    摘要： Biofuel composition comprising waste coffee grounds (WCG). It is preferably solid, formed as briquettes, pucks or pellets, the pellets being suitable for combustion in a biomass boiler. Preferably it comprises at least 50% wt WCG, even more preferably at least 75%. At least half of this quantity is preferably made up of waste coffee grounds from the manufacture of instant coffee (IWCG). The biofuel may additionally contain a fibrous filler (sawdust, coffee bean husks), preferably less than 50% wt, and a binding agent (lignosulphonate, glycerol), preferably up to 10% wt. Other possible ingredients are oxidisers like sodium / potassium nitrate and processing agents like starch (also a binder). The biofuel preferably has a durability of at least 60% and a net calorific value of 16-24 MJ/kg. A method of producing such biofuel is also claimed, by compressing suitable feedstock into pellets etc. The WCG may be dried to a moisture content of 6-20%. Coffee oil is preferably extracted therefrom, then the WCG are mixed with other ingredients and the feedstock may be conditioned through treatment with steam, then pressed / extruded through a die having boreholes into pellets which are further cooled. A relevant apparatus is also claimed.

    摘要： A process for torrefaction of biomass is provided in which biomass and fluidizing gas are added to a fluidized bed reactor, wherein the fluidizing gas comprises a gas from the fluidize bed reactor and air, wherein the gas leaving the fluidize bed reactor has an oxygen content of less than 8 volume percent, wherein an oxygen content of the fluidizing gas is between 10 volume percent and 14 volume percent, and wherein the oxygen content of the fluidizing gas is adjusted with the air; wherein said biomass is heated by increasing the temperature of said fluidized bed reactor; wherein said biomass is maintained within said fluidized bed reactor for a predetermined time, wherein water is removed from set biomass; wherein volatile organic compounds associated with said biomass are vaporized; wherein the biomass is combusted with the oxygen in the fluidized gas added to said reactor and said biomass is torrefied; wherein said volatile organic compounds are combusted to help maintain the temperature of said fluidized bed reactor; and wherein the torrefied biomass is formed into pellets at a temperature of 90 °C to 200 °C.
