Study of the Composition of Liquid Products of Catalytic Sapropel Hydroliquefaction

Resumo

The composition of liquid products obtained by the catalytic hydroliquefaction of sapropel was investigated. As an analysis method, a combination of currently known petroleum product analysis procedures taking into account the characteristics of the feedstock (sapropel) has been proposed. The composition of liquid products has been correlated with the solvent (decalin, ethanol) and the catalyst (CoMo/Al₂O₃, FeNi/Al₂O₃) nature. It has been shown that carboids and asphaltenes predominate in the composition of liquid products in the case of ethanol as a solvent and the concentration of paraffins and oxygen-containing compounds increases when decalin is used.
