Abstract The project is one of the sub-guant projects in the second round of biomass competitive grant activities at the national level, which is held by Wu Youqing of ECUST. The project objective task is to research and develop the prototype of the industrial-scale catalytic cracking devices of biomass tar. The project mainly carried out the industrial technology research and development of the catalytic cracking behavior, process conditions, device structure properties and conversion rate, etc., which can solve completely many problems, such as the tar damage to the reliable operation of process equipment faced by biomass thermal chemical processes generally, the efficiency reduction of biomass conversion, the destruction of the surrounding environment, the hard effective use of itself, and so on. The study of the project has formed the efficient and clean biomass tar cracking equipment and the core technology of catalyst formulations with independent intellectual property, by which the efficient and clean biomass thermo-chemical technology without tar can be promoted to improve. The project is currently underway.

Development of Briquetting Machine Model BCYK

Abstract It is one of the sub-grant projects in the second round of of National Biomass competitive grant activities. It is planed that the project develops the biomass briquetting molding prototype with low energy consumption at normal tempreture, through reasearching the two core technologies of the formation of power transmission and molding module. The prototype changes the traditional “compression molding with positive pressure at high temperature ” to “grind molding with partial tensor at normal temperature”, which solves the problems of “poor force conductivity” and “high moisture” of the biomass raw materials of straw type from the mechanism, and reduces the pressure and energy consumption needed by molding radically. The molding machines improve effectively the stability of the equipment and extend the working life of the core components. The project is currently underway.

High-efficiency and Low-cost Equipment of Biomass Pellet Molding

Abstract It is one of the sub-grant projects in the second round of National Biomass competitive grant activities. Through the research on the physical and chemical properties of biomass materials, and the optimal design of the molding key components, such as the roller, ring mold, feeding devices, etc., the PM485-Ⅱ high-efficiency, low-cost, solid biomass pellet molding machines were developed. The service life of key components is increased. And the problems of low productivity, high energy consumption per unit, poor adaptability of raw materials and so on were solved. The project is underway currently. By December 2010, the model products had been popularized and applied in Heilongjiang, Hebei and other places. Five production line of in biomass pellet fuel had been established in Guyuan of Hebei, Bin County of Heilongjiang and other places with the annual production capacity of 100 thousand tons and the profit of 5 million yuan RMB.

Completed Equipment Development of Power Generation by Circulating Fluid Bed Straw Gasification

Abstract It is one of the sub-grant projects in the second round of state-level biomass competitive activities. The project aims to design a large and complete biomass circulating fluidized bed pyrolysis process system, including the biomass pyrolysis device, gas purification system, waste heat recovery system and flue gas purification system to carry out the demonstration construction, through improving the existing technologies. The pyrolysis process of fluidized bed is working at high temperature, uniformly and stably. While the straw pyrolysis gas is used for generating power, it cracks tar, which improves the straw utilization efficiency and gas quality. The technical support unit is the Department of Thermal Engineering of Tsinghua University, and the equipment manufacturing unit is the Tangshan Xinde Boiler Group Co., Ltd. The project is currently underway.

Biofuels in the Greater Mekong Subregion

Abstract In the Greater Mekong Subregion (GMS), a growing demand for biofuels could help support the agriculture sector and provide an alternative source of energy. However, if deployed unsustainably, biofuels development can be associated with numerous risks that have negative ramifications for human development. This paper reviews existing literature and integrates various themes to provide an overview of four main issues related to biofuels deployment in the GMS: the need for alternative energy, risks to food security, considerations for environmental management, and opportunities for rural development. This paper was prepared as a discussion piece for the GMS 2020 International Conference (20–21 February 2012 in Bangkok, Thailand).

Rural Biomass Energy 2020 in the People’s Republic of China

Abstract This publication explores the potential of biomass energy to close the urban-rural energy gap, raise farmer incomes, and address some of the environmental concerns in the People’s Republic of China (PRC). Its findings are useful for other developing and medium-income countries currently in the process of drawing up their respective energy-for-all strategies. The report examines the promises and limitations of leading biomass energy technologies and resources for various distribution scales, including but not limited to household biogas digesters. The information is based on lessons learned and experiences from the ADB-financed Efficient Utilization of Agricultural Wastes Project in the PRC, as well as findings and conclusions from a technical assistance grant to assist the government draft a national strategy for developing rural biomass energy.
