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.

Petrol, Diesel Subsidies Three Times Higher than E-Vehicle Budget: Study

The cuts to fuel excise and oil company margins announced late last year resulted in a major drop in government revenue

Despite the commitment to reduce air pollution and achieve at least 30 per cent of new vehicle sales being electric by 2030, the Indian government subsidised conventional transport by Rs 26,957 crore over the last nine months, far outpacing the Rs 10,000 crore spending over three years. Pixabay

India’s subsidies to petrol and diesel between October 2018 and June 2019 amounted to almost three times the three-year government budget for electric vehicle (EV) support, a new study revealed on Thursday.

The study by Global Subsidies Initiative (GSI) of the International Institute for Sustainable Development (IISD) said the government could redirect the money collected in tax via petrol and diesel towards EVs and see far more growth.

Despite the commitment to reduce air pollution and achieve at least 30 per cent of new vehicle sales being electric by 2030, the Indian government subsidised conventional transport by Rs 26,957 crore over the last nine months, far outpacing the Rs 10,000 crore spending over three years on its flagship EV program and faster adoption and manufacturing of electric vehicles.

“The cuts to fuel excise and oil company margins announced late last year resulted in a major drop in government revenue. The money would have been better spent in supporting India’s ambitious agenda to adopt EVs and renewable energy rather than perpetuating dependence on petrol and diesel,” IISD Associate Tara Laan said in a statement.

India is heavily reliant on fossil fuels in the transport sector, which contributes to greenhouse gas emissions and alarming levels of air pollution.

Transitioning to EVs could reduce the level of toxic air pollutants relative to conventional vehicles and shift the source of these emissions away from cities.

“With the decision to reinstate the fuel excise and further lower GST on EVs, the government is back on the right track,” said Purva Jain, GSI India Program Consultant and co-author of the report.

“It should also allocate some of the fuel excise and road and infrastructure cess to boost support to EVs,” said Jain.

This would help in reducing dependence on imported crude oil and improve air quality.

“Price cuts for petrol and diesel have the opposite effect, sending motorists a price signal to continue using fuel and, more importantly, a message that the government intends to intervene when international oil prices escalate.”

A main recommendation of the study is to reallocate subsidies for oil and fuel to programs that support India’s clean energy transition, including implementing additional policies that would support the EV market.

“We recommend that government implements pricing policies that promote EV charging during times when renewable electricity is being generated,” said Laan.
