Report on the brown coal liquefaction sub-committee in fiscal 1992; 1992 nendo kattan ekika bukai hokokusho

Abstract

This paper reports the activities of the brown coal liquefaction sub-committee in fiscal 1992. The first sub-committee meeting presented an interim report on the status of progress in complementary researches in fiscal 1992. The report covers the following items: discussions on effects of reaction factors on scale deposition in a preheater and a reactor and the liquefaction oil yield, supplementary experiments to enhance recovery rate of naphtha from under-flow in the de-ashing system and enhance accuracy of expression to estimate the interface precipitation velocity, and discussions on product oil types and catalyst types. The second sub-committee meeting reported fundamental discussions on the primary hydrogenation and hot water treatment of brown coal as an interim report on the achievements, and discussions on de-ashing and catalyst properties, liquefying reaction activity and scaling performance of catalysts. The third meeting reported the support on compiling the achievements by means of collecting complementary data of the pilot plant using PDU. A 7,800-hour life verification test was completed on the fixed bed secondary hydrogenation catalyst. A method was established to recover naphtha from the under-flow in a de-ashing settler. An expression to estimate the interface precipitation velocity was also established. Affirmation was made on the pylite  More>>
