The major challenge in the current context of a rising world’s energy demand is to limit global temperature increase for mitigating climate change. This goal requires large reduction CO2 emissions, mainly produced by power generation and industrial processes using fossil fuels. In this study, novel methodology K2CO3-doped Li4SiO4 sorbents production capture at high was adopted based on Design Experiments (DoE). Different synthesis (temperature K2CO3 content) adsorption conditions (sorption concentration) were systematically tested Response Surface Methodology (RSM) obtain predictive models uptake conversion. results RSM analysis evidenced maximum capacity 196.4 mg/g sorbent 600 °C with 36.9 wt% K2CO3, 500 4 vol% CO2. Whereas 50 CO2, best 295.6 obtained synthesized °C, containing less (17.1 wt%) higher (662 °C). highlight that can be tailored maximizing different operating conditions, making them suitable use processes.
