Method for preparing molded charcoal from powdered carbon

The invention discloses a method for preparing molded charcoal from powdered carbon; a core technology comprises that biomass pyrolysis by-product heavy tar is used as a binder, the powdered carbon ismixed with the heavy tar, then the mixture is subjected to press molding to form a molded charcoal coarse blank, homogenization is achieved through pyrolysis, the problem of processing of the biomassby-product tar is also solved, and the quality of the molded charcoal is improved; combustion ash, volatile matters and other problems brought by addition of a non-wood source binder are reduced, theprocessing cost is reduced, and at the same time, the method is provided for recycling and reuse of powdered carbon used for adsorption and other uses and preparation of the molded charcoal from thepowdered carbon after coal pyrolysis. 本发明公开了种利用炭粉制备型炭的方法，其核心技术在于利用生物质热解副产物重质焦油作为粘合剂，炭粉在与重质焦油混合后经过压力成型得到型炭粗坯，再经过热解实现均质化，不但解决了生物质副产焦油的处理难题，也提高了型炭的质量，减少了非木质源粘合剂加入带来的燃烧灰分、挥发分等问题，降低了加工成本，同时也为用于吸附等用途的炭粉回收再利用、煤热解后炭粉制备型炭提供了方法。
