Abstract
PROCESSO E PARATO PARA A MAXIMIZAçãO DE DESILADOS MéDIOS DE FCC São descritos um processo a aparato para a maximização de destilados médios de FCC, dito processo compreendendo o craqueamento de uma carga 10 de hidrocarbonetos pesados em presença de catalisador e em ausência de hidrogênio adicionado, em um aparato compreendendo um primeiro riser 21 operando em condições de baixa severidade, T = 460-520C, produzindo produtos 32 mais leves separados em um separador 30, e um segundo riser 23 de lata severidade, T = 550-620EC, dito riser atuando também como resfriador de catalisador e produzindo produtos 42 separados em separador 40, os catalizadores separados de 30 e 40 sendo dirigidos a um retificador 43 por um duto 44, e sendo injetados no dito riser 23 as correntes 67e 68 de HCO ou suas frações mais leves, além da corrente de nafta leve 64.Os produtos 32 e 42 são fracionados respectivamente nas torres 60 e70. O catalisador recoberto de coque é regenerado em 50. O destilado médio obtido é de baixa aromaticidade, a nafta craqueada é de alta octanagem,e propeno e eteno são obtidos em proporções superiores áquelas de processos convencionais de FCC com baixa conversão.FCC MEDIUM DISILLED MAXIMIZATION PROCESS AND PARATE An apparatus process for maximizing FCC medium distillates is described, said process comprising cracking a heavy hydrocarbon charge 10 in the presence of catalyst and in the absence of added hydrogen, in an apparatus comprising a first riser 21 operating under low severity conditions, T = 460-520C, producing lighter products separated into a separator 30, and a second high severity riser 23, T = 550-620EC, said riser acting also as catalyst cooler and producing separate products 42 in separator 40, separate catalysts 30 and 40 being directed to a rectifier 43 by a duct 44, and being injected into said riser 23 HCO streams 67e 68 or their lightest fractions, in addition to the light naphtha stream 64. Products 32 and 42 are split into towers 60 and 70 respectively. The coke-coated catalyst is regenerated at 50 ° C. The average distillate obtained is of low aromaticity, cracked naphtha is of high octane, and propene and ethylene are obtained in higher proportions than those of conventional low conversion FCC processes.
