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

摘要

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 (1,2). At least one of such reactors (1) processes heavy gas oil or residue (A) under conventional conditions whilst at least one of such reactors (2) processes the charge of vegetable origin (B) made from seeds of oleaginous plants under conditions suitable for production of diesel oil. Said process employs the same catalyst utilised 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 oxidised and consequently purer than products obtained by means of existing technology.
