Definitions

  • the present disclosure relates to a spontaneous heat generation inhibitor for carbon resources, a method for producing a spontaneous heat generation inhibitor for carbon resources, a method for suppressing spontaneous heat generation for carbon resources, and a method for storing carbon resources.
  • carbon resources are resources that contain carbon atoms.
  • Carbon resources are used, for example, to obtain heat by burning carbon atoms or as reducing agents.
  • Carbon resources include, for example, petroleum, coal, and biomass carbonaceous materials.
  • Biomass carbonaceous materials are carbonaceous materials obtained by dry distilling biomass.
  • Patent Documents 1 to 3 disclose technologies for suppressing spontaneous combustion of carbon resources.
  • Patent Document 4 also discloses suppressing the spontaneous combustion of coal by coating the coal with components extracted from the coal using a non-hydrogen-donating solvent. The example discloses that coal is mixed with methylnaphthalene and subjected to extraction processing using an autoclave at a temperature of 360°C and a pressure of 2 MPa.
  • Patent Document 4 is a technique in which extraction processing is performed in a limited environment, that is, in an autoclave, which is disadvantageous in terms of cost.
  • pitches for example, by-products obtained during coal carbonization
  • mixing pitches with a carbon resource can suppress spontaneous heating of the carbon resource. This is thought to be because pitches cover the particles of the carbon resource, preventing contact between the carbon resource and oxygen gas, and furthermore, donating hydrogen atoms from the pitches to the carbon resource can suppress radical reactions.
  • the production of pitches is costly, and furthermore, there is a problem in that a large amount of CO2 gas is generated during the production of pitches.
  • This disclosure has been made in consideration of the above problems, and its purpose is to provide a spontaneous heat generation inhibitor for carbon resources that can be produced at low cost and is effective in small amounts.
  • the gist of this disclosure is as follows.

  • the spontaneous heat generation inhibitor for a second carbon resource according to (1) characterized in that the first carbon resource includes at least one selected from petroleum, coal, and biomass carbonaceous materials.
  • a method for producing a spontaneous heat generation inhibitor for a second carbon resource comprising a first step of extracting a first carbon resource or a dry distillation product of the first carbon resource with hexane.
  • a method for suppressing spontaneous heat generation of a second carbon resource comprising the step of adding 1 mass % or more of the spontaneous heat generation inhibitor for a second carbon resource according to (1) or (2) to the first carbon resource.
  • a method for storing a second carbon resource comprising storing a mixture obtained by the method for suppressing spontaneous heat generation of a second carbon resource according to (5).
  • a spontaneous heat generation inhibitor for carbon resources that can be produced at low cost and is effective in small amounts. Furthermore, according to the present disclosure, it is possible to provide a method for producing a spontaneous heat generation inhibitor for carbon resources that can be produced at low cost and is effective in small amounts. Furthermore, according to the present disclosure, it is possible to provide a method for suppressing spontaneous heat generation in carbon resources and a method for storing carbon resources that use a spontaneous heat generation inhibitor for carbon resources that is low cost and is effective in small amounts.

  • 10 is a graph according to Example 2 showing the relationship between the elapsed time from the start of the spontaneous heating evaluation test and the sample temperature.
  • 10 is a graph showing the relationship between the elapsed time from the start of the spontaneous heating evaluation test and the sample temperature according to Example 3.
  • the present inventors have discovered that petroleum-based binders (sometimes called binders depending on the application) used as binders for low-quality coals are effective in suppressing spontaneous heating of carbon resources.
  • Spontaneous heating refers to heat generated in air at room temperature and atmospheric pressure.
  • Petroleum-based binders are mixtures obtained by distilling and refining petroleum. The present inventors then fractionated the petroleum-based binders by solvent extraction, and added each fraction to the carbon resource. As a result, they found that some fractions have a greater effect on suppressing spontaneous heating than adding the petroleum-based binder itself, even at the same addition rate.
  • Method for producing a spontaneous heat generation inhibitor for a second carbon resource A method for producing a spontaneous heat generation inhibitor for a carbon resource will be described.
  • a carbon resource used as a raw material for the spontaneous heat generation inhibitor will be referred to as a first carbon resource

  • a raw material is prepared.
  • the raw material is a first carbon resource or a dry distillation product of the first carbon resource.
  • the first carbon resource is a resource containing carbon atoms, and heat is obtained by burning the carbon atoms.
  • the first carbon resource is, for example, petroleum, coal, or biomass carbonaceous material.
