Less sulphur in Indian petrol

02.07.2008
For the past five years, scientists from SINTEF and Indian Institute of Petroleum (IIP) in India have attempted to develop cheaper methods to reduce the amount of sulphur in petrol. They have now produced results they are considering patenting.
Restrictions
Sulphur in fuel is harmful to the environment, and restrictions in this area worldwide have become tougher. In a densely populated country like India, sulphur pollution is particularly noticeable through acid rain and smog. At the same time, sulphur poisons the catalyst in vehicles, which can lead to greater emissions of nitrogen oxides.

Head of Project Elisabeth Tangstad at SINTEF Materials and Chemistry says that the project with the Indian scientists started with finding more environmentally-friendly and less energy-demanding methods for removing sulphur from petrol.

Cheaper – and with less energy
Most refineries worldwide reduce the sulphur content in petrol through hydrotreating. This is a relatively expensive process with a high consumption of hydrogen. SINTEF and IIP wanted to develop cheaper and less energy-consuming methods with lower emissions of CO2, and discovered that custom-made porous materials that removed the sulphur compounds from the fuel were a good alternative.

“In this process, the material removes the sulphur without a reaction necessarily occurring,” says Tangstad.

Up scaling
The scientists have now designed, produced and tested a lot of materials on a small scale based on knowledge about the properties of the different material components. The most promising samples have later been up scaled and sent to IIP, which has carried out trials in its own laboratory in more realistic conditions.

In order for the Indian refineries to utilise the new methods, flow charts need to be constructed showing how the innovations can be incorporated into the refinery activities.

Tangstad emphasises that this has been a collaborative project between India and Norway with both institutes benefitting from each other’s background and experiences. In recent years, SINTEF has hosted several Indian scientists on exchanges.

The “Petrol Project” concluded last year. The scientists applied for an extension of a two-year diesel project, which has been granted. The Ministry of Foreign Affairs is financing a contract worth NOK 2.7 million with a possible extension to NOK 5.7 million.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
