Coal pyrolysis produces a variety of products. Therefore for a reasonable design of an economical process, it is essential to have a detailed planning how to properly use all the products. We have been investigating the method to control the product distribution. The present study attempts to obtain basic pyrolysis data under a high pressure hydrogen with a continuous coal feed. It was found that the pyrolysis temperature, residence time and catalyst have large effects on the hydrocracking reaction.

The fracture analyses for coke models reproducing the form of the non-adhesion grain boundaries were performed using the rigid bodies-spring model. The coke model was developed by the random arrangement of the coal particle polygons and expansion of the polygons based on experimental results. As a result, many springs at the gap or edge of the non-adhesion grain boundaries were fractured, and the arrangement and shape of the non-adhesion grain boundaries were supposed to affect the fracture of the coke. Furthermore, the coke with the larger blending ratio of the low-quality coal fractures with the weaker strength. This is because the number of the non-adhesion grain boundaries increases, and the size of the boundaries becomes larger and the shape of the boundaries becomes complex.

The need for power to gas system is increasing according to the increase of power generation by renewable energy. Heat and mass balance of the coal gasification methane production system was analyzed aiming to integrate with the power to gas system which utilizes methane as a storage medium. The system converts 500 ton/day of coal to 141 ton/day of methane and conversion efficiency is 64.9% in calorie basis. Suppose surplus electricity is 10 MW, 7.8% of coal and 12.9% of oxygen can be saved by the integration. Surplus water recovered from the outlet of shift reactor and water generated with methane at the methanation reactor is recycled to the gasifier outlet to increase H_2O/CO ratio of syngas. This direct quench method contributes to reduce the plant cost because water can be recycled without water treatment.

In the hydrogenolysis of trans-stilbene under nitrogen at 380℃, coal liquefaction residues (CLR) act as duplex hydrogen transfer agents donating their inherent hydrogens and shuttling ones from hydrogen donor solvents.

The direct synthesis of carbon nanotube (CNT) from coal was examined by chemical vapor deposition (CVD) method. Under selected conditions including the reaction temperature and the amount of catalyst, CNT production from coal was successfully achieved. Based on the results of the experiments with several coal samples, the effect of the production conditions on the yield and property of CNT was discussed.
