Study: air pollution caused 1.1M deaths across Africa in 2019, toll from outdoor pollution rising

Green Car Congress

million people worldwide in 2017, the paper notes. The team studied trends in air pollution in Africa to determine impacts on human health and economic development in 54 African countries. In addition to the toll on human health, air pollution imposes economic costs, the study found. billion IQ points across the continent.

KAUST team seeks improved catalysts for Lebedev ethanol-to-butadiene process for renewable rubber

Green Car Congress

Butadiene can also be produced from ethanol by one of two primary methods: Lebedev, which converts ethanol over one catalyst in one reactor, and Ostromisslensky, which converts a mixture of ethanol and acetaldehyde in a two-reactor system. A 2017 analysis by a Ukrainian/French team (Kyriienko et al. Kyriienko, Olga V.

Dynamically tuning the structure of platinum in catalytic converters to enhance performance under different conditions

Green Car Congress

Researchers from France and Germany are proposing a new concept for the dynamic tuning of the structure of platinum nanoparticles on catalytic converters to enhance their performance—especially after cold starts and in urban traffic—and to reduce the consumption of expensive noble metal.

ORNL-led team uses carbon material derived from tire waste to convert used cooking oil to biofuel

Green Car Congress

Using a novel, reusable carbon material derived from old rubber tires, an Oak Ridge National Laboratory (ORNL)-led research team has developed a simple method to convert used cooking oil into biofuel. —Hood et al. The patent-pending, waste oil-to-biofuel conversion adds a new approach to waste tire recycling initiatives. Resources.

French team finds light-driven algal enzyme that converts fatty acids to hydrocarbons

Green Car Congress

For example, light-controlled catalysis allows the study of rapid enzymatic processes in real time. Some microalgae, including Chlorella variabilis NC64A and Chlamydomonas reinhardtii 137C, have the capacity to convert long-chain fatty acids to alkanes or alkenes in a process dependent on light. Photoenzymes, they note, are rare.

Argonne and NGO Energy Vision case studies demonstrate success of renewable natural gas as transport fuel

Green Car Congress

The US Department of Energy’s Argonne National Laboratory and the sustainable energy NGO Energy Vision released two case studies assessing the results of projects that were among the first to produce Renewable Compressed Natural Gas (R-CNG) vehicle fuel by using anaerobic digesters to capture the biogases from decomposing organic waste.

WSU, PNNL researchers convert algal biofuel waste from hydrothermal liquefaction into commodity using anaerobes; sewage sludge next

Green Car Congress

Researchers at Washington State University and Pacific Northwest National Laboratory have devised a method of converting a waste product generated by the conversion of algae into bio-crude into a usable and valuable commodity. Converting algae to biofuels can utilize a two-step process. —Fernandez et al. Schmidt, Marie S.
