| 中文摘要 | The recovery of biomass, waste platics and tires has important signification for energy conversation and environmental protection, the pyrolysis of these materials for liquids is a new technology. Pyrolysis is thermal degradation either in the complete absence of oxidizing agent or with such a limited supply that gasification does not occur to an appreciable extent or may be describes as partial gasification. Relatively low temperature, high heating rates and short residence time are the perfect reaction conditions. Since the Circulating Fluidized Bed (CFB) has been successfully used in many fields as an efficient, no bubble and high production capacity reactor, using the CFB as main reactor, we designed and constructed an experiment facility which included the heating, reaction, measurement and control devices. Through the cold and hot tests, we studied on the general mechanism of pyrolysis, the hydrodynamics of CFB, the characteristics of pyrolysis for liquids and the quality of product oil. This thesis consists of 6 chapters: Chapter 1. Preface The mechanism and the technology of pyrolysis for liquids were briefly introduced in this section. The relevant research in this field, the potential dominance and the developing prospect was also reviewed. Chapter 2. Experimental Facility of CFB In this section, the design and main equipment parameters of this CFB facility and the technological process were introduced. Chapter 3. The Study on Mechanism of Pyrolysis The general mechanism of pyrolysis was studied through the basic experiment which focused on the yield and the heat value of pyrolysis gas, the yield of product oil, and the relationships between them and the temperature. Chapter 4. The Cold Test of CFB Reactor In order to study on the hydrodynamics of CFB and provide the optimum operating condition and control methods for hot test, this test focused on he relationships between the solid circulating rate and gas velocity, solid inventory, L valve aeration rate, aeration point and the particle material. Chapter 5. The Biomass Pyrolysis for Liquids How the temperature, residence time and the heating rate affect the yield and the quality of product oil was studied through hot test, the ingredients of the pyrolysis oil was also analysed. Chapter 6. Conclusion and Prospect for Further Work The main results of this paper were concluded and some advises for future research work were given in this chapter. How to improve the CFB facility and upgrade the quality of product oil is the next work. |
