Abstract
FCC dry gas contains a large amount of ethylene. It is used by most of the refineries in China as fuel or simply burned in atmosphere. Few refineries make good use of the dry gas, so the precious ethylene resource in the dry gas is wasted. In this article, the possibility of catalytic conversion of ethylene to C 3, C 4, and some high molecular weight hydrocarbons in a fixed bed micro-reactor using LTB-1 catalyst, with pure ethylene as feedstock was studied. Effects of reaction temperature, reaction pressure, and feedstock flow rate, on the conversion of ethylene and the distribution of products were investigated to determine the proper reaction parameters to be used in practice. Good results indicate that this study may provide a new way of using the ethylene resource in the FCC dry gas.
