Abstract
A method and composition are disclosed to reduce the oxidative deterioration of bulk materials. Preferred embodiments of bulk materials include solid fuel materials, such as coal, and bulk food products. The method includes sizing a bulk material so that it has a porosity of 40% or less. This relatively low porosity reduces the surface area of the bulk material available to the ambient environment for oxidation. The method of sizing the bulk material may be combined with the step of contacting the bulk material with an inert gas or a heat transfer medium.
