Description
Experimental results of catalytic Pyrolysis of Taiheiyo coal in a powder-particle fluidized bed (PPFB) under hydrogen atmosphere were analyzed. The catalytic pyrolysis in PPFB was considered to occur in two steps, that is, the primary pyrolysis and the catalytic decomposition of the pyrolysis product. The reaction model for the catalytic decomposition was proposed. The experimental results of hydropyrolysis of coal with CoMo-B catalyst in PPFB were analyzed by using the reaction model under the assumption of a plug flow for gas and a perfect mixing for catalyst particles in the bed. Activation energy and frequency factor of each reaction rate constant were obtained from the experimental data. Calculated yields of light aromatic hydrocarbons and gaseous products approximately agreed with experimental ones. The calculation result can be used to predict yields of tar, light aromatic hydrocarbons and gaseous products for designing this type of catalytic pyrolysis reactor.
