Abstract

Densification and pyrolysis are two methods to upgrade biomass. To avoid ash fusion problems, NH4H2PO4 and Ca(H2PO4)2 were chosen as additives to mix with maize straw to produce biochar briquettes. Potassium transformation mechanisms between additives and biomass in pyrolysis were investigated by XRD, XRF, SEM-EDS, and simulation. Results show that additives accelerate the production of potassium phosphates, which have potential to improve ash fusion temperatures. Addition of additive enhanced deformation temperature (DT) and softening temperature (ST). Multiple linear regression equations between DT/ST and ash compositions were established. In combustion experiment, potassium fixation ratio was increased by additives. Potassium was in the form of high melting products, which finally inhibited fusion phenomenon.
