Question

谁能帮我翻译一下下面这段话，不要用翻译软件来翻，最好是意译，不要直译

本文以有害金属对裂化催化剂的污染为基础，分析了镍、钒、铁、钠、钙对分子筛孔结构、酸性的作用以及对催化剂活性、选择性的影响，探讨了金属钝化剂与有害金属的作用、钝化机理和在优化催化剂使用环境、改善产品分布等方面的积极作用，提出了无毒、高效、多功能的金属钝化剂未来发展方向。
不要用翻译软件来翻译，要那样我就不求助了，希望能意译

Answer 1

This article take the harmful metal to the cracking catalyst pollution as a foundation, has analyzed the nickel, the vanadium, the iron, the sodium, the calcium to the molecular mesh structure, the acidic function as well as to the catalyst activeness, the selective influence, has discussed the metal passivator and the harmful metal function, deactivates aspect and so on mechanism and in optimized catalyst use environment, improvement product distribution positive roles, proposed non-toxic, highly effective, the multi-purpose metal passivators in the future the development direction.

Answer 3

In this paper, the harmful metals pollution of cracking catalyst, based on an analysis of nickel, vanadium, iron, sodium, calcium on the zeolite pore structure, the role of acid and catalyst activity, selectivity of the effects of harmful metals and metal passivator the role of the passivation mechanism and catalyst in optimizing the use of the environment, improve the product distribution of an active role in a non-toxic, highly efficient, multi-functional metal passivator the direction of future development.
