摘要 采用溶胶-凝胶法制备具有介孔结构的降硫基质材料,选择具有降硫选择性的活性元素对合成的基质材料进行改性处理,考察不同的改性方法对制得的催化裂化原位降硫助剂性能的影响,并对基质材料和降硫助剂的结构进行表征。采用美国进口的ACE-R小型催化裂化评价装置将降硫助剂与催化裂化催化剂匹配进行性能评价,在不改变原催化裂化产品分布和产品性质的同时,降低原料的总硫含量,总硫降低可达40%以上。 Adopt sol-gel method to preparation reduce-sulphur agents with Mesoporous structure, select the component to mix the materials and get the structure characterization of reduce-sulphur agents using difference method treated. Adopt ACE small-sized appraisement of catalytic cracking to appraise the reduce-sulphur auxiliaries, while not change the product distribution and product nature of catalytic cracking, the total sulfur content and total sulphur that reduces can reach 40%.
