Abstract

PROCESSO DE FCC PARA A MAXIMIZAçãO DE DESTILADOS MéDIOS E descrito um processo de FCC para a maximização de destilados médios a partir de cargas de diferentes origens, pelo contato da dita carga que circula no dito riser com um catalisador particulado fino proveniente de um regenerador (6), sob condições de FCC de máximo LCO, a temperaturas entre 480<198>C e 520<198>C, em ausência de hidrogênio adicionado, e com injeção de fluido refrigerante ou quench em um riser ascendente R, e onde dito processo compreende a injeção de uma proporção entre 200 e 50 kg de fluido refrigerante por m¬ 3¬ de carga, de preferência entre 100 e 50 kg/m¬ 3¬ de carga, em uma região (3) do dito riser ascendente R situada em uma posição entre 25% e 50% da altura do dito riser R acima dos bocais de carga (2), a injeção nessa posição tendo como conseqüência o aumento da circulação de catalisador e aumento da temperatura no trecho inicial do riser, pelo que é atingida produção de destilados médios de teor de aromáticos mais baixo e onde a conversão de fundos é menor do que quando a injeção do dito fluido refrigerante é efetuada na base do dito riser R como nos processos do estado da técnica.FCC PROCESS FOR MEDIUM DISTILLATED MAXIMIZATION An FCC process for maximizing middle distillates from loads of different origins is described by contacting said charge circulating in said riser with a fine particulate catalyst from a regenerator (6). ), under conditions of maximum LCO FCC, at temperatures between 480 <198> C and 520 <198> C, in the absence of added hydrogen, and with injection of refrigerant or quench in an upward riser R, and wherein said process comprises injecting a proportion of between 200 and 50 kg of refrigerant per m¬ 3¬ load, preferably between 100 and 50 kg / m¬ 3¬ load, in a region (3) of said rising riser R situated in a position between 25% and 50% of the height of said riser R above the loading nozzles (2), injection in this position resulting in increased catalyst circulation and increased temperature in the initial riser stretch, whereby production is achieved. in medium distillates of lower aromatic content and where the conversion of bottoms is lower than when injection of said refrigerant is performed on the basis of said riser R as in prior art processes.
