A process for producing a fluidized catalyst for synthesis of methanol, which comprises molding a composition comprising

Process for producing fluidized catalyst for synthesis of methanol

A catalyst composition comprising copper oxide, zinc oxide and zirconium oxide, the content of zirconium oxide being 30 to 70% by weight. This catalyst composition is useful for synthesis of methanol from carbon monoxide and/or carbon dioxide and hydrogen by a gas-liquid-solid phase fluidized bed method or a gas-solid phase fluidized bed method.

Catalyst composition suitable for synthesis of methanol

A catalyst composition comprising copper oxide, zinc oxide and an oxyacid of phosphorus or its salt; and a method for producing methanol by reacting carbon monoxide and/or carbon dioxide with hydrogen in the vapor phase in the presence of a catalyst, wherein the catalyst is the aforesaid catalyst composition which has been activated by reduction with a hydrogen-containing gas.

Catalyst composition suited for synthesis of methanol

A process for preparing a catalyst composition comprising copper oxide, zinc oxide and aluminum oxide as essential ingredients and optionally containing boron oxide, which comprises

Preparation of improved catalyst composition

A process for producing methyl formate which comprises dehydrogenating methanol in the vapor phase in the presence of a catalyst containing copper and a cement is disclosed.

Process for producing methyl formate

A process for producing methyl formate which comprises dehydrogenating methanol in vapor phase in the presence as a catalyst of copper, zirconium and zinc and optionally aluminum is disclosed.

A process for the preparation of formaldehyde by subjecting methanol to dehydrogenation in the presence of a catalyst consisting of copper, zinc and selenium as metallic components.

Process for the preparation for formaldehyde

Methanol is dehydrogenated at 500-750.degree. C. using a catalyst whose active components are copper, zinc and sulfur to form a stable product containing 30 to 85% by weight of formaldehyde, 0 to 2% by weight of water, the balance being methanol.
