ABSTRACT:
Disclosed is a method to reduce oxidative deterioration of bulk materials. Preferred embodiments of bulk materials include solid fuel materials, such as coal, and bulk food products. The method includes contacting a bulk material with a heat transfer medium to reduce the temperature of the bulk material below ambient temperature, and preferably below about 10.degree. C. In this manner, the rate of oxidation is sufficiently low so that significant losses, such as the loss of thermal values in of fuel material, are avoided. The heat transfer medium can be solid or fluid and in a preferred embodiment is liquid carbon dioxide or liquid nitrogen.
