    Abstract: By the present invention, a process is provided to use a modified clinoptilolite adsorbent suitable for the separation of carbon monoxide from hydrogen and hydrocarbon streams without adsorbing hydrocarbons such as paraffins and olefins. In typical applications in platforming units within refineries, these hydrogen streams contain from 5 to 20 parts per million of carbon monoxide. In other applications the level of carbon monoxide may be higher. The separation of carbon monoxide from the hydrogen stream is achieved by using a clinoptilolite molecular sieve that has been ion-exchanged with at least one cation selected from lithium, sodium, potassium, calcium, barium, and magnesium.

    Abstract: The present invention relates to a process for the separation of ethanol from a mixture thereof with ethyl tert.-alkyl ether employing a selective adsorbent comprising a mixture of sodium zeolite Y in combination with alumina wherein the percentage of the sodium zeolite Y ranges between 10 and 40 wt-%. The invention reduces the cost of this separation which is complicated by an azeotrope formation between the alcohol and the ether.

    Abstract: The present invention is a cyclic process for the preparation of ethyl tert.-alkyl ethers by the reaction of an alcohol, ethanol, with an iso-olefin such as isobutylene or isoamylene wherein an effluent from the reaction zone is separated in a distillation column to provide an overhead effluent stream and a bottoms effluent stream comprising ethyl tert.-alkyl ether and unreacted ethanol. The unreacted ethanol is recovered in an adsorption zone comprising a selective adsorbent selected from the group consisting of zeolite 13X, sodium zeolite Y, alumina, silicalite and mixtures thereof. The invention is useful in recovering unreacted ethanol from the bottoms effluent stream and returning the unreacted ethanol to the reaction zone. The invention reduces the cost of this separation which is complicated by the formation of an azeotrope between the unreacted alcohol and the ether.

    Abstract: A process is disclosed for improving catalyst performance and yields in the manufacture of motor gasoline components. More particularly the process is directed to the removal of H.sub.2 S, sulfur compounds, trace amounts of acetonitrile or acetone or propionitrile from a hydrocarbon feedstock, comprising a C.sub.3 -C.sub.5 product fraction from a fluid catalytic cracking unit which may be used subsequently in an etherification process for the production of ethers such as MTBE and TAME and/or an alkylation process for the production of alkylate. The hydrocarbon feedstock is passed to an amine treating zone, a mercaptan sulfur removal zone and an adsorption zone for the removal of sulfur compounds, water and trace amounts of acetonitrile or acetone or propionitrile. The regeneration of the adsorption zone includes the contacting of the sorbent with a heated regenerant vapor stream. The spent regenerant vapor stream is condensed to provide a hydrocarbon phase and an aqueous phase. The trace amounts of the acetonitrile, acetone, and propionitrile are removed in the aqueous phase. The hydrocarbon phase is treated to remove sulfur compounds and can be recycled as the regenerant.

    Abstract: A process for the regeneration of oxygenate containing adsorbents uses regenerant streams such as LPG and isomerate products for the desorption of oxygenate compounds. The process discloses arrangements for the integration of regenerant treatment into the adsorption scheme and for the enhancement of the isomerate product. The integrated flowscheme can be used to remove sulfur and water from contaminated regenerants or to deliver the oxygenates into the gasoline pool.
