Fiscal 1993 report on the separation/refining technology section meeting; 1993 nendo bunri seisei gijutsu bukai hokokusho

Abstract

Group activities in fiscal 1993 are reported. In the study of hydrogenation refining of the naphtha fraction under the project for 'the upgrading of coal oil and the development of oil blending technology,' a hydrogenation experiment is conducted for deheterocyclicity for in the naphtha fraction (90-180 degrees C). The neutralization process is found to greatly accelerate denitrification, multiplying the rate constant 2-5 times at 300 degrees C. In the research and development of application technologies, the ASTM-D4625-86 method is applied to the storage test of crude oils such as naphtha from liquefied Yallourn coal, kerosene, and light oil, and the results are compared with those from natural storage. It is then found that this acceleration test is applicable even to oils from coal liquefaction. In the research and development of novel catalysts, it is found, relative to the 1st-stage hydrogenation catalyst, that an increase in the amount of supported tungsten enhances the activity and life of the catalyst and, relative to the 2nd-stage hydrocracking catalyst, that YD zeolite is effective in prolonging the life of the catalyst.
