Removal of sulfur compounds from hydrocarbon feedstreams using cobalt containing adsorbents in t |
June 17, 2003 |
| A process for removing sulfur compounds from hydrocarbon feedstreams, particularly those boiling in the naphtha range, by contacting the feedstream with an adsorbent comprised of cobalt and one or more Group VI metals selected from molybdenum and tungsten on a refractory support. This |

Benzene removal and conversion from gasoline boiling range streams |
March 15, 1994 |
| A totally contained adsorption process for the substantial total removal and conversion of benzene to cyclohexane in gasoline boiling range streams. At least a portion of the gasoline boiling range stream is passed through an adsorption zone containing an adsorbent which will selectively |

Benzene removal from a heartcut fraction of gasoline boiling range streams |
March 30, 1993 |
| A method for selectively separating benzene from gasoline boiling range streams by first fractionating the stream to produce a C.sub.6 heartcut fraction which is then passed to an adsorption zone comprised of a bed of solid adsorbent material capable of selectively removing benzene from |

Benzene removal from gasoline boiling range streams |
February 16, 1993 |
| A method for selectively separating benzene from gasoline boiling range streams by first passing the stream to an adsorption zone comprised of an adsorbent capable of selectively adsorbing benzene from the stream. A substantially benzene-free stream results and the adsorbent is regenerat |
