Singaporean researchers discover air pollution insights for both fossil and biodiesel

April 22, 2020 |

In Singapore, a team of researchers from Yale-NUS College, in collaboration with scientists in Sweden, has found that bisulphate species in the exhaust stream are strongly connected to decreasing the effectiveness of exhaust remediation catalysts in diesel engines. Their findings pave the way for synthesizing more sulphur-tolerant catalysts and developing regeneration strategies for catalyst systems on diesel-powered freight vehicles. This could lead to lower emission of highly toxic nitrogen oxides from diesel engines, hence reducing pollution.

With greater insight into the way sulphates affect catalysts, future work can be done to investigate how the negative effects can be mitigated. Additionally, the findings regarding sulphates may also be applied to other studies on the impact of phosphorous and phosphorous oxides, present in biodiesel fuel, on catalyst performance. This could lead to the creation of more effective catalysts for biodiesel-powered engines.
