Study of Rice Bran Biodiesel Engine Emissions Using Non-thermal Plasma Assisted Catalyst System
The main components of the Rice bran biodiesel (RBD) sample were detected using gas chroma-tography-mass spectrometry. The bench test experiment was carried out, and the reduction of diesel engine harmful emissions by non-thermal plasma with assisted catalyst (NPAC) system operating on both RBD fuel and NO 0 diesel fuel had been investigated. Scanning electronic microscope and X-ray energy spectrometer were used to detect the surface structure and chemical component of particulate matter samples from the exhausts of diesel engine. Results showed that the particulate matter was decreased remarkably, and the diameter of the particulate matter was smaller and looked more compact; NPAC system operated by oxidation of NO to NO2 in the plasma discharging zone, followed reducing NO2 by reaction with reductive radicals and partially particulate matter over the catalyst. The results of elemental analysis revealed that NTP was unaffected by exhausts impurity such as sulfur, and was one promising technology for diesel engine emissions reduction.
