Advantages

Vitrain has higher moisture and volatile matter than durain, while durain has higher ash and fixed carbon content

Vitrain contains more vitrinite and less inertinite

Main oxygen-containing functional groups in order of decreasing content: C-O, COOH, C=O

Fatty side chains in order of decreasing content: CH₂, CH₃, CH
