摘要
合成了基于NiMo(W)硫化物和ZSM-23-Al2O3复合载体的双功能催化剂，研究了它们在不同含氮柴油馏分(<1;10和20ppm)进行了研究。结果表明，使用合成的催化剂可获得冷过滤器堵塞点≤- 38℃的氢化物，满足GOST R 55475-2013对汽油馏分、芳香族化合物含量和衍生十六烷数的要求。比较了所研制的两种硫化物催化剂的性能以及所得到的氢化物的特性。此外，开发的样品的性能与商业进口的异脱蜡铂基催化剂的性能进行了比较。实验结果表明，该催化剂的选择性低于参考样品，但对原料中含氮化合物具有更好的抗性。
Studying the Hydroisomerization of Diesel Fractions with Different Concentrations of Nitrogen-Containing Compounds on Bifunctional Catalysts Based on ZSM-23 and Non-Noble Metals
Bifunctional catalysts based on NiMo(W) sulfides and ZSM-23-Al2O3 composite supports were synthesized, and their properties in the conversion of diesel fractions with different contents of nitrogen (<1; 10 and 20 ppm) were studied. The possibility of using the synthesized catalysts to obtain hydrogenates with a cold filter plugging point of ≤ −38°C that meets the requirements of GOST R 55475-2013 in terms of the content of the gasoline fraction, aromatic compounds, and the derived cetane number is shown. The properties of the developed catalysts based on NiMo and NiW sulfides and the characteristics of hydrogenates obtained are compared. In addition, the properties of the developed samples are compared to those of a commercial imported isodewaxing platinum based catalyst. The developed catalysts were found to be less selective than the reference sample, but have better resistance to N-containing compounds in the feedstock.
