Preparation of an oil shale suspension in a water–mazut emulsion as a raw material for gasification

Abstract

The results of tests of the raw material preparation module of a laboratory setup for studying the gasification of a mixture of oil shale with oil residues are reported. It was shown that the equipment of the raw material preparation module makes it possible to obtain a stable water–hydrocarbon suspension of oil shale (with a solid-phase particle size of 1–100 μm). The viscosity ratio at 80°C was no higher than a required value (VR 16.0), which ensures its free pumping through the sprayers of a gasifier and a uniform distribution in the combustion chamber volume.
