofuel project using forestry waste

December 03, 2015

Boeing, the University of British Columbia (UBC) and SkyNRG, with support from Canada’s aviation industry and other stakeholders, are collaborating to turn leftover branches, sawdust and other forest-industry waste into sustainable aviation biofuel.

Canada, which has extensive sustainably certified forests, has long used mill and forest residues to make wood pellets that are used to generate electricity. A consortium that includes Boeing, Air Canada, WestJet, Bombardier, research institutions and industry partners will assess whether forest waste could also be harnessed to produce sustainable aviation biofuel using thermochemical processing.
