Process for producing finely grained storage and transportation equipped coal or coal mixtures

摘要

1. A process for converting coal or mixtures thereof into a condition fit for storage and transport, such coal or mixture having a particle size of up to 3 mm and having been subjected to heat treatment in an O2 containing atmosphere while in a pre-dried condition without ignition occurring, characterized in that a coal containing up to 10% of volatile matter or a coal mixture composed of up to 50% by weight of one or more mixture components with up to 15% of volatile matter and a remaining coal fraction with up to 10% volatile matter, is exposed, while in an atmosphere comprising an amount of O2 equal to 12 to 21%, to a temperature between 100 degrees C and a temperature level under the coal ignition temperature or for a time of 5 to 30 seconds to a temperature exceeding the ignition temperature, the water content being set at a maximum of 3% prior to or during the heat treatment.
