Abstract
An improved process for economically converting carbo-metallic oils to lighter products. Enhanced catalyst activity is enjoyed through use of a select process to vaporize and atomize the high boiling portion of a carbo-metallic oil feed. The carbo-metallic oil feed is dispersed into droplets having a diameter of at least smaller than 350 microns and preferably 100 microns or less. These small droplets ensure more even coverage of the catalyst surface and decrease diffusion problems. The water utilized for dispersion of the carbo-metallic oil feed is present as a homogenized mixture in fine oil droplets with an average diameter below 1,000 microns. The water is dispersed in the carbo-metallic oil feed through use of a select mixing apparatus and can be dispersed as finer droplet sizes through use of an emulsifying or dispersing agent. The ratio of water to carbo-metallic oil feed ranges from about 0.04 to 0.25 by weight and the concentration of emulsifying agent ranges from 0.01 to 10 wt. % based on the weight of water.
