Alternative to visbreaking or delayed coking of heavy crude oil through a short contact time, solid transported bed cracking process

Abstract

An extra-heavy crude oil was treated at short contact time in the 510-580°C temperature range in a FCC-like process, first thermally and then in the presence of a solid with low catalytic activity. The treatment improved greatly the properties of the crude oil, reducing density and viscosity to values that makes the oil transportable without dilution in pipeline. Besides, the upgraded was substantially free of contaminants such as metals and heptanes insolubles. The use of the solid allowed upgrading all properties with a minimum coke penalty. The residual fraction of the upgraded oil had to be eliminated to obtain a syncrude stable in asphaltene proof, which could be obtained by recycling to extinction in the cracking reactor.
