摘要
镁铝尖晶石是一种重要的脱硫（Ｄｅ－ＳＯｘ）助剂，本文利用原位热重技术研究酸法制备的三种尖晶石在不同反应条件下氧化吸硫情况，重点考察金属元素铈和铁对尖晶石的调变作用．
De-SOx catalyst additive technology is the most economical and effective approach for deducing SOx emission from Fluid Catalytic Cracking Units(FCCU). On different kinds of conditions, Oxidization absorb sulphur of De-SOx catalyst additives, prepared by acidic method ,was studied by in situ-TG in this paper. And the promoting actions of individual component such as cerium and iron on the spinels structure were especially investigated.
