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.
