description La presente se refiere a un procedimiento de craqueo termocatalítico, para la produccion de aceite diesel a partir de aceites vegetales, en refinerías que tienen como mínimo dos reactores de FCC. Por lo menos uno de los reactores procesa gas oil pesado o residuos en condiciones convencionales, mientras que por lo menos uno de los reactores procesa aceites vegetales en condiciones adecuadas para la produccion de aceite diesel. El proceso utiliza el mismo catalizador utilizado en el proceso de craqueo catalítico fluido, el cual, simultáneamente, procesa cargas convencionales. El proceso transforma materias primas con alto valor calorico en hidrocarburos combustibles y tiene excelente eficacia para la obtencion de productos con alta pureza, sin presentar la formacion de glicerina, un subproducto del proceso de transesterificacion. El aceite diesel producido mediante dicho procedimiento tiene calidad superior, presenta numero de cetano mayor de 40, ya que las reacciones de craqueo se producen a temperaturas bajas, y los productos obtenidos son menos oxidados, y por lo tanto más puros, que los productos obtenidos mediante la tecnología existente. The present invention relates to a thermo catalytic process to produce diesel oil from vegetable oils, in refineries which have two or more Catalytic Cracking (FCC) reactors. At least one reactor processes heavy petroleum or residue in conventional operation conditions while at least one reactor processes vegetable oils in proper operation conditions to produce diesel oil. This process employs the same catalyst employed in the FCC process, which processes conventional feedstocks simultaneously. This process transforms high heat content raw materials into fuel hydrocarbons. It may improve efficiency for the obtainment of highly pure products and may not yield glycerin, one by-product of the transesterification process. The diesel oil produced by said process may have superior qualities and/or a cetane number higher than 40. Once cracking conditions occur at lower temperatures, it may form a less oxidized product, which is consequently purer than those obtained by existent technology.
