Abstract:
1. An oxychlorination catalyst comprising at least copper as an active element deposited on a support, wherein the support consists essentially of an alumina obtained by calcination of an alumina hydrate obtained as a by-product of only the ALFOL® linear primary alcohol process, wherein the ALFOL® linear primary alcohol process comprises: A. hydrogenation of triethylaluminum in the presence of aluminum metal, leading to hydrogenated diethylaluminum; B. ethylation of the hydrogenated diethylaluminum by adding ethylene, leading to triethylaluminum; C. growth reaction to build a mixture of higher molecular weight trialkylaluminums (called ethylene growth product) by further addition of ethylene to the triethylaluminum; D. oxidation of the ethylene growth product with air to the corresponding aluminum alkoxide; and E. hydrolysis of the aluminum alkoxide to a mixture of linear primary alcohols and an aqueous suspension of alumina hydrate.
