Conclusions 1. A silica gel — chromium catalyst with a low amount (0.3%) of chromium is reduced more completely in a reducing atmosphere, and then is oxidized more completely in an oxidizing atmosphere, than is an alumina — chromium sample with the same amount of chromium. 2. When compared with the alumina — chromium sample, the higher dehydrogenation and dehydrocyclization activity of the silica gel-chromium catalyst is caused by the greater amount of surface chromium ions, including Cr2+ ions, in it.
