ABSTRACT
Biomass ash is a huge potential resource that needs to be exploration and utilization. The ash which is usually rich in silica has been used to synthesize zeolites. The aim of this work was to summarize the condition of synthesis, characterization, and application on the different types of zeolites prepared from biomass ash. In general, crystallization time (t), crystallization temperature (T) and alkaline concentration (C) were considered in the experiments. The physicochemical characteristics of zeolites were mainly analyzed by XRD, FTIR, SEM and nitrogen porosimetry. Meanwhile, the catalytic and adsorptive applications were pointed out. It’s possible to obtain the interesting information about relevant researches from this work. The mechanism of zeolite formation needs to be further clarified and reach a consensus.
