Ultra-low temperature carbonization treatment method of biomass material and production method of carbide

Abstract

[Problem] To provide: a new carbonization treatment method of carbonizing biomass material containing a large amount of water at extremely low temperature, and a production method of carbide. [Solution] Keep the moisture-containing biomass material in an oxygen-containing atmosphere and at a temperature ranging from 70°C to less than 100°C without going through a drying process for the purpose of forcibly removing or reducing moisture. The aforementioned biomass material is carbonized. At this time, the moisture content (percentage) of the biomass material at the time when carbonization is started by keeping the biomass material under the aforementioned treatment conditions is preferably in the range of 40% to 80% and the aforementioned keeping is preferably 2 weeks or more. In addition, as the biomass material, it is possible to apply waste-based biomass materials selected from food waste, livestock excrement, agricultural product waste, aquatic product waste, forest product waste, and plant (cultivated crop)-based biomass materials. 1 or more than 2 types.

Description

technical field [0001] The present invention relates to a method capable of carbonizing waste-based and plant (cultivated crop)-based biomass materials at extremely low temperatures, and a method for producing carbides. Background technique [0002] In recent years, a large amount of organic waste has been composted or carbonized to restore soil as a resource. Among them, livestock dung, kitchen waste, etc. (hereinafter referred to collectively as "livestock dung, etc."), which are most expected to be recycled, often have a high moisture content and become so-called muddy at the time of generation. In particular, when livestock manure and the like are carbonized and used as agricultural resources or industrial resources, this large amount of moisture becomes a problem, and treatment to reduce moisture is required. However, in the conventional carbonization treatment equipment, waste containing a large amount of water is heated to dry it to a certain extent and then carboniz...

AI Technical Summary

Problems solved by technology

However, in conventional carbonization treatment devices, waste containing a large amount of water is heated to dry it to a certain extent and then carbonized. Therefore, a large amount of fuel for heating is consumed, and a large amount of combustion gas containing harmful substances is released to cause pollution. Atmospheric and other issues
