The thesis is based on the optimization of one-step synthesis of glycidol from glycerol in the gas-phase packed-bed continuous flow reactor at atmospheric pressure. CO$_2$ was used as the carrier gas. The catalysts were characterized by XRD, BET, TGA and SEM. The reaction was carried out under different Cs loadings of catalyst, reaction temperatures, catalyst weights and CO$_2$ flow rates. The most optimal conditions for the reaction are 0,25 g of 35 % Cs/ZSM-5(1500) catalyst at a temperature of 550 °C and a moderate CO$_2$ flow rate (40 ml/min). The highest glycerol conversion achieved under these conditions is 86,6 mol%, the highest glycidol selectivity is 63,8 mol%, the highest yield is 51,9 mol% and the highest STY value obtained is 12,5 mmol/g$_{kat}$/h.
