Preparation method of pure straw biomass type fuel carbon

Abstract

The invention relates to a preparation method of pure straw biomass type fuel carbon. The method comprises the following steps: putting crop straws (containing corn straw, wheat straw hood, rice, tree leaves and the like) in a carbonization furnace; carrying out pyrolysis and gasification reaction at the high temperature of 700 DEG C-800 DEG C; cooling the solid so as to obtain straw carbon; and carrying out gas-liquid separation on the pyrolyzed gas so that the obtained gas can generate electricity or produce methane. The straw carbon can be directly used and can fully combust without black smoke.

Description

technical field [0001] The invention relates to the field of biomass fuel, in particular to a preparation method of pure straw biomass fuel charcoal. Background technique [0002] my country is a large agricultural country, which produces more than 700 million tons of crop straw every year, accounting for about one-fifth of the world's total straw production. The use of straw in my country is basically the same as that in foreign countries. More than 50% of the straw is mainly used as fuel for living energy, and 10% The above straw is burned on the spot or directly turned into the soil and returned to the field, 30% is wasted, and about 10% is used as feed for livestock, which not only causes waste of resources, but also causes environmental pollution. With the development of the economy, my country's demand for energy is increasing. Last year, my country has become the second largest energy consumer. This situation of energy shortage has led to rising energy prices, tight po...
