FY 1981 Report on the results of Sunshine Project. Coal energy; 1981 nendo sunshine keikaku seika hokokusho. Sekitan energy

Abstract

This report presents the results of (researches on solvolysis liquefaction mechanisms and reaction promotion with oil- and coal-based solvents), conducted as part of the research and development project for coal liquefaction techniques. The FY 1981 program includes researches on (1) the effects of liquefaction reaction conditions on liquefaction yield and production of light products for coal species of low degree of carbonization, including brown coal, (2) the effects of pretreatment of coal on its liquefaction reactivity, and (3) up-grading of the solvolysis coal liquid (SCL). For the item (1), HA240 (hydrogenated Ashland's A240) is used to investigate its liquefaction capacity for various coal species of low degree of carbonization, including brown coal. For the item (2), the effects of pretreatment in a hot water bath with reflux was investigated for sub-bituminous coal in the FY 1980. In the FY 1981, various pretreatment methods are attempted for enhancing liquefaction reactivity of brown coal. As a result, it is found that ash content of brown coal is decreased to one-third of the initial level, when it is treated in a diluted hydrochloric acid bath with reflux. For the item (3), SCL hydrogenated by Birch reduction (B-SCL, 1) is compared with H-SCL with  More>>
