The Crucial Role of the Process Modelling During the Design of a Bubbling Fluidised Bed Gasifier of Plastics

Gasification is a thermochemical process that aims to convert solid fuels into a synthetic gas that can be addressed to an end-use apparatus to produce electric energy and heat or can be further refined to be transformed in chemical valuable products. Many solid fuels, included waste (wood, biomass, plastics, municipal solid waste, etc.), can be gasified under different operating conditions (pressure, temperature, reactants) in different kind of reactors. This paper aims to correlate the descriptive model for the gasification of a mixture of commodity plastic waste to the basic design of a bubbling fluidized bed gasifier on the basis of experimental data and mathematical calculations.
