Carbon-mineral supports obtained by carbonization of sapropels were used to synthesize nickel-containing
catalysts. A study was performed to reveal the effect of catalyst composition (the active metal and the support
nature) on the catalytic hydroliquefaction of sapropel organic matter aimed to obtain liquid products used as
fuels. This is the first study where both the material for catalytic transformations and the catalyst support were
obtained from the same natural raw material (sapropel). Catalysts based on a support prepared from mineraltype
sapropel showed higher activity compared to catalysts with a support prepared from organic sapropel
both in the case of monometallic nickel systems and with the introduction of a second metal (molybdenum or
copper). The liquid products of hydroliquefaction included predominantly the nitrogen- and oxygen-containing
compounds (aliphatic and aromatic acids, phenols, cresols, alcohols, pyrazines, and pyridines). The nickelcopper
catalyst with support based on mineral sapropel provided a deeper conversion of the organic matter of
sapropel, with a hydrocarbon content of up to 30 wt%.
