The Studies Of Biomass Solidifying Technology And Principle With High Pressure On Natural Conditions For Bio-fuel Making

Energy crisis and environmental pollution are common problems faced by the world, the whole world has taken the reproducible energy development as an important task. The interior configuration and characteristic of the biomass are similar to coal and petroleum, so it can be dealt with and utilized by the same or similar technique, which can make it easier to exploit and popularize. Used advanced technique, high-quality reproducible energy would be translated from biomass. Biomass solidifying technology has the merits such as processed easily, cost low, deposited and transported facility, good combustibility and high thermal efficiency. The bio-energy would have great prospect in the countries which are deficient with petroleum and coal.The purpose of this study is finding out the parameter scope of solidifying factors, and groping for solidifying principle, which take energy efficiency, low-cost as springboard. All the studies we have done would provide theoretical basis for equipment design and optimization of process parameters, and be advantageous to the commercialization of bio-fuels. The main content and conclusions drawn in the dissertation as follows:1. Chose the main body of biomass solidifying technology with high pressure on natural conditions though comparing aspects of productivity, energy consumption, cost and operating environment. At last, chose the hydraulic pressure urged piston solidifying machine.2. Compressed five different materials in different pressures though solidifying experiment in high pressure and natural conditions, drew out the briquette density versus pressure, elicited quantitative relation; compressed the materials of sawdust and small paring in different moisture content and pressure, educed the relation between moisture content and briquette density, analyzed the results and gain the conclusions: the material with moisture content of 15% can be compressed with the biggest density, the limited moisture content which the equipment can process is 22%, considering from...
