Rice team demonstrates more efficient photocatalyst for converting ammonia to hydrogen

Green Car Congress

Rice University nanoscientists have demonstrated a new catalyst that can convert ammonia into hydrogen fuel at ambient pressure using only light energy, mainly due to a plasmonic effect that makes the catalyst more efficient. —Naomi Halas. Linan Zhou, Dayne F. Carter, Peter Nordlander, Naomi J.

New fast hydrothermal process converts 65% of wet algae feedstock sample to biocrude in one minute

Green Car Congress

Phillip Savage at the University of Michigan has found that with appropriate parameters, hydrothermal liquefaction (HTL) can convert 65% of wet algae (a Nannochloropsis species) into biocrude in one minute. They saw their best results, with about half of the algae converted to biocrude, after treating it for 10 to 40 minutes at 570 degrees.

Navy researchers produce high energy density jet fuels from sustainable cellulosic feedstocks

Green Car Congress

For example, our group demonstrated the conversion of the acyclic terpenoid linalool to dimethyltetrahydrodicyclopentadiene (RJ-4) in 2011. More recently, researchers have shown that RJ-4 can be efficiently converted to 1,3-dimethyladamantane, a thermally stable jet fuel of interest for high speed applications. MJ/kg and 39.04

Bacterial enzyme converts carbon monoxide to hydrocarbons

Green Car Congress

Researchers at Utah State University report on an engineered bacterial enzyme—a molybdenum (Mo) nitrogenase—capable of converting carbon monoxide into usable hydrocarbons in a reaction similar to Fischer-Tropsch synthesis. Seefeldt (2011) Molybdenum nitrogenase catalyzes the reduction and coupling of CO to form hydrocarbons J.
