This research aimed to optimize the experimental conditions of biodesulfurization sulfide ore and evaluate flame-retardant effect after desulfurization under optimal conditions. Six factors were determined: particle size sample, ambient temperature, rotary speed shaking table, volume bacteria liquid, concentration leaching aid (Tween80), pH value acidizing sample. Desulfurization efficiency was...

Production of renewable fuels from gasification is based on catalytic processes. Deep desulfurization required to avoid the poisoning catalysts. It means removal H2S but also organic sulfur species. Conventional cleaning consists a several-step complex approach comprising hydro-treating followed by removal. In this work, single-stage process using zinc and nickel oxide sorbent has been investig...

Several research groups have attempted to make recombinant bacteria capable of efficient desulfurization of oil fraction. The main aim of this study was to design a recombinant strain in order to desulfurize dibenzothiophen (DBT) and its components found in petroleum. In this study the pVLT31 vector harboring dszABC genes was transferred into recombinant E. coli BL21 which contained the dszD ge...
