With respect to transportation fuels, renewable methanol can substitute current low, medium and high conventional methanol blends. Through the electrofuel production process, it can be turned into a drop-in fuel for gasoline, diesel and marine engines. The Renewable Methanol Production Processes from Different Feedstocks.
Methanol synthesis is a mature technology. The feedstock is typically a mixture of CO2, CO, and hydrogen, and catalysts are mainly based on copper or copper/zinc oxide. Typical methanol plant carbon efficiencies can range from 89-95%. Among several opportunities like carbon efficiency improvement, adjustment of methanol loop process conditions
