Abstract: An improved fuel, particularly an improved transport fuel composition is provided. Alternate fuels to traditional oil derived petrol and diesel have been considered particularly for transport purposes. However, there are limitations that have prevented their widespread use. A fuel composition is provided for use in an internal combustion engine comprising an organic carrier fuel having a particulate additive dispersed therein, the particulate additive being a lubricant.

Abstract: The present invention relates to a method and apparatus (10) for use in rarefying a syngas so as to improve a calorific value of the syngas through the reduction of a concentration of tar from the syngas. The apparatus (10) comprises a gasification/pyrolysis means (12) such as a kiln (11), for generation of a flow of syngas from a raw material, and a cracking means (14). The cracking means (14) comprising a body (42) having an insulated internal volume (44) adapted to hold a heated bed of char. The flow of syngas from the kiln (11) is directed through the cracking means (14) where it comes into contact with the heated bed of char. Heavy long-chained carbon based molecules within the syngas undergo a cracking reaction and are broken into constituent lighter carbon based molecules. The method and apparatus of the present invention provides a rarefied output flow of syngas having an improved calorific quality and a substantially reduced concentration of tar.
