Abstract:
A process for dehydrogenating an alkane to form an olefin by passing it over a catalyst comprising nickel or cobalt sulfide and cerium oxide alone or in combination with barium oxide, preferably on an alumina support, at a temperature of from about 550* to 625* C. and recovering the olefin.

Abstract:
Heavy hydrocarbon feed oils such as heavy gas oils, residium, topped crude oils and the like are hydrocracked by mixing hydrogen with the feed oil in the ratio of hydrogen to feed oil in the range from 4000 to 10,000 SCF of hydrogen per barrel of feed oil and contacting this mixture under hydro-treating conditions with a supported micro-spherical catalyst having 5-20 weight per cent tungsten and 0.5 to 5.0 weight per cent rhenium. Increased isoparaffin and aromatic content in the cracked product is obtained.
