With the catalytic aquathermolysis process, an appropriate quantity of a catalytic system or catalyst mixture is introduced into the oil reservoir simultaneously with a steam at high temperature . There are some vital steps to be observed with this technology. The thermolysis process and the effect of steam at high temperature (i.e. aquathermolysis) are responsible for deriving the overall process energetically. Thus, the key role of the aquathermolysis aspect is to break down the heavy Difloxacin in the oil to smaller molecules by the combined effect of steam and heat.
