Akzo Nobel is an important producer of chlorine, vinyl chloride and PVC, strongly interested in a process for feedstock recycling of MPW containing PVC. Since 1994 they have chosen a fast pyrolysis process in a circulating fluidized-bed reactor, based on the technique developed by the Battelle Memorial Institute (CO, USA) for biomass gasification. 

This demonstration plant has been installed at the Zeltweg power plant operated by DRAUKRAFT (15). The BIOCOMB process is designed for preparation of biofuels for co-combustion by partial gasification and attrition due to mechanical and thermal stress in a circulating fluidized bed reactor (CFB) (Fig. 2). 

The solid circulation rate is one of the basic operating parameters of a circulating fluidized bed since it influences not only the temperature difference between the different sections of the reactor but also the residence times of particles and therefore reaction and conversiem times. For the gasification of biomass for example high temperatures are required in the gasifier for the tar pyrolysis as well as for the efficiency of the catalysts used in the pilot plant.

A pilot plant for air-blown biomass gasification in an atmospheric circulating fluidized bed (CFB) has been constructed at CIEMAT. The plant with a capacity of about 0.3 MWa, fuel input will be used to carry out gasification experiments using orujillo as a fuel. For comparison purposes, two different solid fuels will be used as the feedstocks in the gasification tests of this project orujillo and wood waste.
