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&#x2014;Pt supported nanocrystalline ZrO. The process provides methane conversion of 54-99% with H/CO ratio of 1.14 to 1.42 (mol %) in the temperature range of 250 to 750 800&#xb0; C. at atmospheric pressure.

Ni&#x2014;Pt&#x2014;ZrO2 nanocrystalline oxide catalyst and process thereof useful for the production of syngas by combining oxy-dry reforming of natural gas

The present invention provides a process and catalyst system for the production of synthesis gas (a mixture of CO and H) from greenhouse gases like methane and carbon di oxide. The process provide a single step selective reforming of methane with carbon dioxide to produce synthesis gas over Ce&#x2014;Ni&#x2014;MgAlOcatalyst prepared by using combination of two methods evaporation induced self-assembly and organic matrix combustion method. These suitably combined methods generate a unique catalyst system with very fine Ni nano clusters evenly dispersed in high surface area support. The process provides both Methane and carbon di oxide conversion more than 90% without any noticeable deactivation till 100 hours between temperature range of 500-800&#xb0; C. at atmospheric pressure.

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&#xb0; C. The process provides methanol conversion of 45-100% with a selectivity of the DME up to 100%.
