Quadrise: Tests demonstrate bioMSAR a ‘viable’ diesel engine fuel

Quadrise Fuels International (Quadrise) says that initial testing of its bioMSAR emulsion fuel have confirmed its viability as a diesel engine fuel.

According to Quadrise, results showed that its sustainable fuel product achieved higher efficiency and 20-25% lower NOx compared to baseline testing on diesel at the prevailing test conditions on a high-speed engine.

The company also said the results indicated ‘further optimisation should be possible’ in terms of operating conditions.

As previously reported, Quadrise launched bioMSAR – a ‘synthetic alternative to HFO’ – in December 2020. The fuel utilises the company’s MSAR technology to combine renewable glycerol with water and refinery residues to produce an oil-in-water emulsified synthetic HFO.

Initial testing of bioMSAR was carried out at Aquafuel Research Ltd’s UK test facility. According to Quadrise, results showed that particulates were ‘comparable for both fuels’, and the pre-atomisation of the hydrocarbon in bioMSAR ‘appears to be enabling good carbon burn out and the avoidance of black soot even though the test engine is designed for diesel and light fuels as opposed to residue-based fuels’.

The company said that future third-party testing to build upon the ‘positive initial results’ will incorporate optimisation at various loads, with further quantification of efficiency and emissions.

‘We are pleased to have achieved such positive results for bioMSAR in terms of efficiency and emissions, especially as the test engine is designed for diesel as opposed to residue-based fuels,’ said Mark Whittle, COO of Quadrise.

‘These results give us a solid foundation for the future testing that is planned for medium (4-stroke) and low speed (2-stroke) engines, which are more typically used by our clients.’

Paul Day, CEO & Founder of Aquafuel, added: ‘This initial testing demonstrates bioMSAR is a viable candidate for fossil fuel replacement in larger engines and results indicate a significant NOx reduction, of the order of 20-25%, and no loss of efficiency compared to diesel.’
