Gasification of Unconventional Feedstocks

Descripción

Gasification processes can accept a variety of feedstocks but the reactor must be selected on the basis of the feedstock properties and behavior in the process, especially when coal, biomass, and various wastes are considered as gasification feedstocks. The projections for the continued use of fossil fuels indicate that there will be at least another five decades of fossil fuel use (especially coal and petroleum) before biomass and other forms of alternative energy take a firm hold, although significant inroads are being made into the gasification of various feedstocks. However, the everincreasing global energy demand and the fast depleting fossil fuels have shifted focus on sustainable energies such as biomass and waste in the recent past. The importance of the gasification of such alternative feedstocks cannot be under-appreciated as potential sources of sustainable energy to meet the energy demands of future generations. The various technologies that are currently in practice at the commercial and pilot scale, with respect to bubbling, circulating fluidized beds and dual fluidized beds, are being developed for feedstocks other than coal.
