USC team develops highly efficient catalyst system for converting CO2 to methanol; 79% yield from CO2 captured from air

Green Car Congress

They recycled the catalyst over five runs without significant loss of activity (turnover number > 2000). Though mixed with water, the resulting methanol can be easily distilled, Prakash said. CO 2 capture from air and conversion to CH 3 OH. They then heated the solution, converting 79% of the CO 2 into methanol. —G.K.

Researchers Propose Solar-Driven Biomass Gasification Pathway for Synthetic Fuel Production

Green Car Congress

Hydrogen for reverse water gas shift reaction to avoid producing CO 2 during the process is produced by electrolyzing water, driven by solar power. Hot syngas from the gasifier is cooled and cleaned, then compressed to the reformer (methane reforming) and the reverse water gas shift (Re-WGS) reactor. Hertwich and Zhang (2009).

Final session on international mercury convention this week expected to culminate in agreement; UNEP Global Mercury Assessment 2013 finds industrial source Hg emissions may be rising

Green Car Congress

The session is expected to culminate in the adoption of a new convention by the 147 states attending the session to reduce mercury emissions and releases to the air, water and land. The 2013 assessment is the most comprehensive to date, and includes information on the release and impacts of mercury in aquatic environments for the first time.
