中文摘要：

为了实现煤炭的高效洁净转化，利用自行发明的电热还原煤气化炉，以煤和石英砂为原料制备大量富含CO的燃气，同时伴生高附加值的载能材料，研究了煤种和气化工艺对燃气的组成及酸碱性的影响，并用xRD和SEM对载能材料进行测试．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燃气中CO气体的含量．载能材料是SiC，含量为98．45％，其中3C—SiC占4．12％，6H—SiC占89．81％，4H—SiC占4．42％，晶体的自形程度也比较高，多为厚板状结晶．

英文摘要：

Self-inventing multi-heat silicon carbide furnace is used in order to convert coal high-efficiently and cleanly, in which much fuel gas rich in CO is produced by using raw materials of coal and quartz. Meanwhile, high added value material is being produced. We not only study the influence of coal and gasification technology on gas products, but also test energy carrier ma- terial through XRD and SEM. The results show that fuel gas is mainly composed of carbon monoxide （CO）, the average content of CO reaches up to 70%, the average content of the COd-Hz and COd- Hzd-CH4 reach to 85% and 90% respectively. We can improve the content of CO by using an- thracite, coke or roasting method. The energy carrier material SiC （content of 98.45%） is ob- tained, among which the yields of 3C-SiC, 6H-SiC, 4H-SiC are 4. 12%, 89.81% and 4.42% respec- tively. The crystal has a relatively high euhedrat degree, most of which is thickly platelike crys- tal.
