<p>A process in which a dilute isobutylene stream containing normal butenes is hydroisomerized to remove butadiene and to isomerize the butene-1 to butene-2 and concurrently separate the higher boiling butene-2 from the remainder of the C4 stream in a distillation column reactor. The overheads containing a concentrated isobutene feed from the distillation column reactor are fed along with methanol to an etherification reactor where the isobutylene reacts with the methanol to form MTBE. The butene-2 bottoms may be skeletally isomerized to isobutene and utilized in an etherification reactor.</p> |
