温度对天然焦蒸汽气化特性的影响
Influence of temperature on natural coke-steam gasification characteristics
摘要
Abstract
Steam gasification characteristic of Peicheng natural coke is studied in a bench-scale fluid-ized bed (φ50 mm, 1.6 m). Effects of the operation temperature on the gas yield, carbon conversion, heating value and gas components are discussed. Experimental results are also compared with those of ASPEN PLUS simulation. Experimental results show that gasification temperature is a key parameter. As the temperature goes up, the contents of H_2 and CO_2 in the product gas decline while the content of CO increases. As the gasification temperature rises from 850℃ to 1 000℃, the volume fractions of H_2, CO, and CO_2 in the product gas change from 63. 0% , 25. 0% , and 9. 6% to 59. 8% , 20. 2% , and 18. 5% respectively. Product gas yield increases by 4. 3 times and carbon conversion rate gets increased from 10. 25% to 47. 76% , and the gas heating value increases from 8. 87 to 9. 33 MJ/m~3. The ASPEN PLUS simulation results accord well with the experimental data when the carbon conversion rate is selected according to the experimental results.关键词
