Investigations of enzymatic transesterification of castor oil for biodiesel production

he search for renewable biofuels to replace fossil fuels

makes biodiesel production a fairly strait forward choice,

both from a production and application point of view, in as

much as the processing technology is readily available and

only minor changes to the existing fuel distribution network

and diesel engines are needed. Unfortunately, at present most

biodiesel is produced by transesterification of edible vegetable

oils produced on lands useful for producing crops for feed and

fodder. This makes biodiesel production less attractive from

a resource and sustainability point of view. There are crops

available that do grow in arid soils not normally attractive for

production of food or fodder. One such crop is castor beans.

The oil produced from castor beans, castor oil, is not suitable

for human consumption but can be used as a starting point for

polymer production, as lubricant, and, if mixed with other fatty

methyl or ethyl esters, after transesterification for biodiesel.The

work presented gives an overview of the results obtained from

transesterification of castor oils using the non-immobilized

enzymes Eversa Transform and Resinase HT, the immobilized

enzyme Novozyme 435, combining kinetic studies and enzyme

reuse with process simulation.
