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.

Abstract: The invention relates to hydrocarbon pyrolysis, e.g., the steam cracking of feeds comprising hydrocarbon and nitrogen-containing compositions. The invention also relates to equipment, systems, and apparatus useful for such pyrolysis, to the products and by-products of such pyrolysis, and to the further processing of such products and co-products, e.g., by polymerization.

Abstract: The invention relates to methods and equipment for converting C3+ olefin to, e.g., one or more of di-C3+ olefin, oligomers and polymers of C3+ olefin, branched C4+-aldehydes, C4+-carboxylic acids, and C4+ oxygenates. The invention encompasses producing methyl tert-butyl ether and diisobutylene, and converting methyl tert-butyl ether to isobutylene.
