摘要

The paper discusses the influence of the pressure of pyrolysis on the formation kinetics of C_1 -C_3 hydrocarbons, hydrogen, CO and CO_3 during pyrolysis of three selected coals of different rank. The examinations were carried out within the pressure range of 0.1 - 10 MPa under the conditions of constant residence time of primary products in the reaction zone. It was found that the pressure of pyrolysis exerts a significant influence on the formation rate of CH_4, H_2, CO and CO_2. Also, the formal kinetic parameters of formation reactions of major gaseous products during pressure pyrolysis of the examined coals were calculated.
