Development of NaY zeolite derived from biomass and environmental assessment of carbon dioxide reduction

摘要

Carbon dioxide is one of greenhouse gases. The carbon dioxide caused by the industry activities and impact to the global warming. The objectives of this research were to synthesize NaY zeolite from bagasse ash as silica source and loaded with different weight percentage of Cu(II) for carbon dioxide reduction. The carbon footprint of Cu/Y zeolite for carbon dioxide reduction was calculated. The synthesized NaY zeolite from bagasse ash can be easily formed at Si/Al ratio of 0.75 with the additional heat after crystallization 70 °C for 1 hour. The crystal size of NaY zeolite was approximately 0.22?0.37 μm diameter. The results of carbon dioxide adsorption were increased when the flow rate of carbon dioxide decreased. Finally, the carbon footprint value was shown that synthesis step was shown the highest of greenhouse gas emission. This research can increase the value of wastes and reduce pollution emission.
