ABSTRACT:
Disclosed is an integrated process for the generation of a mixture of ethers, such as diisopropyl ether, methyl tertiary butyl ether, and/or isopropyl tertiary butyl ether, from a crude by-product acetone stream composed of acetone, tertiary butyl alcohol and methanol by passing such a stream, in the presence of hydrogen, over a catalyst system characterized by having both a hydrogenation activity gradient along the reactor in one direction and an etherification activity gradient in the opposite direction.
