This paper reports on the pyrolysis of various biomass materials. In particular, the primary yields of total volatiles, tar and non-condensable gases, together with the composition of non-condensable gases, are measured as a function of temperature. The results indicate that the pyrolysis process of wood and grass biomass (tar and gas evolution process) is greatly affected by the main composition (cellulose, hemicellulose and lignin) and the linear trends with atomic H/C ratio are observed in the tar yield, total volatile yield CO, CO_2 and CH_4 yields. The volatile yields of wood and grass biomass are predicted based only on the values of ultimate analysis of the biomass.
