Micro-Mesoporous Catalyst Based on Natural Aluminosilicate Nanotubes and ZSM-5 Zeolite for Methanol Conversion to Hydrocarbons

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-p...

Summary: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.
