[0051] 1. Preparation of fast ion conductor particle catalytic electrode:

[0052] ① The chemical reagents used are of analytical grade without further purification.

[0053] ②Preparation process:

[0054] 50-300g of zirconium chloride (ZrOCl 2 .8H 2 O) be dissolved in 150-300ml distilled water, drip in the 30% ammonia solution drop by drop, and stir, keep pH value between 9-10, let stand and precipitate. The precipitated hydroxide is then washed until chloride ions are removed. The presence of chloride ions has a strong negative effect on the activity of the catalyst. Put it into a drying oven after washing, and dry it at a temperature of 120°C for 24 hours to obtain zirconia powder. The zirconia powder was immersed in a 0.8 mol / L sulfuric acid solution for 9 hours. Then wash and dry in vacuum to obtain acidified zirconia powder for future use.

Abstract

The invention provides an electrochemical catalysis diesel oil desulphurization method at normal temperature and pressure. The method uses the oxyradical prepared by electrochemical catalytic oxidation as a catalyst, the catalyst and the diesel oil and gasoline thiophene are subjected to a catalytic oxidation reaction, and the reaction produces acid gas and discharges the acid gas, so that the low-sulfur oil product with total desulfurization rate about 100% is obtained. The method includes making the oil to be desulfurated enter a rapid-ion-conductor particle catalytic electrode chamber 5 from an oil inlet 1 through oil distribution net 3, uniformly sprinkling the oil on a rapid-ion-conductor particle catalytic electrode by the oil distribution net 3 to react for 5-6 hours, filling the rapid-ion-conductor particle catalytic electrode chamber 5 with diesel oil with the increasement of the oil inflow, preparing the acid gas by the sulphur in the oil in the desulfurization, discharging the acid gas into a 30% sodium hydroxide solution absorption cell through a gas discharge outlet 2, preparing sodium sulfate by acid gas and sodium hydroxide, preparing solid sodium sulfate after filtration, recycling the filtering medium, using the recycled filtering medium as an acid gas absorption medium after replenishing sodium hydroxide, and pumping the desulfurized oil into a petroleum products tank by an oil-filter screen 6.
