Abstract: Reduction of carbon oxides products in oxidative pyrolysis of halogenated methanes in gas phase halogen-catalyzed oxidative-pyrolytic, non-flame, conversion of methane to higher molecular weight hydrocarbons is carried out in the presence of oxygen-containing gas which is primarily introduced in a latter portion of the process sequence reducing the oxygen requirement for effective suppression of formation of carbonaceous deposits thereby reducing carbon oxides product. Conversion of halogenated methanes to high yields of ethylene by conduct of the reaction in the presence of methane further reduces oxygen requirements and results in insignificant solid carbonaceous deposit formation.

Abstract: A plastic cap assembly has a base cap that can be installed on the neck of a container. Within the base cap there is a pour spout that serves as a sealing pin, can be moved axially upwards and downwards, and is closed off at the top. On the base cap there is a screw cap that can be turned. The screw cap has a central opening in which the pour spout that serves as the sealing pin engages when in the closed position. The pour spout has an outside thread that engages with an inside thread beneath the central opening in the screw cap. The advantges of this cap assembly lie in its good sealing characteristics and in the fact that, provided with a suitable penetrator, it can be used on containers sealed with a membrane or a foil.
