More Information
Summary:A propane production method includes a hydrogenation reaction step of hydrogenation-reacting crude propylene and hydrogen in a presence of a catalyst to obtain gaseous crude propane containing impurities; and an impurity removal step of removing the impurities contained in the gaseous crude propane obtained in the hydrogenation reaction step to obtain purified propane. The impurity removal step includes an adsorptive removal stage of adsorbing and removing water, ethane and propylene contained as impurities in the gaseous crude propane by adsorption treatment in which the gaseous crude propane is brought into contact with an adsorbent, and a separation removal stage of separating and removing hydrogen, oxygen, nitrogen and methane contained as impurities in the crude propane after the adsorption treatment by partial condensation or distillation of crude propane after the adsorption treatment in the adsorptive removal stage.
