Par tial oxidation reaction char acter istics of oil sludge (I)

resource utilization of oil sludge by oxidative
thermal decomposition, the reaction kinetics and
products analysis of pyrolysis in the presence of
oxygen are studied. A three-reaction model is
proposed for the oxidative thermal decomposition
of oil sludge. The first reaction is pyrolysis
reaction without oxygen, while the second and
third reactions are oxidative reactions. This model
can be used for the situation with concentration of
oxygen below that of air. In the accumulate
gaseous product, CO2 has the highest concentration.
The temperature ranges corresponding to the
maximum production rates of CO2 and of CO, HCs
(hydrocarbons) and H 2 are 788 ~ 813 K and 713 ~
738 K, respectively. The distillation characteristics
of liquids from the oxidative thermal
decomposition of oil sludge are closed to the
commercial gasoline and diesel oil.
