Process for producing solid biomass fuel

A process for producing a solid biomass fuel, wherein the process comprises the following steps:

• (i) providing one or more sources of biomass with an average particle diameter (D50) of from 30,000 μm to 60,000 μm;
• (ii) pulverizing the one or more sources of biomass to provide a pulverized biomass powder with an average particle diameter (D50) of from 1000 μm to 10,000 μm;
• (iii) drying the pulverized biomass powder so as to provide a dried pulverized biomass powder;
• (iv) molding the dried pulverized biomass powder with a compression mold so as to provide a molded biomass product with a bulk density of from 1.1 kg/L to 1.35 kg/L;
• wherein the density of the molded biomass product is controlled by using a compression ratio of the compression mold of from 3.8 to 6.5;
• (v) heating the molded biomass product to a temperature of from 160° C. to 420° C. for a time period of from 0.25 to 5 hours so as to provide a solid biomass fuel;
• and
• (vi) removing dust particles from the solid biomass fuel;
• wherein the one or more sources of biomass comprise bagasse, sunflower stalks, wheat stalks, corn stalks, sorghum stalks, soybean stalk, peanut stalks, cotton stalks, rape stalks, coconut husks, palm husks, seaweed, peanut hulls, or a combination thereof.
