| 中文摘要 |
| 在φ100mm加压流化床气化装置上,进行了义马、大同、夏庄和南定4种煤及2种钙基脱硫剂的床内脱硫试验。结果表明,所选石灰石和白云石做为床内脱硫剂是可行的,脱硫率随Ca/S摩尔比增加而提高,比为3达最大值。操作压力对脱硫率的影响与床层温度和CO2分压有关,反应处于脱硫剂煅烧区脱硫率不受压力影响,在非煅烧区脱硫率随压力提高而降低。原煤中全硫含量增加脱硫效率提高。本试验范围所得脱硫率为50%-85%. |
| 英文摘要 |
| The data obtained from the tests indicated that both limestone and dolomite can be used effectively for capturing sulfur during the gasification of high sulfur coals. Desulfurization efficiencies can be improved with increasing the Ca/S molar ratio, the efficiencies were maximum when the ratio was 3, or by increasing total sulfur in raw coals.The effect of operating pressure on desulfurization efficiency is determined by temperature and partial pressure of carbon dioxide. The desulfurization rate was range of 50%-85% under different conditions. |
