Methanol conversion to carbon monoxide technology:

brief introduction

The product of our company, the device for preparing carbon monoxide, is used to prepare carbon monoxide by methanol cracking pressure swing adsorption. This technology uses methanol as raw material, which is cracked into a mixture of hydrogen and carbon monoxide by catalyst under a certain temperature and pressure, and then obtains pure hydrogen and carbon monoxide through pressure swing adsorption separation.

Technical features:

·Easy source of raw materials, convenient transportation and storage, and stable price.

·The device is corrosion free, highly automatic, simple and easy to operate.

·Low energy consumption and low product cost.

·The unique catalyst has few side reactions, high conversion and is not easy to form carbon.

Reaction principle:

CH3OH→CO+2H2+Q

Performance characteristics

Mature technology, reliable operation.

Easy source of raw materials, convenient transportation and storage, and small price fluctuation.

Simple process, small land occupation, low investment and short payback period.

The device is highly automatic and easy to operate.

There are many product specifications, which are suitable for medium and small scale CO production.

Brief description of process flow

Methanol (containing a small amount of desalted water) enters the reactor through pressurization, vaporization and overheating. Under the action of catalyst, conversion endothermic reaction takes place to obtain a mixture of about 68% (v/v) hydrogen and 30% (v/v) CO. The mixture is purified by pressure swing adsorption (PSA) separation technology to obtain 99.99% (v/v) hydrogen and 99.5% (v/v) CO.

Reaction principle

CH3OH → CO+2H2 －90.7KJ/mol

Main performance indicators

Unit scale (CO): 50~500Nm3/h

Purity (CO): 96%~98.5% (v/v)

Temperature (CO): normal temperature or production of H2 and CO mixture
