Processes for preparing and using high-energy biomass and biological carbon

Abstract

The invention discloses processes for preparing and using a high-energy biomass and biological carbon. The high-energy biomass comprises one type of but is not limited to high-energy biomass plant of C4 plants such as Chinese silvergrass plants, Switchgrass and the like, and the high-energy biomass plant is cultured until maturation, then is harvested and dried, and is processed by the following steps of: firstly, using high-carbon hydrate parts of the high-energy biomass plant to produce an ethanol or butanol bio-fuel by using a microbial fermentation process; secondly, drying and extruding high-fuel-value parts of the high-energy biomass plant to produce biological fuel blocks; and finally, crushing and drying other parts of the high-energy biomass plant to produce the biological carbon. The processes not only can solve the bottleneck of the conventional biomass power generation, but also can reasonably use power generation raw materials, reduce the cost and optimize the reasonable circulation of energy and carbon to achieve zero carbon emission power generation in the real sense.

Description

technical field [0001] The invention relates to a preparation and utilization process of high-energy biomass and biochar, especially a process capable of co-combustion for zero-carbon emission power generation. Background technique [0002] The use of biomass power generation has been widely used in recent years. Traditional biomass power generation mainly uses biomass such as crop straws to generate electricity directly. This kind of biomass power generation currently has problems such as difficulty in biomass collection, high cost, low calorific value, and low power generation efficiency, which severely restricts biomass power generation, a new energy industry with low carbon emissions. At the same time, in addition to the low biomass fuel value and poor power generation efficiency technically, most of the straw used for power generation has a low integration degree and ash melting point, which will seriously affect the combustion efficiency in the boiler at high temperatu...

Problems solved by technology

This kind of biomass power generation currently has problems such as difficulty in biomass collection, high cost, low calorific value, and low power generation efficiency, which severely restricts biomass power generation, a new energy industry with low carbon emissions.

At the same time, in addition to the low biomass fuel value and poor power generation efficiency technically, most of the straw used for power generation has a low integration degree and ash melting point, which will seriously affect the combustion efficiency in the boiler at high temperatures, not only causing Large heat loss, and requires special equipment support
