New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis

Green Car Congress

The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, very efficiently using light.

Tunable high-yield catalytic approach converts pyrolysis oil to bio-hydrocarbon chemical feedstocks including fuel additives

Green Car Congress

The zeolite catalyst then converts these hydrogenated products into light olefins and aromatic hydrocarbons in a yield as much as three times higher than that produced with the pure pyrolysis oil. The C 6 to C 8 aromatic hydrocarbons can be high-octane gasoline additives or feedstocks for the chemical and polymer industries.

Review of approaches to engineer microbes to produce advanced biofuels

Green Car Congress

The photosynthetic organisms will use sunlight to convert CO 2 to sugar, which the Shewanella will then convert to bio-hydrocarbons. The carbon dioxide is derived directly by a photosynthetic fuel-producing organism(s) or via intermediary biomass polymers that were previously derived from carbon dioxide.

Genencor and Goodyear Partnering on Process to Develop BioIsoprene from Sugars; To be Used in Manufacture of Tires

Green Car Congress

A technical challenge to the production of isoprene from renewable sources such as biomass has been the development of an efficient process for converting carbohydrates into isoprene. One technical challenge has been the development of an efficient process for converting sugars into isoprene. —Joseph McAuliffe.

Startup New Oil Resources commercializing hydrothermal process for conversion of biomass to gasoline-range hydrocarbons

Green Car Congress

320-390 °C, 200-420 bar) aqueous phase process which converts biomass containing cellulose, hemicellulose and lignin into a high-octane gasoline fraction. Catallo and Junk determined that reacting organic compounds in near-critical or supercritical aqueous phases can transform the compounds over short time periods (i.e.,

Researchers Identify Enzyme That Breaks Down Chitin; May Lead to Cheaper Biofuels

Green Car Congress

In theory it’s easy to convert the carbohydrates in cellulose, for instance, to small sugar molecules that nourish microorganisms which in turn produce methane and ethanol. The respective carbohydrate polymers of both chitin and cellulose form extremely dense, resilient bonds. But in practice, it has proven to be quite challenging.

Gevo awarded $5M to develop cellulosic jet fuel; separate contract to supply alcohol-to-jet drop-in biojet fuel to USAF

Green Car Congress

In July 2010, Gevo reported the successful production of isobutanol from fermentable sugars derived from cellulosic biomass. The company also successfully converted the cellulosic isobutanol into isobutylene and paraffinic kerosene (jet fuel).( Earlier post.). without the typical expression of co-products. Earlier post.).
