  • Process for the production of ?-valerolactone
    Patent number: 10005747
    Abstract: The present invention provides a process for the hydrogenation of the levulinic acid to ?-valerolactone in a single step with a single Pt supported on hydrotalcite catalyst. The process provides conversion of ?-valerolactone over Pt supported hydrotalcite catalyst at room temperature (25° C.). The process provides a levulinic acid conversion of 34-100% with 20-50 bar hydrogen pressure to give ?-valerolactone selectivity up to 99%.
    Type: Grant
    Filed: July 11, 2016
    Date of Patent: June 26, 2018
    Assignee: Council of Scientific and Industrial Research
    Inventors: Bal Rajaram, Pendem Chandrashekar, Bordoloi Ankur, Konathala Laxmi Narayan Sivakumar, Manoj Kumar, Saran Sandeep

  • Nano Ni—CeO2 catalyst for syngas production and its preparation thereof
    Patent number: 9480974
    Abstract: The present invention relates to Nano Ni—CeO2 catalyst and its preparation thereof useful for syngas production. Particularly, the present invention relates to a process for the activation of methane at low temperature for the production of synthesis gas (mixture of CO and H2) using nanosize Ni—Ce oxide catalyst. More particularly, the present invention relates to a process for the partial oxidation of methane to synthesis gas between temperature range of 450° C. to 800° C. at atmospheric pressure over Ni—CeO2 solid catalyst. The process provides a methane conversion of 20-98% with H2 to CO molar ratio of 1.6 to 2 without deactivation till 100 h.
