Liquid fuels and chemicals by advanced flash pyrolysis in a circulating fluidised bed air blown pyrolyser

In the framework of a previous project under JOULE I, a novel reactor configuration for the maximisation of liquid products derived by biomass fast pyrolysis was developed. The current project focused on reactor operability, improvement and establishment of the best operating conditions. The findings reinforced knowledge on the pyrolysis of biomass to liquid fuels, and have led to substantial follow-on work. Most biomass flash pyrolysis processes are based on high heat transfer rates to biomass particles. In this way, rapid devolatilisation of lignocellulosics and the undesirable charring reactions, which otherwise prevail in low heat transfer reactor configurations, is promoted. To achieve this, either entrained flow or fluidised bed reactors are usually employed. This project included reactor design, development of a liquid recovery system, and techno-economic assessment for a potential design of circulating fluidised bed (CFB) reactor.
