Abstract

The aim of this paper is to study the air gasification of lignocellulosic biomass wastes in a fluidised bed reactor, for the production of a low Joule gas for combustion in kilns or boilers. The reactor operates on the autothermal mode. The difficulty lies in generating a tar- and carbon-free gas suitable for being substituted for imported energies, such as fuel-oil or natural gas. The experimental facility is the atmospheric pilot of Le Creusot (capacity 150 - 200 kg/h of wood). It is necessary to increase the carbon conversion yield by adjunction of a secondary cyclone to the unit. The first cyclone recycles unburnt carbon into the fluid bed, and the second cyclone eliminates ashes and fine particles of carbon. Complementary test-runs are performed on the modified unit on barks and hardwood chips, and prove the technical feasibility of the process. The description of a typical industrial gasification unit is presented, and an economical evaluation of that technique is given.
