Abstract

The invention relates to the technical field of clean energy, particularly to a method for increasing the content of biomass and coal in water. According to the present invention, biomass and coal aresubjected to dewatering, crushing, compression, re-crushing, and grinding and slurry preparing, such that the content of biomass and coal in water can achieve 55-65 wt% while the viscosity of the slurry is only 450-1100 mPa.s (50 DEG C), wherein the slurry has advantages of good slurry forming property, good fluidity and convenient transportation, can meet the feeding requirements of the subsequent treatment process, and can improve the utilization efficiency of the device.

Description

technical field [0001] The invention belongs to the technical field of clean energy, and in particular relates to a method for increasing the content of biomass and coal in water. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, people's demand for energy is increasing day by day, and energy and environmental issues have increasingly become the focus of attention of the international community. Coal and petroleum are still the most important primary energy in the world. With the decrease of primary energy, the quality of extracted oil and coal decreases, and the output of heavy oil and low-rank coal increases, how to develop and utilize primary energy and alternative energy more scientifically is a problem that countries all over the world are actively thinking about. [0003] Biomass refers to various organisms produced through photosynthesis using the atmosphere, water, land, etc., that is, all ...
