The presence of CO₂ in the syngas is attracting more attention in terms of reducing the greenhouse gas emissions in its utilisation. The aim of this study was to purify syngas from the CO₂ content of fine coal gasification. Fine coal is gasified with and without absorption using CaO, which is hydrated to Ca(OH) ₂ in the modified updraft gasifier at 450–700 °C. Apart from investigating the CO₂ absorption process, the gasification process also evaluates the influence of temperature in terms of its synergy with Ca(OH) ₂. The best conditions for the gasification process are achieved at 700 °C. The content of CO₂ was proven to be well absorbed, which is characterised by a decrease in the CO₂ content and an increase in H₂ in syngas. After the absorption process, the H₂ content obtained increased from 42.6 mole% to 48.8 mole% of H₂ at 700°C. The H₂ ratio also increased after absorption to 2.57 from the previous value of 2.23. The highest absorption efficiency of CO₂ by Ca(OH) ₂ occurred at 700°C at 50.63%. With an increase in temperature in the gasification process with absorption, the CO₂ content decreased dramatically from 16.9 mole% to 3.9%. Ca(OH) ₂ has good absorption power at CO₂ at high temperatures.
