FTIR Analysis of Surface Functionalities on Particulate Matter Produced by Off-Road Diesel Engines Operating on Diesel and Biofuel

Popis výsledku v původním jazyce

Multicomponent composition of diesel and biofuel particles reveal the chemistry related to a variety of functional groups containing carbon, hydrogen, oxygen, sulfur, and nitrogen. The most intensive functionalities of diesel particles are saturated C?C?H and unsaturated C=C?H aliphatic groups in alkanes and alkenes, aromatic C=C and C=C?H groups in polyaromatics, as well as sulfates and nitrated ions. The distinguished features of biofuel particles were carbonyl C=O groups in carboxylic acids, ketones,aldehydes, esters, and lactones. NO2, C?N and -NH groups in nitrocompounds and amines are found to dominate biofuel particles. Group identification is confirmed by complementary measurements of organic carbon (OC), elemental carbon, and water-soluble ion species. The relationship between infrared bands of polar oxygenated and non-polar aliphatic functionalities indicates the higher extent of the surface oxidation of biofuel particles. Findings provide functional markers of organic surfa
