An overview of reforming technologies and the effect of parameters on the catalytic performance of mesoporous silica/alumina supported nickel catalysts for syngas production by methane dry reforming

Synthetic gas-a combination of (H2) and (CO)-is an important chemical inter mediate for the production of liquid hydrocarbon, olefin, gasoline, and other valuable chemicals. Several reforming methods that use steam, carbon dioxide, and oxygen in the presence of various catalytic systems have been extensively investigated, and this paper reviews the recent research on the state-of-the-art of reforming technologies and the effect of parameters on the catalytic activity of mesoporous silica/alumina supported nickel catalysts for syngas production by methane dry reforming. First, we provide an overview of reforming technologies, including methane dry reforming, steam methane reforming, partial oxidation of CH4, and auto thermal reforming of CH4. Then, we review the literature on dry reforming catalysts. Next, we describe recent findings on the effect of parameters on the catalytic activity of mesoporous silica/alumina supported nickel catalysts for syngas production. Finally, we make proposals for future research. This study can help achieve a better understanding of the reforming technologies and the effects of parameters on catalytic performance for syngas production, thus contributing to the development of green technologies. © 2020 Bentham Science Publishers.
