Abstract
This invention describes a method for co-producing isobutene and methyl tert-butyl ether in a catalytic distillation column, wherein contacting with solid acid catalysts the charged tert-butanol mixture undergoes dehydration and etherification. The mixture of isobutene and methyl tert-butyl ether withdrawn from the column top can be further separated, thus high purity isobutene and fuel-additive methyl tert-butyl ether are obtained.
