Abstract

The present invention relates to the stabilization of a carbonaceous combustible solid-diesel fuel suspension by inclusion therein of wax-like polymers in an amount of at least 0.2% by weight of the stabilized suspension. The polymers preferred are homopolymers of .alpha. -olefins, and copolymers of ethylene and at least one other monomer copolymerizable therewith wherein the ethylene portion constitutes at least 60% by weight of the copolymer.
