Abstract
The velocity of nearly spherical mono-sized PVC powder in a cold-flow rotating cone reactor (top angle π/3 rad, height 0.43 m) was measured under variation of the particle diameter (140 –780 μm) and the cone rotational speed (up to 1800 rpm). Derived residence times for these particles vary from 0.05 to 0.3 second. The gas velocity distribution near the cone wall appeared to have a considerable influence on the velocity of particles smaller than 200 μm. Next to the experimental work a mathematical model is presented, using a single-particle description and a gas-flow description near the wall according to the universal velocity profile [1]. The conversion of biomass can be calculated by combining the hydrodynamic model together with a proper heat transfer and pyrolysis model. Particles smaller than 200 μm may pyrolyse completely in the present rotating cone flash pyrolysis reactor.
