The objective of this program is to develop the High Mass Flux Gasifier for use in the production of SNG. For this specific application a secondary coal injection stage is added to the basic oxygen-blown, entrained-flow gasifier. This addition results in an enriched methane yield and reduced oxygen and steam consumption. Specific objectives for the initial phase of development currently under contract are to: demonstrate the feasibility of the Bell HMF Gasifier as a viable reactor for efficient production of synthesis gas in a steam using bituminous coal, oxygen and steam; and evaluate the feasibility of injecting secondary coal as a means of producing a methane enriched gas. To accomplish these objectives a program comprised of the following major tasks has been defined: design and construction of a 0.5 ton of coal per hour, 15 atmosphere pressure, coal gasifier with a secondary coal injection stage; modification of the existing gasifier test facility to incorporate a pressurized slag tank, cyclone and condenser (These additions are required to facilitate collection and/or measurement of all reactor products and to effect a material balance closure); cold flow test program to develop a secondary coal injection system; and gasification tests to demonstrate the feasibility of the HMF gasifier as an efficient producer of synthesis gas and evaluate secondary coal injection. During subsequent phases of the program it is planned to evaluate methane generation at higher pressure (up to 750 psia) and to demonstrate the gasification process during continuous duration tests. Reactor and facility design tasks are approximately eighty percent completed and reactor and facility fabrication has been initiated.
