The present invention comprises a thermocatalytic cracking process for the production of diesel oil from a charge of vegetable origin made from seeds of oleaginous plants in refineries possessing at least two FCC reactors. At least one of such reactors processes heavy gas oil or residue under conventional conditions while at least one of such reactors processes the charge of vegetable origin made from seeds of oleaginous plants under conditions suitable, for production of diesel oil. Said process employs the same catalyst utilized in the fluid catalytic cracking process which, simultaneously, processes a conventional charge. The diesel, or biodiesel, oil produced by means of said process is of superior quality having a cetane number exceeding 40 given that the cracking reactions occur at low temperatures and the products obtained are less oxidized and consequently purer than products obtained by means of existing technology.

Catalytic cracking process for production of diesel from seeds of oleaginous plants

An integrated process is described for producing biodiesel from oleaginous seeds, preferably castor bean seeds. The inventive process includes a transesterification reaction where the seeds themselves react with anhydrous ethyl alcohol in the presence of an alkaline catalyst. The resulting ethyl esters are then separated by decantation and neutralized and used as fuel for diesel engines, co-solvents for diesel and gasoline mixtures with anhydrous or hydrated ethyl alcohol. The solid fractions may be used as fertilizers, for feeding cattle and as a raw material for producing ethyl alcohol.
