Pt/Zr(x)-HMS/HZSM-5 catalysts with different ratios of Silicium/Zirconium (denoted as x) were studied for normal heptane reforming at 350-450 °C temperature range. For this purpose, the properties of the catalysts such as X-ray diffraction, X-ray fluorescence, Fourier-transform infrared spectroscopy, Ultraviolet–visible diffuse reflectance spectroscopy, NH3-temperature pro...

Summary Molybdenum supported on zeolite HZSM-5 is the most studied catalyst for methane dehydroaromatization. However, nature of its catalytic sites and their deactivation mechanisms remain unclear controversial. Here, we report further insights into this system: first, crystal size determines form location active MoCx species, thus performance; second, are preferentially deactivated over acid ...

Due to crude oil is limited, new resources for fuel and petrochemicals are important to be developed. Biogas or NG (Natural Gas) can be easily converted into methanol which can be reacted over zeolite to produce olefins and gasoline. HZSM-5 zeolite catalyst has been used in this study and its modification by (0.5wt%, 1wt%, 2wt% and 4wt %) Ni to convert methanol to hydrocarbons (MTH). Catalysts ...

The catalytic pyrolysis of Chlorella vulgaris, high-density polyethylene (Pure HDPE) and, their binary mixtures were conducted to analyse the kinetic and thermodynamic performances from 10 100 K/min. parameters computed by substituting experimental ANN predicted data into these iso-conversional equations plotting linear plots. Among all models, Flynn-Wall-Ozawa (FWO) model gave best prediction ...
