Abstract

Processes and systems for C3+ monoolefin conversion. In some examples, the process can include reacting a first mixture that includes C3+ monoolefins and a first oxygenate to produce a first effluent that includes a first ether and < 1 wt. % of any first di-C3+olefin. A first product that includes the first ether and a first byproduct that includes at least a portion of any first di-C3+ olefin and unreacted C3+ monoolefins can be separated from the first effluent. A second olefin mixture, at least a portion of the first byproduct, and a second oxygenate can be combined to produce a second mixture. The second mixture can be reacted to produce a second effluent that includes a second ether and a second di-C3+ olefin. The reaction of the second mixture can produce a greater amount, on a mole basis, of the second di-C3+ olefin than the second ether.

Description

[0001] priority [0002] This application claims priority to US Provisional Application No. interests and 62 / 860,580 and European Patent Application No. 31 October 2019 19206401.2 filed in June 12, 2019 submitted the disclosures of which are incorporated herein by reference in its entirety . Technical field [0003] For C relates generally to embodiments disclosed herein 3+ Method and system for conversion of monoolefins. More particularly, these embodiments relate to one or more C 3+ Monoolefins into two -C 3+ Olefins, C 3+ Olefin oligomers, C 3+ Olefin polymers, C 4+ Aldehyde, C 4+ Carboxylic acids and / or C 4+ Oxygenates (oxygenate) methods and systems. Background technique [0004] C 3+ Monoolefins, e.g. C 4+ Iso-olefins, can be used to produce a number of useful products, such as di -C 4+ Olefins and C 5+ Oxygenates. In one example, isobutene can be used for the preparation of diisobutene is used as a fuel blending component. In another example, isobutene can be used for p...
