Abstract:

Fabricate laboratory-scale experimental system for the investigation of removal of sulfur-containing compounds in two steps: catalytic reaction (HDS) and H2S adsorption.
The system can work at high pressure and temperature and continuously. The expected maximum pressure is 10 bars and maximum temperature is 4000C.
Synthesize materials for HDS reaction and H2S adsorption step.
Catalysts are Cobalt- Molybdenum (CoMo) basic with several type of supports. All catalysts are in form of pellet/granule in order to be ready for practical application.
Adsorbents are ZnO- based materials. Adsorbents are also in form of pellet/granule.
Characterization of the catalysts and adsorbents will be analyzed by several techniques such as Xray Diffraction (XRD), Low temperature N2 adsorption/desorption (BET), Scanned Electron Microscopy (SEM), etc.
Test the efficiency of the materials in removal of sulfur-containing compounds.
Catalysts and adsorbents are examined for the performance in removal of S-containing compound in the low pressure gas stream of Dinh-Co gas-processing factory. The actual gas will be taken from Dinh-Co gas processing plant. Analysis of input/output stream will be conducted using a Gas Chromatograph equipped a Mass spectrometer (GC-MS).
A laboratoryscale experimental system for the investigation of removal of sulfurcontaining. The system consist of a high pressure working fixedbed reactor, two high pressure adsorption columns for which the system can operate continuously. Temperature controllers as well as flowrate controllers are equipped in the both main units.
Procedures for producing catalysts and adsorbents.
Report on experimental data and evaluation of ability to apply the technology in treatment of sulfurcontaining compounds in practical gas from DinhCo gas processing plant.
Increased the knowledge not only for our students but also for our young staffs. They knew how to do the research in the best way, as well they can write the paper, seminar, science reports. Besides, we have the good chance to cooperate with industry, not only in this project but also in other cooperations later. This project also helps some our student have a good chance to study by AUN/SEEDNet progam. This project help Dinh Co company have new idea for H2S treatment. But the problem now they are using the other system, so they are now trying to apply the result into their company when they solve the benefit problem.
