| Abstract |
The development of coal gasification has several disadvantages including high reaction temperature and big energy consumption, difficult purification of the gaseous products, and stringent requirement...s of the process equipment. It has also been pointed out to cause serious environmental pollution. To overcome these problems, the coal catalytic gasification technique can improve the reaction rate and conversation efficiency compared to conventional gasification techniques. In this study, the experiment was conducted by flowing nitrogen, oxygen, and steam, into the gasification equipment. The gasification reactor was heated to 600℃and 800℃, where dry coal had been initially fed into before the gasification process began. The flow rates of pyrolysis products were then measured and a sample was taken for further analysis by using a gas chromatograph. The analysis identified the products composition that was CO, CO_2, H_2, CH_4, C_2H_4 and C_2H_6. The experiments that used K_2CO_3 as a catalyst were conducted by feeding the catalyst into the reactor. After the catalyst started to react, the coal was slowly fed. The composition of synthesis gas was observed to depend on the gasification agent used. Based on the experiment of synthesis gas production from Indonesian low-rank coal and catalyst K_2CO_3, it can be summarized that there is a good correlation between gasification agent, coal and catalyst used, with the quality and quantity of synthesis gas produced.show more
