| Description |
It is desirable to exploit biomass energy along with coal and petcoke through gasification, and understanding the differencesbetween petroleum coke (petcoke), coal and biomass gasification behaviour becomes very essential. Consequently, presentinvestigation compares gasification components of petcoke, sawdust and high ash coal with their physico-chemical propertiesunder isothermal conditions in CO2atmosphere in the temperature range of 1173–1623 K. Physico-chemical characterisationincludes proximate and ultimate analyses, porous structure analysis by Brunauer-Emmett-Teller (BET) surface area from nitro-gen (N2) adsorption isotherm, ash composition analysis and ash fusion temperature. The effects of temperature and nature ofdifferent solid fuels on gasification reactivity have been discussed. Gasification kinetics has been investigated using two nth-order kinetic models, such as homogeneous model (HM) and shrinking core model (SCM). Influence of diffusion resistance ongasification behaviour of different solid fuels is also reported. Thus, the present study will be helpful to realise the effects of highash in gasification behaviour as well as in designing and modelling of the suitable gasifier and to establish optimum gasificationconditions for petcoke, biomass and high ash coal
