Patents by Inventor Mariya N. Timofeeva

Mariya N. Timofeeva has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10668455
    Abstract: A catalyst and a process for using the catalyst are presented. The catalyst is a heterogeneous catalyst and includes active metal halides bonded to functional groups. The functional groups are bonded to a polymeric backbone to form the structure supporting the catalyst. The catalyst is useful for the dimerization of acetylene to convert the acetylene to a larger hydrocarbon, and in particular to dimerize acetylene to vinylacetylene.
    Type: Grant
    Filed: December 14, 2018
    Date of Patent: June 2, 2020
    Inventors: Timur V. Voskoboynikov, Alakananda Bhattacharyya, Nikolay Y. Adonin, Mariya N. Timofeeva, Sergey A. Prikhodko, Valentin N. Parmon

  • Patent number: 9328037
    Abstract: A process for making linear alkyl aromatics is described. The process involves preparing the paraffin feed by dehydrogenating normal paraffins, selectively hydrogenating any diolefins, and adsorbing any aromatics to form an olefin feed. The olefin feed is contacted with an aromatic feed in the presence of an ionic liquid catalyst to form a mixture of alkylated aromatics. The ionic liquid catalyst is separated from the mixture of alkylated aromatics by gravity, and any ionic liquid retained in the alkylated aromatics is removed by adsorption or extraction. The mixture of alkylated aromatics is then separated into monoalkylated aromatics and dialkylated aromatics.
