Description

Technical Field

[0001] This utility model relates to the field of etherification reactor technology, and in particular to an etherification reactor for MTBE. Background Technology

[0002] MTBE (methyl tert-butyl ether) is a commonly used gasoline additive, primarily used to increase gasoline octane rating, improve combustion efficiency, and reduce harmful emissions from exhaust gases. Its production process involves an etherification reaction, specifically using isobutylene and methanol as raw materials. The etherification reaction occurs under the action of an acidic catalyst (such as an ion exchange resin) to produce MTBE. Therefore, the etherification reaction is the core process step in MTBE production. In MTBE production, an etherification reactor is required for the reaction. However, during the production process, the catalyst is prone to precipitation, which can easily affect the reaction rate with the raw materials. In the prior art, such as the authorization announcement number CN 221558392 U, an "etherification reactor for synthesizing MTBE" is disclosed, which specifically discloses that a first motor drives a first rotating shaft and a first stirring rod to rotate, which can easily avoid catalyst precipitation and facilitate mixing, thereby improving reaction efficiency. The mixing component can further improve the reaction rate. However, in the above technology, the reaction rate is improved by simply stirring. The space for stirring in the tank is limited, and precipitation still occurs. Therefore, this utility model proposes an etherification reactor for MTBE to solve the problems existing in the prior art. Utility Model Content
