| In China, the mined petroleum resources which per person occupies are very needy, and there are in need of nearly one hundred million tons of petroleum every year in our country. On the other hand, there are 4~5 hundred million tons various kinds of agriculture straw of pole, as well as corn hull skin 1.3~1.5 hundred million tons of the forestry bark , the sawdust, and the branches etc the surplus living creature will to be used. The purpose of this thesis mainly aim to establish a series of designing theory of the biomass energy prediction, the theory of the pyrolysis kinetics of biomass and the rotation -cone mid-temperature flash pyrolysis fluidization device which is adapt to the peculiarity of Chinese agricultural and forestry biomass, so we can proficiently and economically convert lots of wasted agricultural and forestry biomass to substitution of petroleum which is bio-oil, and provide the new technique, new theories and new method.This text completely and systematically studies the status and the development of the pyrolysis and the fluidization of biomass, which distill the bio-oil in the domestic and international area, as well as the existing problems. This thesis primarily include following aspects:(l), By experimenting and measuring the energy (heat value) and the content of C, H, N chemical element of right 20 kinds of common biomass, on the base of the experimental result, and respectively established the biomass energy predict experiment formula with the element of H and C is from change, and passed the RO.OS examination, which provides the basis and convenience for flash pyrolysis fluidization device energy to convert the rate to compute with biomass energy utilization calculation;(2), Proceeded the TG and DTG experimentation equal velocity (10癈/ min, 20 癈/ min, 40癈/ min, 60癈/ min) heating and constant temperature heating by studying on eight kinds of biomass samples, according to the experimental data and Arrhenius formula, we established the dynamics model of pyrolysis of, then, using the Goast- Redfern and P function, we also solved the dynamics parameters and analyze out every kind of biomass's frequency factor and parameters of activation energy, and established the every kind of dynamics model of pyrolysis of biomass, all of these provide the theories and basis to make sure the reactor's flash pyrolysis work temperature scope design and the describing of pyrolysis reactor dynamics; (3), In order to study and ascertain the process of heat completely getting to pyrolysis time of varied size biomass particles, we observed and measured the ratio of length and diameter (L/D) with the varied biomass through electron microscope, we concluded the L/D ratios usually is from 5.0 to 6.0, the average is 5.3 ;(4), We studied the process of biomass transiting and the theory of complete pyrolysis time with the theory of complicated heat field, we got the time (T) of the varied size biomass particles arriving to complete pyrolysis, and we knew that the complete pyrolysis time and the time which get to the biggest production ratio are identical, all of these studies provide the theorybase for design and forecasting the flash pyrolysis reactor solid state resort time; (5), According to the above experiment result, synthesize to make use of the engineering the mechanics, engineering the material, machine the design to learn the principle, deduce, establish the theory of rotation cone flash pyrolysis reactor material resort time( t) and reasonable rotation velocity(or frequency) relation theory; And (6), we gave the reactor's smallest cone angle certain, reactor cone wall strength design theory, the reactor production ability theory, the power design method and the critical rotation velocity theory.The research results provide application basic theories and foundation for the design and study of the key the rotation -cone mid-temperature flash pyrolysis fluidization device with which bio-fuel can be produced from biomass. What's more, the results provide scientific bases and pos...
