This progress report is divided into two parts. In Part A, the results of the first three progress reports which dealt with the separation of H/sub 2//CH/sub 4/ and H/sub 2//CH/sub 4//CO mixtures resulting from coal gasification processes are briefly summarized. The separation calculations were performed for ideal, cryogenic, clathrate (gas-hydrate), and absorption/stripping separation processes. The cryogenic separation indicates the least energy requirement. Work on this phase of the program has been concluded. An experimental coal gasification program is being undertaken. In Part B, a review smmary of existing and developing coal gasificaton processes is presented. The relative merits of gasifier type, heating method, operating mode, process conditions, and gasifying medium are considered. This is followed by a qualitative appraisal of several selected coal gasification processes based upon the above considerations. It is intended that this report will help focus attention on those areas in which significant process improvements can be realized. The report concludes with a series of recommendations for future work.
