摘要
氢能是一种高效洁净、理想的、极有前途的二次能源。“绿色煤电”计划将建立2MW的氢能试验系统,进行煤气变换制氢、氢能发电、CO_2利用的试验研究。介绍2MW氢能发电试验系统的设计方案:煤气化工艺采用西安热工院的两段式干煤粉加压气化技术,CO变换工艺采用中温耐硫变换工艺,脱碳工艺经比较采用变压吸附工艺,提纯的氢气用于高温燃料电池发电和氢燃气轮机的燃烧试验,CO_2作为商品销售。煤气变换提纯后CO_2体积分数小于0.2%,H_2体积分数大于99%,燃料电池发电效率达60%以上,系统CO_2达到零排放。煤制氢及氢能利用技术具有广阔的应用前景。
Hydrogen energy is high efficient, clean and ideal secondary energy with bright prospect. The GreenGen Project plans to set up a 2 MW hydrogen power test system, on which the technologies of hydrogen conversion by coal-gas, hydrogen power generation and CO2 utilization can be done. The design scheme of 2 MW hydrogen test system was introduced as： the two-stage pressurized entrained flow gasifier with dry feed was used in gasification, the sulphur-resisting technique was used in CO conversion, the pressure swing adsorption technique was used for de-carbon process and purified hydrogen was used for the high temperature FC power generation and the combustion test of hydrogen gas turbine with CO2 as commodities to sell. After purification, the volume fraction of CO2 is less than 0.2%, H2 more than 99% and the efficiency of FC power system is more than 60% with zero emission of CO2, The technologies of hydrogen production from coal and hydrogen utilization are of wide application prospect.
