OXIDATION OF PETROLEUM HYDROCARBON IN LIQUID PHASE

摘要

Oxidation of n-Paraffins at a low pressure of Oxygen and a low temperature in the liquid phase has been carried out. The role of the Catalyst to help the Oxidation process has been investigated. The catalyst used in the process is Cobalt Naphthenate. Products derived from the so called catalytic oxidation of a n-Cetane as reference and n-Hydrocarbons extracted from gas oil as main feed-stock includes: Hydroperoxides converting to Aldehydes, Ketones, Alcohols and Carboxylic Acids. It was found that oxidation of branched chain hydrocarbons at similar conditions results in the production of more hydroperoxides. In any case, the amount of hydroperoxides produced which remains intact at the end of the process is insignificant. When oxygen pressure in the reactor increases and temperature is also elevated, almost all the hydroperoxides produced will decompose, yielding other oxygen containing compounds as mentioned above. In a different process the joint effect of SO_2 and O_2 on the n-Paraffin Hydrocarbons derived also from gas oil while Gamma-rays acting as catalyst are also studied.
