Abstract

Butane dehydrogenation (DH) was studied on V/δ-Al₂O₃ catalysts with various surface VO_x densities by UV Raman spectroscopy to unveil the dynamics of surface VO_x and the nature of coke species under reaction conditions. Surface VO_x species were reduced to some extent under butane DH conditions. The nature of coke species depends on the structure of VO_x. Polyolefins/polyaromatics were the main coke species formed on both isolated and polymerized VO_x. 1-Butene, 2-butenes, and 1,3-butadiene were possible intermediates for coke formation in butane DH since these C₄ olefins develop similar coke species as in butane DH. This is an abstract of a paper presented at the 229th ACS National Meeting (San Diego, CA 3/13-17/2005).
