摘要

Process for maximizing middle distillates of FCC with production inputs petroquu00ecmicos and maximum return.The present invention enables the operation of a FCC unit so as to produce a LCO of excellent qualities for incorporation into the pool of diesel, concomitantly with the production of propene and ethene to petrochemical, with incomes greater than those of a unit of FCC Convencion Al and low income of oil decanted in relation to a conventional operation in low severity.In addition, you can adjust the yield and the quality of gasoline produced, according to the demand.The present invention provides a process for the maximization of middle distillates, production of raw materials and petrochemical naphtha hydrodessulfurization high octane in fluid catalytic cracking units, from mixed loads of hydrocarbons, using a system of two reactors of you. Po riser, that operate simultaneously under conditions of different severity.The first riser, low severity, maximizes the production of LCO, and the second, high severity, is dedicated to the production of petrochemicals. The unit operates at maximum profitability, since it maximizes noble products and does not need to recycle any current to achieve its goals.The present invention also teaches a way of increasing the efficiency of grinding in the operation of low severity, because even though the first riser operating in low temperature reaction, the temperature increase of grinding is obtained through mixing with The effluent from the second riser catalyst, mixture that held before the rectifier power.
