Abstract: An integrated process for producing ethers, such as methyl tertiary butyl ether, is disclosed. Specific undesired compounds such as water, methanol or the product ether are removed from a hydrocarbon recycle stream withdrawn from the etherification zone by contacting the recycle stream with a solid regenerable sorbent. Preferably, the sorbent does not remove mono- or diolefinic hydrocarbons from the recycle stream. The treated recycle stream is preferably fractionated to yield isobutane passed into a dehydrogenation zone and normal butane which is charged to a butane isomerization zone.

Abstract: A method is disclosed for regenerating a solid adsorbent which has been used to remove oxygen-containing hydrocarbonaceous compounds, water or sulfur-containing compounds from a hydrocarbon stream. The method is preferably applied to molecular sieves which have been used to remove ethers, alcohols and/or water from a light liquid phase hydrocarbon stream such as a stream which is rich in C.sub.4 hydrocarbons. The regeneration method includes stripping the adsorbent with a low temperature hydrogen-rich gas stream, which preferably has a temperature below about 200.degree. F., and then gradually increasing the temperature of the gas stream to customary regeneration temperatures.
