Description:
Coal gasification test runs have been conducted in a semibatch, fixed-bed laboratory gasifier in order to evaluate various coals and operating conditions for pollutant generation. Thirty-eight tests have been completed using char, coal, lignite, and peat. Extensive analyses were performed for organic and inorganic compounds and trace elements in the tars and hydrocarbon oils, aqueous condensates, and reactor residues resulting from the gasification tests. Over 300 compounds were identified from the various gasifier streams, and more than 100 of these compounds were quantified for several of the test runs. Statistical analyses have been performed on the data. The quantity and composition of the various effluents have been examined in relation to coal type and operating variables. Results are reported for sulfur species in the product gas stream, for consent decree pollutants contained as volatile organic compounds in the product gas, for phenol and related compounds in the aqueous condensate and tar/oil sample, and for polynuclear aromatic hydrocarbons (PNA) species in the tar/oil.
