Abstract

The study investigated, for the first time with respect to Fischer–Tropsch synthesis of fuels, cobalt-containing catalytic systems based on SAPO-11 molecular sieves with differing secondary porous structure characteristics. Various methods, such as XRD, low-temperature nitrogen adsorption/desorption, SEM, TEM, H₂-TPD, and NH₃-TPD, were used to characterize the prepared catalysts, which were subsequently examined in hydrocarbon synthesis at 2.0 MPa, 240°C, and gas WHSV = 1000 h^–1. The study demonstrated good prospects for micro/mesoporous-structured SAPO-11 as an acid catalyst component for fuel production.

燃料费-托合成中基于SAPO-11分子筛的双功能含钴催化体系

摘要

该研究首次针对费托合成燃料研究了基于具有不同二级多孔结构特征的SAPO-11分子筛的含钴催化体系。使用各种方法（如XRD，低温氮吸附/解吸，SEM，TEM，H ₂ -TPD和NH ₃ -TPD）表征制得的催化剂，随后在2.0 MPa，240的烃合成中对其进行检查°C，且气体WHSV = 1000 h ^–1。该研究证明了微/中结构SAPO-11作为用于燃料生产的酸催化剂组分的良好前景。
