Isomerization of n-Butenes in MTBE Manufacture
Published: January 1980
This study covers a process in which the n-butenes in the spent C4 fraction from an MTBE unit are isomerized to isobutylene and recycled to increase MTBE production. The literature indicates that the process for skeletal isomerization of n-butenes has been studied extensively in the laboratory but not fully developed at the time of writing.
