要旨

[Zn,Mo]/HZ-5 catalysts were prepared using an impregnation method and the influence of Mo content on the catalytic performance was investigated. All prepared catalysts were well characterized by XRD, FTIR, N2 adsorption/desorption, TEM, ICP, XPS, NH3-TPD, Py-FTIR and GC-MS. It was found that coaromatization had higher aromatics yield and more stability. The modification with Mo species adjusted the acidity of Zn/HZ-5 and increased the amount of Zn(OH)+ species. As a result, [Zn,Mo]/HZ-5 improved the dehydroaromatization ability and provided higher aromatics yield. The behaviors of carbon deposit and deactivation were also studied. The BTEX yield reached the maximum of 64.0% under the optimized conditions of 470 °C and WHSV = 1.0 h−1.

Reaction Chemistry & Engineering is an interdisciplinary journal reporting cutting-edge research focused on enhancing the understanding and efficiency of reactions. Reaction engineering leverages the interface where fundamental molecular chemistry meets chemical engineering and technology. Challenges in chemistry can be overcome by the application of new technologies, while engineers may find improved solutions for process development from the latest developments in reaction chemistry. Reaction Chemistry & Engineering is a unique forum for researchers whose interests span the broad areas of chemical engineering and chemical sciences to come together in solving problems of importance to wider society. All papers should be written to be approachable by readers across the engineering and chemical sciences. Papers that consider multiple scales, from the laboratory up to and including plant scale, are particularly encouraged.
