Embodiments described herein generally relate to new processes and systems for producing isobutylene. Embodiments of the present disclosure also generally relate to new processes and systems for producing PIB, such as HR-PIB. Integrated processes for producing isobutylene from ethylene and/or crude C4 (CC4) streams, which may then be converted to PIB, are also provided. In an embodiment, a process for producing isobutylene is provided. The process includes dimerizing ethylene to produce a dimerization product effluent comprising a normal butylene. The process further includes skeletal isomerizing at least a portion of the normal butylene present in the dimerization product effluent to form a skeletal isomerization product effluent comprising isobutylene. The process further includes isomerizing at least a portion of 1-butene present in the skeletal isomerization product effluent to form an isomerization product effluent comprising 2-butene. The process further includes separating isobutylene and 2-butene from the isomerization product effluent.
A process for producing isobutylene, the process comprising:
A process for producing isobutylene from ethylene and crude C4 (CC4), comprising:
A process for producing polyisobutylene, the process comprising:
