Production of cleaner diesel by a new method

London: A team of researchers from two European universities have discovered a new approach to the production of much cleaner diesel.

Researchers from the Belgium’s University of KU Leuven and Netherland’s Utrecht University used catalysts to produce clean diesel, which can quickly be scaled up for industrial use, according to a KU Leuven statement.

Catalysts are substances that trigger the chemical reactions that convert raw material into fuel. In the case of diesel, small catalyst granules are added to the raw material to sufficiently change the molecules of the raw material to produce useable fuel.

The catalyst used for this particular study has two functions, represented by two different material — a metal (platinum) and a solid-state acid.

During the production process for diesel, the molecules bounce to and fro between the metal and the acid. Each time a molecule comes into contact with one of the materials, it changes a little bit. At the end of the process, the molecules are ready to be used for diesel fuel.

The assumption has always been that the metal and the solid-state acid in the catalyst should be as close together as possible to speed up the production process by helping the molecules bounce to and fro more quickly.

However, Johan Martens of KU Leuven and Krijn de Jong of Utrecht University have now discovered that this assumption is incorrect.

“Our results are the exact opposite of what we had expected. At first, we thought that the samples were switched or that something was wrong with our analysis”, said professor Martens.

“We repeated the experiments three times, only to arrive at the same conclusion — the current theory is wrong. There has to be a minimum distance between the functions within a catalyst. This goes against what the industry has been doing for the past 50 years.”

Cars that are driven by this clean diesel would emit far fewer particulates and carbon dioxide. The researchers believe that their method can be scaled up for industrial use with relative ease, so the new diesel could be used in cars in 5-10 years.

The new technique can be applied to petroleum-based fuels but also to renewable carbon from biomass.

B R Ambedkar

Brussels: Belgium’s most prestigious and oldest university, KU Leuven (KUL) marked India’s Constitution Day as an honour to BR Ambedkar with a big audience of international relations and law students on federalism in India.

The event took place on Friday in Aula Pieter de Somer, the largest lecture hall of the university and was attended by more than 300 students and faculty of KUL.

Professor Idesbald Goddeeris, who runs the India programme at KU Leuven, organised the event.

A panel discussion compared the Indian Constitution with the Belgian Constitution.

M.S Vishnu Sankar, a practising lawyer in the Supreme Court of India, spoke on the concept of federalism as enshrined in the Constitution of India.

Indian Ambassador Manjeev Singh Puri delivered the opening address while a visiting Indian professor, Rajendra Jain, provided a European Union (EU) perspective.

The Constitution of India was adopted on November 26, 1949, before it came into force on January 26, 1950.

BR Ambedkar was the main architect of the Indian constitution.

New Delhi: With Indian Oil Corporation hiking the price of petrol and diesel by 36 paise/litre and 87 paise/litre (including State levies), respectively, from midnight of November 15/16, petrol in the capital will now cost Rs 61.06/litre and diesel will come at Rs 46.80/litre.

Indian Oil said at a Press release that  current international prices of petrol and diesel and the rupee-dollar exchange rate has compelled the hike in prices.

The public sector oil marketing company said it would continue to closely monitor the movement of prices in the international oil market as well as the rupee-dollar exchange rate.

The developing trends would be reflected in future price changes, it added.

New Delhi: Indian Oil Corp (IOC) announced that diesel price has been slashed by 50 paisa per litre in Delhi, including state levies, with corresponding price changes in other states, effective from Thursday.

“The current level of international prices and INR-USD exchange rate warrant a price increase, which is being passed on to consumers with this price revision,” state-run IOC said in a statement.

With this, the retail price per litre of diesel from October 1 will be Rs.44.95 in Delhi, Rs.48.71 in Kolkata, Rs.52.08 in Mumbai and Rs.46.08 in Chennai.

On September 1, petrol price was cut by Rs.2 per litre and diesel by Rs.0.50 a litre.

On Wednesday, the Maharashtra government decided to levy a surcharge of Rs. 2 on petrol and diesel, effective from October 1.
