Objective
The objectives of the proposal include:
1. Demonstration of stable and reliable operation of the existing CFB unit and identification of operating conditions to maximize the oil yield. 2. Liquid sample collection for analysis and characterisation, samples collected in a variety of operating conditions.
3. Definition of CFB reactor performance in terms of both liquid product yield and quality.
4. Investigation of the influence of the most important process parameters on CFB reactor performance and precise evaluation of mass and energy balance corresponding to the maximum oil yield process conditions. 5. Development of guidelines for improvement, optimisation and scale up of flash pyrolysis process and in particular the oil condensing unit. 6. Assessment of the gas emissions (nature and content) of micro pollutants. 7. Assessment of technoeconomics of the system, with capital cost and product estimates, incorporating sensitivity analyses for major parameters.
The major deliverables will be :
- effectivenss of the novel CFB reactor as a reliable production system for liquid fuels and/or chemicals
- identification of the best operating conditions
- modelling of the different submodules that make up the system - provision of design principles for a larger plant
- detailed analysis of the liquid products with comparison and interpretations - detailed technoeconomic assessment by undertaking
* critical and comparative review of the proposed process
* capital and production cost estimates, analysis and comparisons.
Most biomass flash pyrolysis processes are based on sufficiently high heat transfer rates to biomass particles. In this way, rapid devolatilization 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 fluidized bed reactors are usually employed. In order to best utilize the energy content of the produced byproduct char and provide the heat requirements for biomass devolatilization, char should be guided to a lower zone of the proper reactor configuration, where it is oxidized by air, the quantity of air being restricted to that necessary to carry out char combustion. The above is achieved in a Circulating Fluidized Bed.
The project includes reactor design, liquid recovery system development, technoeconomics assessment and guidelines for scale-up potential of the proposed design.
