Abstract

A methanol conversion catalyst based on natural aluminosilicate nanotubes and H–ZSM-5 zeolite was synthesized. Its textural, structural, and acid properties were studied by low-temperature nitrogen adsorption–desorption, transmission electron microscopy, X-ray diffraction analysis, and temperature-programmed ammonia desorption. The influence exerted on the methanol conversion and product distribution by the reaction temperature (380–460°С), pressure (0.1–0.5 MPa), and feed space velocity (0.5–1 h–1) was studied. The catalyst based on halloysite aluminosilicate nanotubes showed high selectivity in formation of both lower olefins and aromatic hydrocarbons.

摘要

合成了一种基于天然铝硅酸盐纳米管和 H-ZSM-5 沸石的甲醇转化催化剂。通过低温氮吸附-解吸、透射电子显微镜、X 射线衍射分析和程序升温氨解吸研究了其结构、结构和酸性质。研究了反应温度 (380–460°С)、压力 (0.1–0.5 MPa) 和进料空速 (0.5–1 h –1 )对甲醇转化率和产物分布的影响。基于埃洛石铝硅酸盐纳米管的催化剂在形成低级烯烃和芳烃方面表现出高选择性。
