A STUDY ON SYNGAS PRODUCTION FROM DIFFERENT BIOMASS FEEDSTOCKS

The gasification process usually begins with the drying process, and then followed by pyrolysis. The pyrolysis process leads to breaking down of the biomass into solid matter, the gaseous mixture (mainly CO2, CO, CH4 and H2) and liquid matter. The main focus on biomass gasification process is to efficiently convert the entire char constituent into a gaseous product of the syngas by using either steam or CO2. The simulations include; gasification temperature, pressure, reactor volume, Equivalence ratio and moisture content have been investigated. From the result of sensitivity analysis increase the temperature the production of H2 and CO and the increase of moisture content of the biomass the lower heating value of the producer gas decrease. Based on the obtained result the maximum lower heating value of syngas was obtained at the gasification temperature of 8000C, steam to biomass ratio of 0.1 ,a pressure of 1 bar, 0.05 of moisture content and 0.02 m3 of reactor volume.
