Inhibitor for inhibiting carbonaceous powder from heating up/spontaneously igniting and method of inhibiting carbonaceous powder from heating up/spontaneously igniting

Abstract

Provided as a temperature-up·spontaneous ignition inhibitor for carbonaceous powder which can inhibit carbonaceous powder such as coal and carbon blacks from temperature-up and spontaneous ignition in stacking or during storing is (1) a temperature-up·spontaneous ignition inhibitor for carbonaceous powder comprising at least one substance selected from a radical scavenger and an oxygen scavenger or (2) a temperature-up·spontaneous ignition inhibitor for carbonaceous powder comprising an amine base cationic surfactant having a hydrocarbon group having 4 to 22 carbon atoms and a nonionic surfactant. Further, provided is a temperature-up·spontaneous ignition-inhibiting method for carbonaceous powder, characterized by spraying the above temperature-up·spontaneous ignition inhibitor for carbonaceous powder on carbonaceous powder.
