Three-part catalyst study advances conversion of CO2 to ethanol

Green Car Congress

An international collaboration of scientists has taken a significant step toward the realization of a nearly “green” zero-net-carbon technology that can efficiently convert CO 2 and hydrogen into ethanol. None of the three components examined in the study is able to individually catalyze the CO 2 -to-ethanol conversion, nor can they in pairs.

Oxford team directly converts CO2 to jet fuel using iron-based catalysts

Green Car Congress

The catalyst shows a carbon dioxide conversion through hydrogenation to hydrocarbons in the aviation jet fuel range of 38.2%, with a yield of 17.2%, and a selectivity of 47.8%, and with an attendant low carbon monoxide (5.6%) and methane selectivity (10.4%). In brief, the Fe–Mn–K catalyst shows a CO 2 conversion of 38.2%

UNSW Syndey team develops hydrogen-diesel dual fuel system; 90% H2, more than 85% reduction in CO2

Green Car Congress

Engineers from UNSW Sydney (Australia) have successfully converted a diesel engine to run as a dual-fuel hydrogen-diesel engine, reducing CO 2 emissions by more than 85% compared to conventional diesel. In a paper published in the International Journal of Hydrogen Energy, Prof. below the amount produced by the diesel powered engine.

Stanford engineers develop catalyst strategy to improve turnover frequencies for CO2 conversion to hydrocarbons by orders of magnitude

Green Car Congress

Researchers at Stanford University have shown that porous polymer encapsulation of metal-supported catalysts can drive the selectivity of CO 2 conversion to hydrocarbons. CO 2 (black and red) and hydrogen molecules (blue) react with the help of a ruthenium-based catalyst. Chengshuang Zhou, Arun S. Asundi, Emmett D. Hoffman, Sindhu S.

New process uses localized surface plasmons for room-temperature conversion of CO2 to CO

Green Car Congress

The conversion normally requires significant amounts of energy in the form of high heat—a temperature of at least 700 ?C, Carbon monoxide readily combines with hydrogen to produce essential hydrocarbon compounds, such as methane and ethanol, that are often used in industry, said NIST researcher Renu Sharma.
