Fiscal 1992 survey report. Coal hydrogasification technology development; 1992 nendo sekitan suiten gaska gijutsu kaihatsu chosa hokokusho

Abstract

Surveys and studies were conducted to establish a practical SNG (substitute natural gas) production process. In the study of coal hydrogasification, a mathematical simulation was implemented to estimate the distribution of products with the pyrolytic reaction and the hydrogenolytic reaction controlled independently in the ARCH-2 (advanced rapid coal hydrogasification-2) process, the said two reactions representing the key concepts of the ARCH-2 process. It was then disclosed that a two-stage reaction control would increase the liquid yield. Also, a tentative calculation was made of gas cooling efficiency and cost performance in a process capable of achieving the target liquid acquisition rate. It was then found that BTX (benzene, toluene, xylene) production up to approximately 15% in terms of carbon was feasible and that the SNG price would be 29.03 yen/Nm{sup 3} with benzene priced at 90 yen/kg, these promising a better result than in the ARCH-1 process. The gas cooling efficiency of the ARCH-2 process was but 72.0% or less, however, which demanded improvement. Studies were made, based on the results of studies in progress since fiscal 1990, about what the hydrogasification process for Japan to develop should be. (NEDO)
