New ways to increase the depth of crude oil refining

New ways to increase the depth of crude oil refining Experimental data on thermal oxidative degradation of petroleum tar and mazut (distillation residue) are presented.

Abstract

Experimental data on thermal oxidative degradation of petroleum tar and mazut (distillation residue) are presented. Experiments were performed in a pilot installation with a continuous 1.5-L reactor at temperatures of 430–460°С and pressures of 2–6 atm with feeding air into the reactor in an amount of 30–80 L kg–1. Under these conditions, the yield of light fractions considerably increases (to 36% for tar and to 57% for mazut) as compared to thermal cracking. As in the case of thermal cracking, the cracking residue can be used as boiler fuel or asphalt. Based on the yield of hydrocarbon fractions obtained at different process parameters, the general scheme of thermal oxidative transformations of the feed was suggested, and a mathematical model describing all the experimental data obtained was constructed.
