The feasibility of treating petroleum coke as a secondary fuel in thermal power plants is reviewed. The pyrolysis and combustion features such as ignition, agglomeration and slagging, in addition to pollution characteristics are summarized, combining with the operation experience of a circulating tluidized bed (CFB) combustion boiler burning 100% petroleum coke in NISCO Corporation.
At the same time, the feasibility of burning petroleum coke in a CFB boiler is illustrated. The research direction on burning petroleum coke is proposed, which may provide theoretical evidence for designing and operating a CFB boiler.

Plasma reforming of natural gas to more valuable fuels Malik, M. A. et al. /. Nur. Gas C/rem., 1999, 8, (2), 166178. The most promising emerging technology for the reforming of natural gas into more valuable fuels, such as synthesis gas, methanol, ethylene and hydrogen, is the plasma process. Recent developments in this area, targeted to make the technology simple, minimize the energy losses, improve methane conversion efficiency and improve selectivity of the desired products are presented.

Plasma technique and its application in the coal synthesis gas Li, D. and Gao, J. Meitun Zhuanhuu, 1999, 22, (2), 12-15. (In Chinese) This paper presents a review of the historical development of the plasma chemical, the properties, the plasma initiation, the reactions, and application of plasma in coal synthesis gas by the low temperature and high temperature plasma gasification. It is stressed that high temperature plasma gasification of coal will become the most economic and clean way for coal synthesis gas in the future.
