  • In every thermal upgrading process, short-chain hydrocarbons contain a part of the gas byproducts. These compounds are hydrogen-rich materials, which are considered as low value wastes. In this study, the efforts were made to catalytically convert these off-gases to liquid fuels. Synthetic gases were used as model reactant gases. Four types of zeolite including ZSM-5, Mordenite, Ferrierite, and Zeolite Y were tested. Among these catalysts, ZSM-5 was the most active one for alkene conversion. At adiabatic condition, it had the capability of producing aromatic compounds. Performance of four types of nickel incorporated catalysts including ZSM-5, two kinds of silica-alumina (with 20 wt.% and 40 wt.% SiO2), and silica were also investigated for this purpose. Among these catalysts, reduced form Ni (on silica) exhibited significant dehydrogenating activity for butane. ZSM-5 had the capability of making cyclic compounds, while silica-aluminas mainly had nickel aluminate in their framework.
