摘要：

某公司开发了一种新型重油裂化催化剂GDmax。该催化剂以结构优化分子筛为核心，采用新型改性硅铝基技术制备而成，具有更多的活性中心、更大的比表面积和更好的孔分布，现已在国外某催化裂化装置投入工业应用。工业应用结果表明：在催化裂化原料油性质和操作条件相当的情况下，与应用前相比，应用GDmax催化剂后，干气（含部分C₃）收率下降了0.35个百分点；液化石油气收率升高了1.77个百分点（其中丙烯、丁烯的收率分别升高了0.37、0.36个百分点）；汽油收率升高了1.00个百分点；油浆和焦炭的收率分别降低了0.53、0.24个百分点。说明GDmax催化剂具有较好的低碳烯烃选择性、较强重油转化能力和良好的焦炭选择性，能显著提高高附加值产品收率、降低焦炭和干气收率。

Abstract:

A new heavy oil cracking catalyst, GDmax, was developed by a company. It has more active centers, a larger surface area, and better pore distribution. It has been used in a foreign catalytic cracking unit. The results show that, compared with before, after using GDmax catalyst, the dry gas (including part of C₃) yield decreased by 0.35%, the liquefied petroleum gas (LPG) yield increased by 1.77%, where propylene and butene yields increased by 0.37% and 0.36% respectively, the gasoline yield increased by 1.00%, and the yields of slurry and coke decreased by 0.53% and 0.24% respectively. The GDmax catalyst has good low-carbon olefin selectivity, strong heavy oil conversion ability, and good coke selectivity, which can significantly increase the yield of high-value products and reduce the yield of coke and dry gas.
