Catalytic cracking process for production of diesel from vegetable oils

摘要

"The process of catalytic cracking for the production of diesel from vegetable oils. The present invention includes a process for cracking termocatalu00edtico, for the production of diesel fuel from vegetable oils, in refineries which have a minimum of two reactors of FCC.At least one of the reactors processes heavy gas oil or residue in conventional conditions while at least one of the reactors processing vegetable oils under conditions suitable for the production of diesel oil. The process uses the same catalyst used in the process of fluid catalytic cracking, which, at the same time, processes the conventional load.The process transforms raw materials with a high calorific value of fuel hydrocarbons and exhibits excellent efficiency for obtaining products with high purity and does not present the formation of glycerol, a by-product of the process of transesterificau00e7u00e2o.The diesel oil produced through the said process has superior quality, presents a cetane number higher than 40, because the cracking reactions occur at low temperatures and the products obtained are less oxidised, and hence more pure than the products obtained through the technology.
