PNAS study finds Vertimass CADO efficient way to convert ethanol to biohydrocarbons; 40 to 96% reduction in GHGs, based on feedstock

Green Car Congress

Unlike prior processes for converting alcohols into hydrocarbons with multiple steps for dehydration, oligomerization, and hydrogenation, the Vertimass consolidated alcohol dehydration and oligomerization (CADO) conversion is accomplished in a single reactor system using a metal exchanged zeolite catalyst. GJ in the near future.

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

Kreutz used two examples of CCTF systems in his analysis: biodiesel from microalgae and Sandia National Laboratory’s S2P process (an effort to utilize concentrated solar energy to convert waste CO 2 into synthetic fuels, earlier post ). emissions. In CCTF, the source of CO 2 determines the net carbon intensity of the fuel, Kreutz says.

Study details viable pathway to develop sustainable aviation biofuels industry in Pacific Northwest; hydroprocessing of natural oils seen as the most immediate opportunity

Green Car Congress

Established hydroprocessing technologies to produce aviation fuels from natural oils. supply chains for sustainable aviation fuels utilizing oils from oilseed crops such as camelina, as well as algae and biomass. Natural bio-oils have carbon chain lengths that are in the diesel range, 16-18 carbon atoms in the hydrocarbon.

The Real Reason for USA based Economic Recessions.

DIY Electric Car

The True Cause of Recessions: OIL. I was asked to speak about the economic impact of our oil dependency and so I began researching this topic to see if I could draw some insightful conclusions. All of the recessions listed above were caused by oil except the early 2000 recession that was caused by September 11th, 2001.

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

Green Car Congress

An important precursor for some types of synthetic rubber is isoprene, a highly volatile hydrocarbon which is typically obtained as a by-product from refining crude oil. One technical challenge has been the development of an efficient process for converting sugars into isoprene. —Joseph McAuliffe. —Joseph McAuliffe.

Study finds that dry-feed gasification for coal-to-liquids is more efficient, lower-emitting and cheaper than slurry-feed; CCS cost-effective for reduction of CO2

Green Car Congress

Conventional CTL plant gasifies coal to produce a syngas which is then converted in a Fischer-Tropsch reactor to products. Even with CCS, the liquid product costs are comparable to recent crude oil prices. For a liquids-only configuration, CCS is a cheaper option when the CO 2 price exceeds $12/tonne.
