Title of Invention	"OLEFIN PRODUCTION PROCESS"
Abstract	A novel olefin production process of the invention can be established as an industrial and practical process of producing an olefin with high selectivity by directly reacting a ketone and hydrogen in a single reaction step. In particular, a novel olefin production process is provided in which propylene is obtained with high selectivity by directly reacting acetone and hydrogen. An olefin production process of the invention includes reacting a ketone and hydrogen at a reaction temperature in the range of 50 to 300°C in the presence of a Cu-containing hydrogenation catalyst and a solid acid substance.
