Abstract

Liquid products of the autoclave hydrogenation and hydropyrolysis of the Barzas sapromixite were studied. Chromatomass spectrometry was used to determine the content of individual substances in the low boiling fractions. Hydropyrolysis product appeares to consist of normal paraffins by more than 50 mass %. Hydrogenation products is characterized by a higher content of cyclic and structure isomerized paraffins. Aromatics content in both products does not exceed 14.1 mass %. IR and NMR spectroscopy show that fractions boiling above 180 oC contain mostly aliphatic fragments. Hydropyrolysis products composition is similar to that of oil, while hydrogenation product is characterized by more aromatic and shorter aliphatic fragments per statistically average molecule. If mechanically activated iron ore catalyst is used at the sapromixite hydrogenation and hydropyrolysis, the contribution of distillate fractions increases, and low boiling (boiling start 180 oC) fractions contain more low molecular mass hydrocarbons.
