Processes and systems for Cmonoolefin conversion. In some examples, the process can include reacting a first mixture that includes Cmonoolefins and a first oxygenate to produce a first effluent that includes a first ether and <1 wt. % of any first di-Colefin. A first product that includes the first ether and a first byproduct that includes at least a portion of any first di-Colefin and unreacted Cmonoolefins 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-Colefin. The reaction of the second mixture can produce a greater amount, on a mole basis, of the second di-Colefin than the second ether.

Processes and systems for C3+ monoolefin conversion

The invention relates to methods and equipment for converting Colefin to, e.g., one or more of di-Colefin, oligomers and polymers of Colefin, branched C-aldehydes, C-carboxylic acids, and Coxygenates. The invention encompasses producing methyl tert-butyl ether and diisobutylene, and converting methyl tert-butyl ether to isobutylene.
