Technology for Methyl-Ethyl-Ketone Production (MEK)

1. This process solves technical problems about the preparation of efficient cationic resin catalyst and upsizing of the reactor of n-butene hydration, formed the innovative technology with independent intellectual property rights on catalyst, technology and engineering. Main technical features are as follows:
2. The efficient cationic temperature resistance resin catalyst has a concentrating distribution of aperture and does not contain free and unstable sulfonic groups.
3. The single pass conversion of n-butene is high (8%), the selectivity of SBA can reach up to 97%.
4. The circulating water double-column desulfonation process is totally new. It effectively removes the sulfonic acid group and metal cations in the circulating water. The operation period of catalyst is therefore lengthened to 12,000h.
5. The alkaline compounds are used to reduce acidity of dehydrogenation catalyst. The catalyst enjoys high activity (the conversion of SBA reaches 83%) and good selectivity (the selectivity of MEK reached up to 98%).
6. The large-scale hydration reactor provides support for large-scale MEK unit construction.
7. The economy efficiency is high. The consumption of n-butene is low and the comprehensive energy consumption is decreased.
