Biocoke producing apparatus, method of controlling the same and process for production thereof

Abstract

A biocoke producing apparatus that realizes efficient mass production of biocoke; a method of controlling the same; and a process for production thereof. The apparatus includes a horizontal tubular reaction vessel (10) provided on its one end side with a supply part (11) for biomass pulverizate and provided on its other end side with a discharge part (12). On the supply part side, there is provided an extrusion piston (6) capable of reciprocation along the longitudinal direction in the interior of the reaction vessel and capable of pressurizing the biomass pulverizate within the vessel. The temperature range and pressure range for inducing a pyrolytic or thermal curing reaction of lignin and hemicellulose contained in the biomass pulverizate are preset, and the reaction vessel (10) is provided with a thermal reaction region (13) for heating the biomass pulverizate at temperature within the above temperature range and with a cooling region (14). By means of the extrusion piston (6), not only is the biomass pulverizate transferred so as to stay for a given period of time in each of the regions but also the biomass pulverizate within the vessel is pressurized so as to fall within theabove pressure range.

Description

technical field [0001] The present invention generally relates to the field of biochar production using biomass as a raw material, and in particular relates to a biochar production facility, a method of controlling the biochar production facility, and a process for producing biochar, and the present invention is particularly capable of realizing industrial Biochar can effectively replace coke in mass production. Background technique [0002] In recent years, due to global warming, the promotion of CO 2 Emissions reduction. In particular, in combustion equipment such as utility boilers, fossil fuels such as coal and heavy oil are generally used as fuels. However, from CO 2 From an emission point of view, these fossil fuels are the cause of global warming, therefore, the use of fossil fuels will be more strictly restricted in order to protect the global environment. Also, from the viewpoint of fossil fuel emissions, there is a need to develop an alternative energy source a...

Problems solved by technology

There are still voids in the granules, which allows air (oxygen) to diffuse in the granules and shortens the burning time, and there is no bonding between the pulverized biomass, which makes the granules hard enough

[0008] In addition, according to the dry distillation method disclosed in Patent Reference 2 and other references, the treated biomass is more valuable than untreated biomass, but still has a small apparent specific gravity and a high calorific value compared to coal coke. Low
