A process for the manufacture of fuel briquettes, preferably used for heating purposes, includes the steps of mixing a non-caking carbon carrier of small grain size, preferably petrol coke, with a pitch containing binder to produce a starting mixture, compressing the starting mixture to briquette blanks and producing the fuel briquettes therefrom through a solidifying heat treatment. The pitch containing binder material is preferably a binder mixture of pitch and caking coal which has a temperature of 100 to 200.degree.C. The non-caking carbon carrier is admixed with the binder mixture within the same temperature range. The briquette blanks are compressed starting at the mixing temperature. The briquette blanks are subjected to a heat treatment which has an end temperature of over 400.degree.C. Subject of the invention are also fuel briquettes manufactured using that process.
