Thoughts on the oil to gas conversion

Abstract

According to the results of the pyrolysis experiments carried out on both crude oil and individual compound such as n-hexadecane, oil-hydrocarbons transform into hydrocarbon gases at temperature of higher than 160 °C, and at vitrinite reflectance of higher than 1.5%. Cracking of the oil into gas is retarded by the pressure increase and the effect of water present in natural environments of thermal alterations. Moreover, gases are formed from oil resins and oil asphaltenes, than from the hydrocarbons of the crude oil.
