Abstract

Bifunctional zeolite-containing catalysts based on transition metal sulfides were synthesized, their physicochemical characteristics were determined, and the catalytic properties toward n-hexadecane hydroconversion were examined. ZSM-5, Beta, and NH4NaY zeolites were tested as acidic components of the catalysts. The highest selectivity toward isomerization reaction was afforded by the NH4NaY zeolite-containing sulfide-based catalyst. With the view to controlling the selectivity toward cracking and isomerization reactions, the influence of the presence of nitrogen-containing bases in the feedstock was evaluated.

正十六烷在含沸石硫化物基催化剂上的加氢转化:原料中的氮杂质对加氢异构化选择性的影响

摘要

合成了基于过渡金属硫化物的双功能含沸石催化剂,测定了它们的理化特性,并研究了对十六烷加氢转化的催化性能。ZSM-5、Beta和NH 4 NaY沸石作为催化剂的酸性组分被测试。含NH 4 NaY 沸石的硫化物基催化剂提供了对异构化反应的最高选择性。为了控制对裂化和异构化反应的选择性,评价了原料中含氮碱的存在的影响。
