Abstract
본 발명은 40내지 80중량% 범위내의 파라핀류, 0.5내지 7중량%범위내의 나프텐류, 6내지 45중량% 범위내의 방향족 탄화수소류로 이루어지며 최대증류 온도가 70내지 90℃인 공급 원료를 소소화시킨 후에, 상기 수소화 단계로부터 얻은 유출물을 이성질체화시켜서 가솔린 분류물중의 벤젠 함유량을 감소시키는 방법으로서, C5-C6분류물을 상기 공급원료 및/또는 상기 유출물과 혼합하는 것을 특징으로 하는 방법에 관한 것이다.The present invention consists of paraffins in the range of 40 to 80% by weight, naphthenes in the range of 0.5 to 7% by weight, aromatic hydrocarbons in the range of 6 to 45% by weight and digests the feedstock having a maximum distillation temperature of 70 to 90 ° C. After which the effluent obtained from the hydrogenation step isomerized to reduce the benzene content in the gasoline fraction, wherein the C 5 -C 6 fraction is mixed with the feedstock and / or the effluent. It is about how to.
