METHOD OF PRODUCING ALKANOLAMINES AND APPARATUS FOR PRODUCING SAME.

摘要

IN PRODUCING ALKANOLAMINES BY USE OF A MICROPOROUS MATERIAL AS A CATALYST, THE DIFFICULTY IN INDUSTRIALLY PERFORMING THE PRODUCTION BECAUSE OF THE SHORT LIFETIME OF THE CATALYST IS RESOLVED. A PROCESS OF REGENERATING THE CATALYST BY REMOVING AN ORGANIC SUBSTANCE DEPOSITED ON THE CATALYST BY MEANS OF DECOMPOSING AND/OR EXTRACTING THE SUBSTANCE IS INTRODUCED, AND THEREBY STEADY PRODUCTION IS CARRIED OUT SUBSTANTIALLY OVER THE LONG TERM BY SWITCHING THE REACTION AND THE REGENERATING PROCESSES.
