能抑制镍钒中毒的渣油裂化催化剂目前，炼油工业上利用低成本重质渣油馏分作进料油日益增多。但主要的问题是，渣油中存在的镍和饥这类有机金属化合物会引起结焦从而降低成品收率。为了使炼油厂能有效地利用渣油原料，最近，美国Ｅｎｇｅｌｈａｒｄ公司正在工业化生产一种... Residue cracking catalysts that inhibit nickel-vanadium poisoning At present, the use of low-cost heavy residual oil fractions as feedstocks in the refining industry is increasing. But the main problem is that the presence of nickel and other organometallic compounds in the residue can cause coking and thus reduce the yield of finished products. In order to make the refinery can effectively use the residue of raw materials, the United States recently Engelhard company is industrial production of a ...
