    摘要: A method for the oxidative conversion of feed organic compounds, such as methane and ethane, to product organic compounds, such as ethylene, in the presence of a free oxygen containing gas and a contact material comprising: (1) Group IA and/or Group IIA metals/O.sub.2 /halogen; (2) Group IA metals/La Series metals/O.sub.2 /halogen and, optionally, Group IIA metals; (3) Group IA metals/Zn/O.sub.2 /halogen and, optionally, Group IIA metals; (4) Group IA metals/Ti or Zr/O.sub.2 /halogen and, optionally, Group IIA metals; (5) Group IA and/or IIA metals/phosphate/halogen or (6) Co/Zr, Zn, Nb, In, Pb and/or Bi/P/O.sub.2 halogen, and, optionally, Group IA metals and/or S, in which a contact material containing no halogen or an ineffective amount are activated and/or regenerated by contacting them with a halogen and, when the contact material is contact material (6), with a reducing agent or both a reducing agent and a halogen. A method of making the contact materials is also disclosed in which they are prepared without a halogen and calcined in air and the halogen is supplied by, thereafter, treating them with a halogen and, when the contact material is contact material (6), treating it with a reducing agent to reduce its state of oxidation, prior to use, preferably in the reaction zone in which it is to be used.

    摘要: A process for absorption and subsequent desorption of carbon dioxide comprises contacting a CO.sub.2 -containing gas with a solid sorbent comprising alkali metal oxide and/or hydroxide (preferably LiOH) and lanthanum oxide. The used solid sorbent can be regenerated by heating, so as to desorb absorbed carbon dioxide.

    摘要: Methane is converted to higher hydrocarbons, paticularly ethylene and ethane, and most desirably ethylene, by:contacting a feed comprising methane, such as natural gas, and a free oxygen containing gas, such as oxygen or air, with a solid contact material, comprising:(a) a component comprising: at least one metal selected from the group consisting of Group IA and Group IIA metals;(b) a component comprising: at least one material selected from the group consisting of phosphate radicals and compounds containing phosphate radicals; and(c), optionally, at least one material selected from the group consisting of halogen ions and compounds containing halogen ions,under oxidative conversion conditions sufficient to convert the methane to the higher hydrocarbons.
