摘要： A hydrofining process in which a sulfur- and hydrocarbon-containing processing stream is supplied to a multi-stage hydrotreating reactor incorporating separate stages of cobalt molybdenum catalysts. Hydrogen may be supplied concurrently or counter-currently with the hydrocarbon-containing processing stream. The processing stream is passed into contact with an initial catalyst stage comprising a cobalt molybdenum desulfurization catalyst present in a minor amount of the total composite amount of catalysts within the reactor. Thereafter the processing stream is passed through a subsequent catalyst stage comprising a major amount of cobalt molybdenum hydrocracking catalyst. The effluent stream having a reduced sulfur content is then withdrawn from the hydrotreating reactor. The initial and subsequent catalyst stages are separated by an intervening sector within the reactor containing an inert particulate refractory material, specifically silica particles generally spheroidal in shape.

摘要翻译： 一种加氢精制方法，其中将含硫和烃的加工流供应到加入分开的钴钼催化剂阶段的多级加氢处理反应器中。 氢气可与含烃处理物流同时或逆流供应。 使处理物流与初始催化剂阶段接触，所述初始催化剂阶段包含存在于反应器内少量的催化剂总复合量中的钴钼脱硫催化剂。 此后，使处理物流通过包含主要量的钴钼加氢裂化催化剂的随后的催化剂阶段。 然后将具有降低的硫含量的流出物流从加氢处理反应器中排出。 初始和随后的催化剂阶段由反应器内的介入扇区分离，该介入扇区包含惰性颗粒状耐火材料，特别是二氧化硅颗粒，通常为球形。
