Abstract:
     The present invention discloses a method for preparation of type C compound ammonium bicarbonate additive. It is made using C12-C18 alkyl benzene sulfonic acid or sodium (C12-C18) alkyl benzene sulfonate or pentadecyl sulfonyl chloride as basic raw material, stearic acid as main raw material, ordinary diesel as promoter through dissolution in specified proportion, mixing, heating, agitating and saponification with aqueous ammonia into emulsion. The said additive can effectively prevent carbonization system from foaming and liquid entrainment, increase significantly nitrogen content of ammonium bicarbonate, reduce water content, avoid agglomerating, stabilize carbonization conditions, and increase separation effect of centrifuge.
