Abstract:
The biomass pyrolysis technology (carried out at moderate temperatures up to 1000˚C) allows improving of energy efficiency and workability of biomass utilization. The pyrolysis process controlling (with desired composition of products) is possible by changing the process parameters (temperature, pressure, heating rate, the biomass hold up time in pyrolysis reactor). Availability of kinetic equations linking technological parameters and vent of the pyrolysis products with biomass hold up time at preset temperature range is the necessary condition for pyrolysis process controlling. Obtaining of the pyrolysis kinetic parameters based on experimental data of the thermogravimetric analysis was the purpose of this study. Then, kinetic constants were obtained for various types of plant biomass, such as wood, corn straw, rice husk, and chicken litter, namely, the order of the pyrolysis process, the activation energy and pre-exponential factor. Obtained constants allow the reactor characteristics calculating for fixed products of pyrolysis process receiving.
