Producer of primarily hydrocarbons , including pentanes , hexane , isobutylene , and isobutylbenzene , in technical and polymerization solvent grades , as well as several other chemicals , including mtbe and phenol derivatives -生产经营冶金焦铸造焦纯苯甲苯二甲苯工业苯中温沥青改质沥青蒽油洗油筑路油燃料油等十几种化工产品。
Contracted with rual trade limited , the third largest aluminum company in the wor ld , we exported 3000tons ' bottom cathode blocks and 10000tons ' coal tar pitch in 20 04 , which amounted near 300million us dollars 2004年，公司与世界上第三大铝业公司?俄罗斯铝业集团出口成交约3000吨阴极碳块、 10000多吨高温改质沥青，出口创汇近300万美元。
The result shows that the carbocoal produced by modified lignite under low temperature pyrolysis is a good raw material for preparing sulphonated coal ; the quality of raw materials and the temperature are the most important factors affecting the products 结果表明：褐煤低温热解改质后的半焦是生产磺化煤的优质原料，其原料性质和磺化温度是磺化煤质量的重要的影响因素。
Usage : for making pitch felt , construction waterproof course , high - grade pitch paint etc , and it is also the material for making pitch tar or retarded tar and modified pitch , it is the bond for making mould coal ( coal ball ) and carbon material , timber anticorrosion paint and road pavement 用途：用于制油毡、建筑物防水层、高级沥青漆等，也是制取沥青焦或延迟焦及改质沥青的原料,做型煤（煤球）及炭素材料的粘合剂，木材防腐油及铺路材料。
Aiming at the problems of being easy in peroxidation and low in mechanical strength in preparing sulphonated coal with lignite , feasibility of producing the sulphonated coal with lignite being pyrolyzed in low temperature and the influence of the factors such as the property of raw materials , the temperature , the time , and the size of materials on the quality of sulphonated coals were studied 摘要针对褐煤生产磺化煤存在的容易过氧化和机械强度差的问题，用正交实验法研究了褐煤经低温热解改质后的褐煤半焦生产磺化煤的可行性及原料性质、磺化温度、磺化时间、原料粒度等因素对所生产磺化煤质量的影响。
