FUELS PELLETS, THEIR PREPARATION AND USE

摘要

The invention pertains to a process for manufacturing compressed or compacted solid fuel bodies, said process comprising mixing (a) plant origin materials with (b) 0.1 -10 wt% of a starch-based binding agent, based on the total weight of the solid fuel body, and (c) a composition containing at least 60 wt% of one or more saturated long chain fatty acids having an aliphatic chain length of at least 12 C atoms, and/or analogues thereof, the weight percentage based on the total weight of said composition, wherein said fatty acids and/or analogues thereof having a melting point or melting range within the range of 40 -95 °C, wherein the weight ratio of (c) to (b) ranges between 1:200 and 1:3,and wherein the mixing of (a), (b) and (c) is performed at a temperature below said melting point or melting range, and the mixture of (a), (b) and (c) is subsequently subjected to compression or compaction at a temperature above said melting point or melting range. Stearic and palmitic fatty acids or analogues are particularly preferred.
