Nitrogen oxides, also known as NOx, form when fossil fuels burn at high temperatures. When emitted from industrial sources such as coal power plants, these pollutants react with other compounds to produce harmful smog.
Researchers at PNNL have developed a model that predicts outcomes from the algae hydrothermal liquefaction process in a way that mirrors commercial reality much more closely than previous analyses.
Researchers at PNNL and their collaborators have made a significant improvement to a catalyst that is more rugged and can reduce tailpipe pollution at lower temperatures than existing methods.
Several years ago, a relatively new catalyst for vehicle emission control began showing failure. A team at PNNL found that this seemingly suicidal catalyst wasn’t actually self-destructing but was the victim of an external assailant.
Researchers developed a new hybrid catalyst that achieved chemo-selective and site-selective hydrogenation of aromatic molecules under low pressure of dihydrogen and mild temperature.
