Description
Technical field
The invention belongs to Biomass Energy Utilization technical field, more particularly to a kind of utilization wild rice stem shell is biomass combined
Fuel and preparation method thereof.
Background technology
In recent years, asked to solve a large amount of energy shortages and environmental degradation caused using fossil fuels such as coal and oil
Topic, biomass energy obtains the extensive concern of countries in the world as a kind of new clean energy resource.During the utilization of biomass energy
To obtaining high-quality fuel with as a new study hotspot by thermochemical conversion technology.
Biomass are because its is renewable, aboundresources, it is environment-friendly turn into world's fourth largest energy, be also that can uniquely transport
The defeated clean reproducible energy with storage, mainly uses the biomass energy technology of modernization that agricultural wastes, felling is surplus
The Raw material processings such as excess, feces of livestock and poultry, MSW, sanitary sewage and industrial organic waste water into biomass granule fuel,
The end products such as biodiesel, bio-fuel ethanol.Biomass fuel is almost discharged during later-stage utilization without SO2, is subtracted
The harm of the acid rain and greenhouse effects caused by the flue gas produced during its utilization is lacked so that biomass energy has more
It is wide application prospect and development space, thus Developing Biomass fuel has turned into mankind solution energy problem and improvement environment
An important means and developing direction.
China is large agricultural country, and biomass resource enriches, the yield of annual agricultural crop straw more than 700,000,000 tons, wherein can profit
Consumption is about 5.055 hundred million tons, accounts for the 50%-60% of Chinese biological matter total resources, therefore, there is important meaning to its trans-utilization
Justice.The raw materials such as agricultural crop straw have that loosely organized, density is small, distribution is not concentrated, the thermal efficiency is low, inconvenient transport and storage etc. are all
Many defects, are unfavorable for extensive utilization, and compressed biomass or extruding turn into density is larger, the thermal efficiency is high using mechanical force, just
The solid fuel stored in transport is a kind of biomass economy mode relatively advanced at present.
And wild rice stem is a kind of water plant, its hobby is warm, and moist and sun-drenched environment grows during the broiling summer
It is the most vigorous.Although wild rice stem is a kind of very popular vegetables, its shell is one of agricultural wastes.If by hay
Ultrawhite shell is used, and can both turn waste into wealth, and brings considerable economic benefit, can also alleviate and pile up or burn to ring because it is long-term
Ecological pressure caused by border.
The research with wild rice stem shell as raw material production biomass fuel domestic at present has not been reported.Therefore, for alleviate because
Burn or bury the environmental pressure that causes of wild rice stem shell, it is to avoid the wasting of resources, the raw materials such as wild rice stem shell and activated sludge are combined
A kind of biomass fuel of reproducible utilization is converted into, with considerable economic benefit and significant social effect.
The content of the invention
The present invention is to solve above mentioned problem of the prior art, proposes a kind of simple, efficiently, environmentally friendly utilization wild rice stem shell
