267 Tons of delayed petroleum coke were gasified in an air-blown, fixed bed coal gasifier as part of an on-going industrial coal gasification test program. Two size distributions of double screened petroleum coke were tested during a total of 17 days of operation. The gasification test allowed measurement of fuel gas quality and conversion efficiency as a function of load and steam/air ratio in the gasifier blast. The results of the test indicate that petroleum coke is an excellent fixed bed gasifier feedstock. The negligible ash content provides for very stable and labor-free operation. The primary technical (and perhaps economic) drawback is high sulfur emissions when a high sulfur petroleum coke is used. Preliminary economic analyses indicate that the fuel gas is an attractive replacement for natural gas or oil.
