THE CRACKING EXPERIMENT RESEARCH OF TAR BY CAO CATALYST
The tar from rice husk gasification for power generation was taken as an example to be catalytically cracked by CaO catalyst. The experimental results showed the cracking efficiency of tar greatly increased from 28.66％ by thermal cracking to 65.6％ by catalytic cracking, the gas compositions from tar being cracked were H2, CO, CH4, and CO2, and the H2 was a majority of them. The DSC and XRT analysis revealed that the deposit carbon could be found after tar was catalytically cracked and the deposit carbon efficiency could reach 30.51％. The SEM photographs of CaO catalyst used as catalyst showed that the CaO catalyst was enwrapped by the deposit carbon and decreased its catalytic activity, at the same time, the pressure drop of gas passing through catalyst bed increased because of the deposit carbon, it was different for us to operate the cracking reactor of tar and CaO catalyst in the cracking reactor must be regenerated for its stable operation.
