NOVELTY - Preparation of environment-friendly gasified oil involves adding mixture of deodorant and main material to a mixture of heat-increasing agent, smoke suppressant, emulsifier and auxiliary material, maintaining at 30-40 degrees C, and stirring for 30-45 minutes; adding mixture of accelerator, combustion improver, dispersant and catalyst, maintaining at 40-50 degrees C, and stirring for 30-45 minutes; measuring pH of the solution, adding pH regulator, and stirring for 10-15 minutes until pH of the solution is 7.5-8.5; and discharging obtained material.    USE - Method for preparing gasified oil (claimed).    ADVANTAGE - The method is simple. The obtained gasified oil has stable combustion performance, combustion temperature of 1100 degrees C, combustion heat value of 8500 kJ/kg, and low fuel explosion lower limit.    DETAILED DESCRIPTION - Preparation of environment-friendly gasified oil comprising (wt.%) main material (65-85), auxiliary material (20-33) and additive (1-3), in which the additive comprises emulsifier, smoke suppressant, dispersant, deodorant, heat-increasing agent, pH regulator, catalyst, and/or combustion improver, involves:    (A) placing deodorant and main material in a reaction container, and stirring;    (B) placing heat-increasing agent, smoke suppressant, emulsifier and auxiliary material in a reaction container, stirring for 30-45 minutes, and gradually heating to 40-45 degrees C until homogeneous;    (C) placing accelerator, combustion improver, dispersant and catalyst in reaction container, stirring for 30-45 minutes, and gradually heating to 40-45 degrees C until homogeneous;    (D) adding the mixture obtained in step (A) to the mixture obtained in step (B), maintaining at 30-40 degrees C, and stirring for 30-45 minutes;    (E) adding the mixture obtained in step (C), maintaining at 40-50 degrees C, and stirring for 30-45 minutes;    (F) measuring pH of the solution, adding pH regulator, and stirring for 10-15 minutes until pH of the solution is 7.5-8.5; and    (G) discharging obtained material.    The main material comprises methanol, waste oil in chemical production industry, residual oil, and/or recycled oil. The auxiliary material comprises diesel oil, kerosene, acetone, Xanthoceras sorbifolia oil, ethanol, and/or water.
