Once-through methanol project support study: Final report

This report summarizes the results of a gas characterization study conducted at TVA's 200 tons of coal per day Ammonia From Coal facility under EPRI contract RP2563-3 (TV-50942A, subagreement No. 27). The main thrust of the study was to determine the levels of trace components that are potentially harmful to a methanol catalyst in unshifted synthesis gas from a partial-oxidation gasifier. The study also included an evaluation of the performance of gas cleanup equipment while using unshifted gas. Data were gathered during operation with three different coals: Utah, Illinois No. 6, and Pittsburgh No. 8. Additional data were gathered during an environmental characterization study using a western Maryland coal. 3 refs., 9 figs., 39 tabs.
