Scientists at the National Energy Technology Laboratory (NETL; Morgantown, W. Va.; www.netl.doe.gov) have demonstrated a process for enhancing the efficiency of the water-gas shift (WGS) reaction. The process revolves around a magnesium hydroxide sorbent material that can remove CO2 from coal gasification products at elevated temperatures. The industrially significant WGS reaction, often used to increase...

A typical fluid catalytic cracking unit (FCC) generates about 200 tons/d of dry gas — a mixture of off-gases that is burned as refinery fuel. However, about 40 tons of that gas is ethylene, which would have much greater value as gasoline or diesel fuel. A process that converts better than 40% of the ethylene to motor fuels in a single pass is being developed by UOP LLC, a Honeywell...
