At present, there are two kinds of processes in the aspect of deep desulphurization, name hydrodesulphurization and non-hydrodesulphurization. Despite the facts that hydrodesulphurization process is characterized by pronounced desulphurization effects good product quality, yet it also has such demerits as harsh operating conditions and a fa amount of hydrogen as well as high costs. Sulfur content distribution in fuel products desulphurization processes for producing low sulfur fuels via ultrasound are introduce the thesis. H202 has been used as this experiment's oxidant. The desulphurization resu different concentration H202 shows that the sulfur removal rate of30%, H202 was the 1 effective. At the same time, desulphurization result of inorganic acid catalyst indicates the desulphurization rate of sulfuric acid phosphate slightly higher. And two mixedratios with the proportion of 1 : 1 are the best. The rate of desulphurization will be h: after adding the metal catalyst.
By analyzing the nature of diesel samples, which is before and after desulphurization that diesel via ultrasound with the acid catalyzed oxidation and absorption desulphuri, process. Its sulfur content, acidity, density decreased the quality of after desulphurt can reach standards of the international vehicle clean diesel quality.
The results of the experiment show that under the power ultrasound, the optimal opt conditions of H202-mixing acid system in the laboratory is the quantity of the ox: system: oil is 3:l00(the volume ratio of oxidative reagent and oil); H202: Mixe (volume ratio ) = 1: 1; ultrasound time is 9 min. Adsorbent: activated carbon; adsorbent: o (volume)= 1:1. Sulfur content dropped from 699.12 to 16.08, the desulphurization rate 97.7%, and yield of oil is 91.2%.
