Problems solved by technology

In order to prevent the reduction of activity, water and carbon dioxide in the raw gas must be removed to the ppb level, so if this pretreatment will increase the cost, it is not realistic

Embodiment 1

[0071] Using an autoclave with an inner volume of 50ml, add 2.5mmol of potassium formate to 10ml of ethanol as a solvent, with Cu(NO 3 ) 2 ·3H 2 O, Mg(NO 3 ) 2 ·6H 2 Cu / MgO was prepared by co-precipitation method while maintaining the pH at 10.0 as a raw material x , add 1g by the Cu / MgO x Gradually impregnated loaded with Na 2 CO 3 (18.7% by mass), Cu / MgO formed by Pd (0.25% by mass) x / Na 2 CO 3 (18.7% by mass) / Pd (0.25% by mass) catalyst, filled with 5MPa synthesis gas (CO: 32.40% by volume, H 2 : 64.58% by volume, Ar: 3.02% by volume), reacted at 160° C. for 5 hours, and the reaction product was analyzed by gas chromatography. The yield of methanol was 75.2 mmol and the yield of ethyl formate was 2.1 mmol. and Pd-unloaded Cu / MgO described in Comparative Example 1 described later x / Na 2 CO 3 (18.7% by mass), exhibited very high activity.

Embodiment 2

[0073] The reaction was carried out by the method described in Example 1 except that the reaction temperature was 180°C. The yield of methanol was 56.4 mmol and that of ethyl formate was 1.1 mmol.

Embodiment 3

[0075] The reaction was carried out by the method described in Example 1 except that the reaction temperature was 140°C. The yield of methanol was 20.7 mmol and that of ethyl formate was 2.2 mmol.

Abstract

This catalyst for methanol synthesis, where methanol is synthesized via a formic ester, is a catalyst for methanol synthesis which carries out a reaction under the presence of a starting material gas containing hydrogen and at least either one of carbon monoxide and carbon dioxide, and an alcohol as a solvent, and includes a catalyst containing Cu, Mg, Na, Pd, and an alkali metal formate salt.

Description

technical field [0001] The present invention relates to a catalyst for synthesizing methanol, a method for producing the catalyst, and a method for producing methanol. More specifically, it relates to a catalyst having high activity when producing methanol from carbon sources such as carbon monoxide and carbon dioxide, and hydrogen, and a method for efficiently producing products using the catalyst. [0002] This application claims the priority of Japanese Patent Application No. 2006-41618 filed on February 17, 2006 and Japanese Patent Application No. 2007-22125 filed on January 31, 2007, the contents of which are cited in this application. Background technique [0003] Usually, when industrially synthesizing methanol, carbon monoxide and hydrogen (synthesis gas) obtained by steam shifting natural gas with methane as the main component are used as raw materials, and catalysts such as copper-zinc are used. Methanol is synthesized under harsh conditions of ~300°C and 5~25MPa ...
