Catalytic Hydroliquefaction of Sapropels

Abstract

maximize the yield of liquid products (53%) and convert the most sapropel organic matter (74%) are determined. It is shown that liquid products of sapropel organic matter degradation contain essentially C 8--C 29 saturated hydrocarbons and aromatic and naphthenic and oxygen-and nitrogenbearing compounds in much smaller quantities. A scheme is proposed for catalytic hydroliquefaction of sapropel organic matter.Deep conversion of alternative organic feedstock sources (coal, shale oil, biomass) in order to produce synthetic liquid fuel (so-called bio-oil) and feedstock for the chemical industry is a critical thrust [1]. Catalytic hydroliquefaction accompanied by hydrogenation, hydrogenolysis, and isomerization is used to convert biomass into fuels. Solid fossil fuels in which the C:H ratio varies from 8 to 16 and the yield of volatiles per fuel mass is at least 35-36% are suitable for catalytic hydroliquefaction. The highest yield of liquid products is achieved for catalytic hydroliquefaction of slightly metamorphic coals [2][3][4].
