Co-pyrolysis of biomass woodchips with Ca-rich oil shale fuel in a continuous feed reactor

A co-pyrolysis of woodchips and oil shale was conducted in a continuous reactor at 520 degrees C in a CO2 2 atmosphere. Experimental product yields were derived and an analysis of the liquid products was conducted, using gas chromatography, infrared spectroscopy, and physicochemical analysis. A maximum yield of liquids and gases was obtained as the share of biomass increased (43.9 and 35.1 wt%, respectively). Product characterization confirmed additive behavior in co-pyrolysis. The liquid products from co- pyrolysis blends exhibited fewer oxygenated compounds, derived from biomass, and fewer aromatic compounds, derived from oil shale. Co-pyrolysis liquids contained abundant aliphatic hydrocarbons (C6 6 to C11). 11 ).
