【Abstract】 A description is given of the effect of coal appropriate for coal water slurry gasification under pressure, requirements of coal quality and coal quality on the operation of the Texaco gasifier and the adaptation of choice. The process requirements of the Texaco coal gasification are discussed, and the key factors are the coal ash fusibility, corrosiveness and viscosity temperature characteristic as well as the slurrying property and reactivity of coal. Methods for coal quality assessment and optimization of raw coal exploitation are presented. A new technology is described for coal or coke blending to be used in the Texaco coal gasification process. The exploitation and testing procedure of raw coal are analyzed for the Texaco coal gasifiers at Shanxi Weinan Fertilizer Plant and Shandong Lunan Fertilizer Plant, and the exploitation experiences are summed up, thereby providing the theoretical basis and selection method for the exploitation of raw coal to be used industrially in the Texaco coal gasifier.更多还原
