Abstract: Systems and methods for producing MTBE and 1-butene are disclosed. A crude C4 hydrocarbon stream is obtained by removing butadiene from a C4 hydrocarbon mixture of a hydrocarbon cracking unit. The crude C4 hydrocarbon stream is then distilled to form (a) a first distillate stream comprising isobutylene, isobutane, 1-butene, or combinations thereof and (b) a first bottom stream comprising 2-butene, n-butane, a deactivating compound for catalyst of MTBE synthesis. The first distillate stream is then flowed to a MTBE synthesis unit to produce via reaction with methanol. The raffinate from the MTBE synthesis unit comprising isobutane and 1-butene is further separated in a distillation column to produce 1-butene.
