    摘要： A solid form adsorbent of carbon monoxide, that is obtained by the process including the following steps. First, copper salts or copper oxide is stirred in a solvent. Then, into the solution or suspension thus obtained, active carbon is added. Finally, the solvent is removed by means of pressure reduction, distillation, etc. The carbon monoxide adsorbent produced according to this invention adsorbs carbon monoxide rapidly when it is brought into contact with a mixed gas. The adsorbed carbon monoxide can be readily separated and discharged through either heating the carbon monoxide adsorbent to above 60.degree. C. or reducing the partial pressure of carbon monoxide. The carbon monoxide obtained in accordance with the present invention is stable relative to the water content in the mixed gas, and it is capable of separating carbon monoxide directly from the mixed gas containing the water. Also, the separated carbon monoxide does not contain the vapor of the solvent from the carbon monoxide adsorbent. Therefore, it is not necessary to provide equipment to collect the solvent vapor. Furthermore, this carbon monoxide adsorbent does not produce corrosive gases, etc. The carbon monoxide adsorbent obtained by using copper (II) salts or copper (II) oxide is also stable relative to sulfur content in the mixed gas.

    摘要： Disclosed is a method for preparing a non-aqueous dispersion of particles of a metal and/or a metal compound, which comprises contacting an aqueous dispersion of particles of a metal and/or a metal compound with a water-immiscible, non-aqueous liquid in the presence of a surfactant and in the presence or absence of a water-soluble inorganic acid salt and/or a water-soluble organic acid salt exhibiting substantially no surface activity, wherein when the contacting of the aqueous dispersion with the non-aqueous liquid is conducted in the absence of the salt, the salt is added after the contacting, thereby causing the particles to be migrated from the aqueous dispersion into the non-aqueous liquid.

    摘要： A solid adsorbent for an unsaturated hydrocarbon including (a) (i) a copper(I) halide or oxide or (ii) a halide, carboxylate, sulfate, basic salt, oxide, or amine complex salt of copper(II) and (b) activated carbon or graphite is described.This solid adsorbent can effectively adsorb an unsaturated hydrocarbon such as ethylene from a gas mixture by being placed in contact with the gas mixture at a temperature of -40.degree. C. to 90.degree. C. under normal pressure.
