Catalytic hydroliquefaction of sapropels differing in organic matter and heteroatom contents in the presence of Fe 2 O 3 —Al 2 O 3 —SiO 2 , (Co/Mo)Al 2 O 3 , and (Fe/Ni)Al 2 O 3 catalysts is studied. The process conditions [(Co/Mo)Al 2 O 3 catalyst, 450°C, reaction time 1 h, and partial H 2 pressure 6 MPa] that 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.
