Field tests were conducted to research the emission characteristics and environmental risk of organic pollutants during co-processing of coal liquefaction residue (CLR) in Texaco coal-water slurry gasifier. Changes of temperature, pressure and syngas composition in the gasifier were recorded under blank condition (without mixing CLR in the slurry) and test condition (15% CLR were mixed into the slurry). Also the toxicity equivalent concentration of 16 kinds of polycyclic aromatic hydrocarbons (PAHs) and Polychlorinated dibenzo-p-dioxins (PCDDs) and Polychlorinated dibenzofurans (PCDFs) and the concentration of volatile organic compounds (VOCs) in all the solid waste, liquid and gas emissions under two conditions were analyzed. Results showed that during the co-processing process, the pressure and syngas production of the gasifier were essentially unaffected, the temperature in gasifier increased 5-11℃ and promoted the formation of H2 and CO. The concentration of PAHs in part of the gas emission, liquid em...
