Abstract

The authors study the effect of the content of zeolite ZSM-22 (15–70 wt %) in a support on the physicochemical properties of Pt/ZSM-22–Al₂O₃ catalysts. The dependence of the yield and composition of sunflower oil hydrodeoxygenation products on these catalysts on the temperature (310–340°C), pressure (3‒5 MPa), and weight hourly space velocity (WHSV) (0.8–3 h⁻¹) is determined. The possibility is shown of the full hydrodeoxygenation of sunflower oil with the formation of C₅₊ hydrocarbons containing up to 72% of iso-paraffins with yields of 75–79 wt %.

不同含量沸石 ZSM-22 双功能催化剂在葵花籽油氢脱氧反应中的理化和催化特性

摘要作者研究了载体中沸石 ZSM-22 的含量（15-70 wt %）对 Pt/ZSM-22-Al2O3 催化剂理化性质的影响。测定了这些催化剂上葵花籽油加氢脱氧产物的产量和组成与温度（310-340°C）、压力（3-5 兆帕）和重量时空速度（WHSV）（0.8-3 h-1）的关系。结果表明，葵花籽油可以完全加氢脱氧，形成 C5+ 碳氢化合物，其中异链烷烃含量高达 72%，产率为 75-79 wt%。
