摘要

Thermochemical conversion is the main route to utilise various solid fuels such as coal and biomass. The typical thermochemical processes include pyrolysis (carbonisation), gasification, combustion and liquefaction. In each of these conversion processes, not a single but a series of reactions occur to constitute a complex network of chemical reactions, which sometimes are further complicated by various heat and mass transfer processes. These chemical reactions are mutually interactive and inter-connected, particularly through the formation and consumption of many types of radicals. The extent of these interactions can also be affected by the physical processes. A set of reaction conditions favouring one reaction or one type of reactions may not be ideal for another reaction or another type of reactions in the same thermochemical conversion system. To optimise the overall thermochemical conversion process, e.g. to enhance the overall rate or to maximise the overall process efficiency, it often becomes necessary to manipulate the interactions between/among the various chemical reactions or reaction groups involved in the same thermochemical conversion process.
