摘要： High purity acetylene gas is provided by discharging high purity acetylene gas from a metallic bomb in which a porous material to accommodate high purity acetylene gas and a solvent to selectively dissolve the acetylene gas are charged and passing the gas through an adsorber containing an adsorbent for adsorbing the solvent contained in the gas. Superfine powders of impurities are removed by passing the gas through a filter. Acetylene is purified by adsorbing acetylene into a solvent having a temperature of -20.degree. to -81.8.degree. C. in an absorbing tower, stripping the acetylene from the solvent at a temperature of -10.degree. to +20.degree. C. in a stripping tower and passing the stripped acetylene through a packed bed filled with a porous material for removing impurities from the acetylene and through a filter for removing superfine powders of impurities. The inside of a bomb for dissolved acetylene is purified by heating the bomb and evacuating the bomb. A bomb for acetylene charged with a solvent which selectively dissolves acetylene is filled with high purity acetylene gas by thermostatically controlling the temperature of the bomb at a low temperature and filling the bomb with acetylene gas without the use of pressure.
