| 摘 要： | 利用自行发明的多热源碳化硅冶炼炉，以煤（或焦炭）和石英砂为原料合成SiC，同时伴生大量副产品可燃性气体，研究了煤种和冶炼工艺对燃气的组成及酸碱性的影响，并对经济效益进行分析。结果表明，燃气中以CO气体为主，平均含量可达70％，CO＋H2平均含量达85％，CO＋H2＋CH4平均含量达90％，使用无烟煤、烟煤焦炭或焙烧料法可提高合成气中CO含量，若燃气用于火力发电可节约25．8％的电费成本。

| Abstract: | Using multi-heat silicon carbide furnace designed by the author themselves, synthesized SiC with raw mate- rials of coal （ or coke） and quartz, great deals of fuel gas were produced at the same time. Also study the influence of coal and smelting technology on gas composition and acidity-basicity, analyzed economic benefits. The results showed that fuel gas mainly was composed of carbon monoxide（CO）, the average content of CO reaches up to 70%, the average content of the CO ＋ H2 and CO ＋ H2 ＋ CH4 reaches 85% and 90% respectively. The content of CO could be improved by using anthracite ,coke or roasting method. ,This could save 25.8% for the generating of fuel gas. |
