Simulation of Biomass Chemical Looping Process Based on Staged Conversion of Fuel
A new process of biomass chemical looping based on staged conversion of fuel was proposed.Through the advantages of staged conversion,high quality bio-oil and high quality syngas can be obtained at the same time,and the high volatile content and high oxygen con-tent of biomass can be fully utilized.Firstly,Aspen Plus was used to simulate the process.Secondly,the influences of pyrolysis temperature on the three phase yield,gasification tem-perature and the Biomass mass ratio(OC/Biomass)have been investigated.Exergy analysis of biomass chemical looping processes based on staged conversion of fuel was carried out.The results showed that under optimal operating conditions,the pyrolysis oil yield reached the maximum value of 54.98％,the carbon conversion rate of the gasification reactor reached 100％,the syngas flow rate reached 1.08 kmol·h-1,the gas phase product composition was stable,the system exergy efficiency is 84.45％and the product exergy efficiency is 64.98％.
