Bio–Fuels Indian Oil Develops Technology for Co-Processing Non Edible Oils

Editor: Dominik Stephan

In a major technological breakthrough that can be a game changer for advancing use of bio-diesel in the country and ensuring ready acceptance of the fuel by the automobile industry; Indian Oil has successfully developed and commercialized a technology to co-process non-edible vegetable oil in the existing Diesel Hydrotreating (DHDT) units of a petroleum Refinery to make Bio-diesel.

Faridabad/India – This is first time in India and possibly the first in the world when Jatropha oil has been used for Co-processing in a petroleum refinery. This technology for co-processing of Jatropha oil has been developed by the R&D Centre of Indian Oil located at Faridabad.

During the development of this process technology, Indian Oil has also developed a process for de-metallization and de-gumming of vegetable oils. It may be noted that de-metallation of oils is a pre-requisite for Co-processing since metals are poisonous for the catalyst in the DHDT unit.

Jatropha Oil for Bio–Fuels

A total quantity of 200 tons of Jatropha oil was supplied by CREDA Biofuels Limited (A JV of Indian Oil and Chhattisgarh Renewable Energy Development Authority). This oil was used for de-metallization and de-gumming using IOC - R&D developed process and subsequently co-processed in the Chennai Petroleum Corporation Limited (CPCL) Refinery at Manali.

Successful co-processing was demonstrated in the DHDT Unit of the refinery. Operating with a specific catalyst developed by the R&D Centre of Indian Oil, the DHDT unit used upto 6.5 per cent of Jatropha Oil alongwith refinery stream. During the trial, the diesel cetane number improved by 2 units, sulfur content reduced and the inlet temperature of the reactor could also be reduced by 100C with resultant energy savings.
