The present disclosure relates to a process for recovering vanadium in the form of iron vanadate from a gasifier slag. The process comprises pulverizing the slag to obtain pulverized slag (). The pulverized slag () is soaked in water () and an alkali salt () to obtain a slurry (), followed by roasting the slurry in the presence of air to obtain roasted slag () which is leached () to obtain a first solution (). The first solution () is heated at a temperature in the range of 60° C. to 80° C. while adding an iron salt () in an amount in the range of 10 wt % to 60 wt % at a pH in the range of 4 to 10, to obtain a second solid residue () which is dried to obtain iron vanadate ().

The present disclosure provides a method for catalytic conversion of waste plastic into liquid fuel. The method comprises thermally decomposing the waste plastic at a temperature in the range of 350 to 650&#xb0; C. and under a pressure in the range of 0.0010 psi to 0.030 psi, to obtain a gaseous stream. The gaseous stream is further subjected to four stage sequential cooling to a temperature in the range of &#x2212;5 to &#x2212;15&#xb0; C. to obtain a gas-liquid mixture comprising a gaseous fraction and a liquid fraction. The gas-liquid mixture is fed to the gas-liquid separator to obtain the gaseous fraction comprising C1 to C4 hydrocarbons and the liquid fraction comprising liquid fuel. The method of the present disclosure is simple, economical and energy efficient, which provides a high value liquid fuel with enhanced yield.
