AB  - Hydrodynamic Cavitation (HC) offers an attractive platform for intensifying 
      oxidative desulphurization of fuels. In the first part of this work, we present 
      new results on oxidising single ring thiophene in a model fuel over the extended 
      range of volume fraction of organic phase from 2.5 to 80 v/v %. We also present 
      influence of type and scale of HC device on performance of oxidative 
      desulphurization. Further experiments revealed that oxidising radicals generated 
      in-situ by HC alone were not able to oxidise dual ring thiophenes. External 
      catalyst (formic acid) and oxidising agents (hydrogen peroxide, H(2)O(2)) were 
      therefore used with HC. Based on our prior work with acoustic cavitation (AC), 
      the volumetric ratios for H(2)O(2) and formic acid were identified as 0.95 v/v % 
      and 6.25 v/v % respectively. The data of oxidation of dual ring thiophenes with 
      n-dodecane and n-hexane as model fuels and typical transport fuels (diesel, 
      kerosene, and petrol) using these oxidant and catalyst is presented. The observed 
      performance with HC was compared with results obtained from a stirred tank and AC 
      set-up. The presented data indicates that HC is able to intensify oxidation of 
      sulphur species. The presented results provide a sound basis for further 
      developments on HC based oxidative desulphurization processes.
