A review on sustainable synthesis of zeolite from kaolinite resources via hydrothermal process

Synthesis of zeolite through hydrothermal process has been commonly used for decades. However, it does not satisfy the serious terms of sustainability that leads to reduction of costs, reduction of waste, eliminating negative environmental impacts and improvement of any system efficiency. The bottom line of this review paper is to highlight the current trends in the hydrothermal synthesis of zeolite, attention is paid to the utilization of natural resources and manufacturing wastes as raw materials to synthesize zeolite. Optimum conditions for sustainable hydrothermal synthesis of zeolites from kaolinite natural resources are also studied and discussed in this paper. (C) 2017 The Society of Powder Technology Japan.
