Title: Liquid products from pyrolysis of synthetic and natural blends of Australian low rank oil shales and lignites
Abstract: Oil shale and lignite from the Rundle/Stuart deposit and a range of mixtures of the two, have been pyrolysed in a Fischer retort. Oil yields decreased linearly from 8.67 to 5.19 wt% as the lignite content increased from 0 to 100%. Yields of gas, water and spent shale also varied linearly. HC atomic ratios of the resulting oils varied from 1.70 to 1.47 and, when plotted against oil shale percentage, a slightly concave curve resulted. Similarly, carbon aromaticity determined by n.m.r. varied from 0.33 to 0.48 and resulted in a slightly convex curve when graphed against oil shale content. It appears that oil produced by blending shale and lignite is more aromatic than expected for non-interacting components. Results show that oil from an intimate geological mixture is more aromatic than that from a comparable synthetic mixture.
