process for preparation of porous materials using banana leaf ash as a silicon source and application in co2 gas adsorption

摘要

The present invention relates to the process of synthesizing low cost porous materials, lta zeolite, using silicon extracted from the banana leaf ash by the alkaline leaching method and hydrothermal synthesis, and applying the synthesized lta zeolite as a co2 gas adsorber. The adsorption capacity of the high zeolite obtained was up to 2.9 mmol of co2 / g, comparable to commercial zeolites (zeolite 4a, adsorption of approximately 3.1 mmol of co2 / g). The synthesis process of this low cost material combines the eco-friendly management of solid waste from a tailings (banana leaf ash), mitigating the impact of its disposal on the soil, as well as with the control of greenhouse gas emissions. and the potential reuse of gas captured as input in the chemical industry.
