20090259063 | SYSTEM AND PROCESS FOR CONTINUOUS INDUSTRIAL PREPARATION OF FLUOROALKYLCHLOROSILANE - The present invention relates to a system, to a reactor and to a process for continuous industrial performance of a reaction wherein an α,β-unsaturated fluorine-substituted olefin A is reacted with an HSi compound B in the presence of a catalyst C and optionally of further assistants, and the system is based at least on the combination of reactants ( | 10-15-2009 |
20120318661 | Method for Modification of a Methane-Containing Gas Stream - A method for modification of a methane-containing gas stream, comprising the steps of: i) withdrawal of at least one substream from a methane-containing gas stream; ii) treatment of the substream with an electrically generated plasma, generating a modified gas composition which comprises a lower fraction of methane than the methane-containing gas stream used and iii) return of modified gas composition into the methane-containing gas stream. This method makes possible the storage of excess power in a natural gas line grid. | 12-20-2012 |
