Pyrolysis of Biomass Particles Using Circulating Fluidized Bed reactor with Heat loop of the Heat Carrier Particles

Salar, A.

Conversion of biomass into fuel and chemicals is currently receiving a great deal of attention because of the reduction of greenhouse gas emissions and national energy security and sustainability. The design of the pyrolysis process is important to reach higher bio-oil products and a key factor to produce higher bio-oil than char, is supplying high heat transfer rate to the biomass particles (fast pyrolysis) and fast removal of the volatiles. Although fluidized bed reactors provide higher heat transfer than conventional pyrolysis reactors, the heat transfer is limited by the convection at particle surface and conduction inside particle. The added inert particles to the fluidized bed improve heat transfer rate and fluidization properties of the biomass to reach desired fluidization velocity and good mixing of the particles. In this work, instead of using heated wall, performance of a circulating fluidized bed reactor with the heating loop of inert particles at the circulation path is investigated for pyrolysis of biomass.
