Abstract

The present invention provides a feedstock composition for increasing atomization efficiency in hydrocarbon processing comprising a hydrocarbon water-in-oil emulsion containing a non-hydrocarbon oil capable of stabilizing the emulsion and having a hydrophilic-lipophilic balance greater than about 12. Ionic surfactant. The emulsion comprises water droplets having a diameter of about 5-10 microns substantially uniformly dispersed in the hydrocarbon oil phase. These surfactants are capable of stabilizing hydrocarbon water-in-oil emulsions under the temperature and pressure conditions associated with hydrocarbon processing, and the feedstock composition of the present invention provides metastable water-in-oil emulsions in which expanding water vapor is released in a spray state at system pressure The explosion destroys the large oil droplets and produces small oil droplets.

Description

field of invention [0001] The present application relates to a hydrocarbon feedstock composition suitable for processing in a pressure-type atomizer. In particular, the present invention relates to a feedstock composition for improved atomization in hydrocarbon processing comprising an emulsified hydrocarbon water-in-oil emulsion. Background of the invention [0002] Catalytic cracking includes gas oil processing using catalysts to crack carbon-carbon bonds, especially catalytic cracking includes breaking saturated C12+ molecules into C2-C4 olefins and paraffins, gasoline, light oil, and coke. Cracking can be used to reduce the average molecular weight and produce higher yields of fuel products. Most reactions are endothermic and heat must be provided for the cracking process. Cracking can be purely thermal or thermal and catalytic. In general, it is desirable to promote catalytic cracking over thermal cracking due to the unwanted by-products produced by thermal cracking....
