Process for recovering alkenes from cracked hydrocarbon streams |
April 28, 1998 |
| A hydrocarbon stream is cracked to produce a hot gaseous stream which is compressed and cooled to condense almost all of the hydrocarbons contained in the stream. A noncondensed stream remaining after the condensation step, comprised predominantly of hydrogen and C.sub.1 to C.sub.3 h |

Process for the purification of carbon dioxide |
October 7, 1997 |
| Sulfur compounds are removed from gaseous carbon dioxide by contacting the carbon dioxide with water vapor in the presence of a carbonyl sulfide hydrolysis catalyst, thereby converting carbonyl sulfide in the gas stream to hydrogen sulfide, contacting the resulting gas stream with ferric |

Process for the production of ethanol and isopropanol |
January 30, 1996 |
| An ethene stream which contains ethane as an impurity or a propene stream which contains propane as an impurity is hydrated with water vapor in the presence of a hydration catalyst to produce ethanol or isopropanol, respectively. After removal of the alcohol the gaseous product stream is |

Process for the production of alkene polymers |
November 28, 1995 |
| An ethylene stream which contains ethane as an impurity or a propylene stream which contains propane as an impurity is contacted with a polymerization catalyst thereby producing a polymer product containing unreacted ethylene or propylene and the corresponding alkane. A gas mixture c |

Process for the production of hydrocarbon partial oxidation products |
November 14, 1995 |
| An ethylene stream which contains ethane as an impurity or a propylene stream which contains propane as an impurity is subjected to adsorption at a temperature of 50.degree. to 200.degree. C. in a bed of adsorbent which selectively adsorbs ethylene or propylene, thereby adsorbing substan |

Process for the production of oxo products |
October 31, 1995 |
| A propylene stream which contains propane as an impurity is contacted with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst thereby producing a product stream containing butyraldehyde and/or n-butyl alcohol, unreacted propylene and propane. A gas mixture co |

Method of producing unsaturated hydrocarbons and separating the same from saturated hydrocarbons |
November 15, 1994 |
| Method of separating a gaseous alkene from a gaseous alkane by a pressure swing adsorption process unit alone or in combination with the distillation column wherein the alkene is preferentially adsorbed onto a bed of 4A zeolite at a temperature of about 50.degree. to about 200.degree |
