ABSTRACT

Soil samples collected in South Wales was extracted and asphaltenes were precipitated from the extract. The asphaltenes were then subjected to hydropyrolysis to determine the percentage yield of hydrocarbon from asphaltene matrix. Open column chromatography was performed on asphaltenehydropyrolysate gave a percentage recovery of 92 %, suggesting that this process is a veritable tool for the release of bound hydrocarbons in asphaltene matrix. The mass balance for hydrocarbon distribution is consistent with literature
