  • Nano Ni—Zr oxide catalyst for activation of methane by tri-reforming and a process for the preparation thereof
    Patent number: 10351424
    Abstract: The present invention provides a Ni—Zr oxide catalyst and a process for the preparation of the catalyst. The invention further provides use of the catalyst for the production of synthesis gas (a mixture of CO and H2) by Tri-reforming of methane. The process provides a direct single step selective vapor phase partial oxidation of methane to synthesis gas over Ni—ZrO2 catalyst between temperature range of 600° C. to 800° C. at atmospheric pressure. The process provides a methane conversion of 1-99% with H2 to CO mole ratio of 1.6 to 2.2.
    Type: Grant
    Filed: March 30, 2016
    Date of Patent: July 16, 2019

  • Ni—Pt—ZrO2 nanocrystalline oxide catalyst and process thereof useful for the production of syngas by combining oxy-dry reforming of natural gas
    Patent number: 9889434
    Abstract: The present invention provides a process and catalyst for the autothermal and dry reforming of methane to produce syngas. The process provides a direct single step gas phase reforming of methane or natural gas to syngas over Ni—Pt supported nanocrystalline ZrO2. The process provides methane conversion of 54-99% with H2/CO ratio of 1.14 to 1.42 (mol %) in the temperature range of 250 to 750 800° C. at atmospheric pressure.

  • Process for the preparation of phosphorous containing mesoporous alumina catalyst for selective dehydration of methanol to dimethyl ether
    Patent number: 9468914
    Abstract: The present invention provides an improved process for the preparation of phosphorous containing mesoporous alumina catalyst for selective dehydration of methanol to dimethyl ether. The process provides a single step selective vapor phase dehydration of methanol to produce dimethyl ether over phosphorous containing mesoporous alumina (P/Al2O3) catalyst at a temperature in the range of 150-350° C. The process provides methanol conversion of 45-100% with a selectivity of the DME up to 100%.
