Catalytic distillation device for preparing methanol, and use method thereof

Abstract

The invention discloses a catalytic distillation device for preparing methanol, and a use method thereof. A storage mechanism comprises a supporting plate and a vertical plate, a vertical rod is fixedly connected to the top of the supporting plate, a column is fixedly connected to one side of the vertical plate, a containing groove is formed in the top of the column, and a first through hole part is formed in the outer surface of the column. The invention relates to the technical field of methanol preparation. According to the catalytic distillation device for preparing methanol, and the use method thereof, under the cooperative use of the supporting plate, the vertical plate, the vertical rod, the column , the containing groove, the first through hole part, a second through hole part, a first connecting plate and a limiting hole, a catalyst is intensively placed in the containing groove, and when a sealing cover is opened, the catalyst can be taken out and replaced only by taking out the vertical plate, so the device is convenient to use, and solves the problem that when the catalyst is used in an existing catalytic distillation device, the catalyst is generally and directly placed in the catalytic distillation device, so that the subsequent catalyst is very inconvenient to take out and replace.

Description

technical field [0001] The invention relates to the technical field of methanol preparation, in particular to a catalytic distillation device for preparing methanol and a use method thereof. Background technique [0002] Methanol is the simplest saturated monohydric alcohol with CAS numbers 67-56-1 and 170082-17-4, a molecular weight of 32.04, and a boiling point of 64.7°C. Also known as "wood alcohol" or "wood essence". It is a colorless, volatile liquid with alcohol odor. The lowest dose of human oral poisoning is about 100mg / kg body weight, and oral intake of 0.3-1g / kg can be fatal. Used in the manufacture of formaldehyde and pesticides, etc., and used as an extractant for organic matter and a denaturant for alcohol. Usually produced by the reaction of carbon monoxide and hydrogen. Methanol is flammable and its vapor can form explosive mixtures with air. In case of fire, high heat can cause combustion and explosion. Contact with oxidizing agents may react or cause f...
