Abstract: Sweet dream Biodiesel is a clean-burning fuel made from vegetable oils by transesterification, a process producing methyl esters (the fuel) and glycerin (used in soap and other products). Sounds good but there is a snag: good catalysts for esterification are costly, far from ‘green’ and involve high energy consumption. A new solid catalyst made from inexpensive sugars may be the answer. It consists of sulphonated amorphous carbon, is recyclable and is more efficient than other solid catalysts so far tested.
