  • Process for selective production of light olefins and aromatic from cracked light naphtha
    Patent number: 11274257
    Abstract: The present invention provides a process for a production of light olefins and aromatics from cracked light naphtha by selective cracking. The present invention thus provides a process for up grading cracked olefinic naphtha to high value petrochemical feed stocks. This process is based on catalytic cracking in which the catalyst activity is optimized by depositing coke for production of light olefins and aromatics. The proposed process has high flexibility and can be operated either in maximizing olefins as reflected from the PIE ratio or in maximizing aromatics (BTX) at different modes of operation depending upon the product requirement.

  • Process for the preparation of bio-diesel
    Publication number: 20050108927
    Abstract: A process is disclosed for the preparation of biodiesel, whereby oil is subjected to catalytical transesterification, settling, separation, bubble washing and micro filtration at controlled conditions of temperature and turbulence. The process enables production of high quality fuel, termed as biodisel, within a period of as low as 50 hrs. The fuel can be used without blending with any conventional fuel.
