摘要：
A method for producing biochar particles or pellets which usesulphur and other additives. The method includes producing amixture with biochar and additives selected from sulphur,lignin, and gluten. The mixture is mixed with water andpassed through an extruder to produce an extrudate. Theextrudate is then cut into pellets. The pellets are thentumbled/spun with each other and heated to result in mostlyspheroidal pellets whose mechanical characteristics allow themto be used with well-known agricultural equipment. Thebiochar can be produced with sulphur incorporated as an outercoating. To produce this sulphur coated biochar, the methodincludes feeding a biomass feedstock to a pyrolysis reactor,pyrolyzing the feedstock into biochar particles, size-sortingthe biochar particles, and coating the biochar particles withthe sulphur coating material.
