However, physical refining is not recommended in the case of castor oil, due to its sensitivity to heat as it normally starts disintegrating above 150°C, which can result in the hydrolysis of the hydroxyl groups.
Can a castor oil biorefinery produce biodiesel and biochemicals simultaneously?
Goal and outline The goal of this paper is conceptual design, simulation and economic analysis of a castor oil biorefinery for producing simultaneously biodiesel and bio-chemicals. Four distinct processes are studied, from which two regard castor oil transesterification, followed by fatty ester pyrolysis and undecylenic acid amination.
How Castor oil biorefinery process fatty methyl ricinoleate ester (famre)?
The first processing step in a castor oil biorefinery is the synthesis of fatty methyl ricinoleate ester (FAMRE) by transesterification. FAMRE can be valorised firstly as biodiesel. Further a certain amount of FAMRE is submitted to conversion in bio-chemicals.
What is Castor processing flow diagram?
Castor processing flow diagram. The first step in the castor oil refining process, called degumming, is used to reduce the phosphatides and the metal content of the crude oil.
