洛阳石油化工工程公司炼油实验厂 (下称炼油实验厂 )催化裂化装置从早期的掺炼渣油及后来的渣油改质实验 (ＲＯＰ) ,到 2 0世纪 90年代进行的原料残炭高达 8%的常压渣油催化裂化工程开发的整个过程 ,反应油气管道均不同程度地出现过结焦。油气管道结焦后 ,轻者压力降升高 ,使反 Luoyang Petrochemical Engineering Refining Experimental Plant (hereinafter referred to as the Refinery Experimental Plant) catalytic cracking unit from the early blending residue oil and subsequent residue modification experiments (ROP), to the 20th century, 90 raw carbon residue up to 8 % Of atmospheric residue catalytic cracking project development throughout the process, the reaction of oil and gas pipelines have varying degrees of coking. After the oil and gas pipe coking, light pressure drop higher, so anti
