Project lignite. Final technical report, March 28, 1972-June 15, 1977
This final report describes work performed and results achieved under Project Lignite for the contract period from March 28, 1972, to June 15, 1977. It describes the development of the concept of the two-stage liquefaction of lignite, the first stage being the production of solvent refined lignite (SRL) by noncatalytic solvent hydrogenation, and the second the upgrading of the SRL by catalytic hydrogenation to a synthetic crude oil. The report covers the investigation of lignite liquefaction in a batch autoclave system, in a 50 lb/h Process Development Unit (PDU) and additionally covers a series of economic studies of the technology developed. The PDU was operated for thirty-two runs covering 1870 hours actually processing lignite under various conditions of pressure, temperature and throughput. A description of the unit is presented together with a typical material balance and yield structure.
