Researchers show mixotrophic fermentation process improves carbon conversion, boosting yields and reducing CO2

Green Car Congress

Consequently, first and second generation bioproduct manufacturing processes are economically challenged, particularly in light of recent low oil prices. One way to mitigate high feedstock cost is to maximize conversion into the bioproduct of interest. Jones, Alan G. Fast, Ellinor D. Carlson, Carrissa A. Papoutsakis & Bryan P.

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.

Purdue analysis finds H2Bioil biofuel could be cost-competitive when crude is between $99–$116/barrel

Green Car Congress

Their analysis is published in the journal Biomass Conversion and Biorefinery. The break-even crude oil price for a delivered biomass cost of $94/metric ton when hydrogen is derived from coal, natural gas or nuclear energy ranges from $103 to $116/bbl for no carbon tax and even lower ($99–$111/bbl) for the carbon tax scenarios.

Global Bioenergies reports first production of green isobutene at demo plant

Green Car Congress

With a nameplate capacity of 100 tons/year, the demo plant will allow the conversion of various resources (industrial-grade sugar from beets and cane, glucose syrup from cereals, second-generation sugars extracted from wheat straw, bagasse, wood chips…), into high-purity isobutene. Earlier post.).

Startup Siluria Technologies developing novel bio-templated catalysts for economic direct conversion of methane to ethylene; potential for transportation fuels

Green Car Congress

It’s a robust technology, but you have to pay the oil price, and if you have to burn an awful lot of heat in order to enable that endothermic chemistry, if you were to care about the energy footprint of this, it’s the three pounds of CO 2 produced to make one pound of polyethylene. in a 1997 paper in Science.
