Meoh reaction
Methanol is behalve door gisting ook eenvoudig te synthetiseren uit gangbare chemische grondstoffen, steenkool of uit biomassa. Methanol wordt tevens gemaakt uit aardgas (hoofdzakelijk methaan) en stoom en over een nikkel-katalysator geleid, waarbij stoom in overmaat aanwezig is in een verhouding van 3:1.
