American Refining Group taking 1/3 stake in Amyris/Cosan Novvi JV; accelerating commercialization of renewable base oil and lubricants

July 19, 2016

American Refining Group (ARG) is taking a 33.3% stake in Novvi LLC, a joint venture of Amyris and Brazil-based Cosan S.A. formed in 2011 to produce renewable base oils and lubricants from Amyris’ Biofene—Amyris’s brand of a renewable, long-chain, branched hydrocarbon molecule called farnesene (trans-ß-farnesene). (Earlier post.) Both Amyris and Cosan will continue to hold share ownership stakes in Novvi, together with ARG.

Biofene is the basis for a wide range of products varying from specialty products such as cosmetics, perfumes, detergents and industrial lubricants, to transportation fuels such as diesel and jet fuel.

BASF 2016 science competition seeks synthetic lubricant solutions for future high-efficiency vehicles

March 31, 2016

BASF has kicked off its second annual North American Science Competition. This year’s competition focuses on chemistries that can be used to develop a synthetic fluid to meet the needs of future high-performance, high-efficiency engines and transmissions.

With more advanced machinery, lubricating and functional fluids represent a steadily growing industry projected to reach $11 billion by 2020. Synthetic fluids, which are more expensive than petroleum-derived materials, address increasing market demands for higher quality and purity, increased performance and more stringent environmental standards. By developing high performing synthetic fluids with better thermal stability, BASF aims to extend the life cycle of these materials, reduce waste and support the development of more fuel-efficient vehicles.

Northwestern researchers discover crumpled graphene balls are a promising lubricant additive

January 26, 2016

Researchers at Northwestern University’s McCormick School of Engineering have found that crumpled graphene balls are an extremely promising lubricant additive. In a series of tests, a polyalphaolefin base oil with only 0.01–0.1 wt % of crumpled graphene balls outperformed a fully formulated commercial lubricant in terms of friction and wear reduction. A paper on their work is published in the Proceedings of the National Academy of Sciences.

For the average car, 15% of the fuel consumption is spent overcoming friction in the engine and transmission. While oil helps reduce this friction, researchers have long sought additives that enhance oil’s performance. Ultrafine particles are often used as lubricant additives because they are capable of reducing friction and protecting surfaces from wear. They also tend to be more stable than molecular additives under high thermal and mechanical stresses during rubbing. However, they also can aggregate, reducing the effective concentration.
