Title:
METHYL CHLORIDE PRODUCING METHOD WITH IMPROVED ENERGY EFFICIENCY USING MULTI-STEP REACTION
Document Type and Number:
WIPO Patent Application WO/2024/063425
Kind Code:
A1
Abstract:
The present invention relates to a methyl chloride producing method with improved energy efficiency using a multi-step reaction, wherein in the production of methyl chloride through methane chlorination, chlorinated methane such as methyl chloride is separated from products of a methane chlorination reaction as a primary reaction, and the remaining mixture of unreacted methane and hydrogen chloride is contacted with methanol without separation of the hydrogen chloride, or the product mixture after the reaction is directly added and reacted with methanol, thereby achieving a conversion into methyl chloride, whereby an improvement in the process energy efficiency can be attained.
