Problems solved by technology

[0011] In the existing coal slurry preparation process, due to the low metamorphic coal (R° ≤ 0.50) dissolves (melts) and expands at high temperatures in the slurry, it is very easy to form "plug flow" in the pipeline, resulting in pipeline Coking, which greatly limits the concentration of raw materials in the slurry and the safety of device operation

Abstract

The invention provides a preparation method of a coal-based heavy raw material catalysis slurry. The method belongs to the fields of a coal-based heavy raw material hydrogenation lightening technology, a coal hydrogenation direct liquefaction technology or a coal and heavy oil coprocessing hydrogenation lightening processing technology; especially relates to a heavy raw material hydrogenation lightening preposition technology unit, which is a coal-based heavy raw material catalysis slurry preparation technology unit.

Description

technical field [0001] The invention relates to the field of hydrogenation and lightening technology of coal-based heavy raw materials, and provides a method for preparing catalytic slurry of coal-based heavy raw materials. Background technique [0002] In nearly a hundred years of research on coal direct hydrogenation liquefaction methods, the research and development of coal hydrogenation catalytic reaction system has always been the main direction of coal liquefaction research and development. Due to the different formation precursors, sedimentation environments and formation processes of coal-based heavy raw materials, the organic phase of coal-based heavy raw materials has the characteristics of polycomponents in terms of composition. This is one of the main reasons for the diversity of direct hydrogenation lightening methods, and it also limits the diversity of available coal resource sources and the development of direct coal hydrogenation liquefaction methods.
