Catalysis of limestone in steam coal gasification Feng, J. et al. Taiyuan Gongye Dame Xuebao, 1996,27, (4), 50-56, 60. (In Chinese) DTA in combination with GC was used to study the coal gasification in steam in the presence of JYS, XZS, DSS, and SNS limestone. The results showed that limestones have a function of catalysis on coal gasification, and JYS limestone showed the best results. No definite correlation, however, was found between the Ca/S ratio and the extent of catalysis. Soaking limestone with aqueous NaCl or NazCO, solution before using promoted the catalysis.

A cleaner technology for production of LPG + AIR for use as city gas source Han, G. and Shi, Z. Shonghui Huanjing Kexue, 1997, 16, (2), 22-23. (In Chinese) Technology for producing a LPG-air mixed gas for use as city gas was used to replace the conventional method of horizontal furnace for coal gas production.

This was beneficial to alleviating urban air pollution. The emission of SOz, NO,, and COD Mn and the contents of NHs-N, oil, and CN-in the surface water were used as criteria for assessment for the new technology.
