TLDR
In this paper, a catalytic process is provided for converting gaseous feedstocks containing ethane to liquid aromatics by contacting the feedstock in the absence of added air or oxygen, under conversion conditions.Abstract:
A catalytic process is provided for converting gaseous feedstocks containing ethane to liquid aromatics by contacting said gaseous feeds in the absence of added air or oxygen, under conversion conditions, with a crystalline zeolite catalyst having incorporated therein a minor amount of gallium, thereby converting the ethane in the feedstock to aromatics and recovering a liquid mixture of benzene, toluene and xylene.read more
