要求： 1) TOEFL （》70 for IBT）GRE is not required, so without GRE is OK 2) 本科或研究生均可申请 3）适用专业：化学工程，工艺；化学 （分析，无机，生化，物化）； 材料 （无机，聚合/高分子，纳米，复合材料）；农业系统工程 （生物能源，可再生材料）， 炭/碳材料 。有炭材料，炭吸附剂制备经验，优先。 4）研究背景：炭材料制备, 生物质热解，材料表征，表面化学 5）仪器操作经验： 热解，气氛电炉，气液相吸附分析（UV-Vis, BET比表面, FTIR远红外, 表面电性能, SEM/TEM, 统计分析）. 联系方式： 发送你的简历到邮箱： zhengrong.gu@sdstate.edu 寻求网络面试的可以加我： lxqguzhr@hotmail.com This project will be sponsored by USDA for " developing value added carbon materials from carbon rich residues of process, which is designed to produce biorenewable energy or/and biofuel". (details in below) I am PI for this project and suggest focus on activated carbon or other carbon adsorbents. But I am also open for other advanced carbon materials. The Postdoc position will start after Jan 2011. 1) Evaluate the application of industrial standard methods, chemical catalytic activation using conventional catalysts (ZnCl2, NaOH or KOH, H3PO4) and physical activation using steam or carbon dioxide, to effectively activate the pyrolytic generated biochar starting material. 2) Explore the application of the following new innovative activation processes for the purpose of effectively activating the pyrolytic generated biochar starting material: supercritical water (SCW) activation, MW activation in the presence of conventional catalysts or steam or carbon dioxide, other chemical or physical treatments and surface modification methods. 3) Quantify the thermodynamic and reaction kinetics for those activation technologies that have the most optimistic commercialization potential. This will provide the necessary information to be able scale up for commercialization. May I please you send me your consideration about your future research in my group, so what will be your stage targets in 1st, 2nd and 3rd year. What kind equipment/instruments/methods will be used? You could find some instruments available in my lab or other SDSU's labs. in the equipments list in below. One micropore analyzer (BET surface with N2 and vapor adsorption) One NIR for water, protein, oil content assay One sieve and shaker system for particles sizing and separation One dry milling (roller mill, hammer mill, pan mill) lab. One Tube furnace (300~1200 Celsius) with automatic control and gas protection functions will be used to carry out physical or chemical activation. One muffle furnace equipped with air tight internal steel reactor for biomass pyrolysis is being used to produce biochar and biooil for US Army Jet fuel project. The biochar will be supplied as feed materials for this proposed project. One microwave pyrolysis reactor system (100~700 Celsius) is being used to produce biochar and biooil for US Army Jet fuel project. The biochar will be supplied as feed materials for this proposed project. One ultraconic wave system (immersion ultrasonic horns 50 to 500 W/cm2) will be used for ultrasonic activation or treatment of carbon materials. One ozone system will be used for ozone activation or treatment of carbon materials. Two hydrothermal reactors systems (0 ~ 40 MPa) will be used to carry out supercritical water activation of biochar. One Shimadzu UV-Vis 2450 spectrophotometer will be used for methylene and iodine adsorption assay. One Angilent GC system with CO2 and O2 assay columns and a H2 flame detector will be upgraded. The GC will be used to monitor reaction kinetics and thermodynamic properties of activation processes. One differential scanning calorimetry (DSC) will be used to detect thermal stability, surface volatile groups or components of volatiles in biochar and activated carbon samples. Two filtration systems (5~300 psi and 200~1500 psi) and one Biorad Maximizer FPLC (fast flow chromatography can run at 80 ml/min 6.6 Mpa) will be used for evaluate downstream application of activated carbon developed in this projects. Two Angilent HPLCs will be used to analyze adsorption ability of activated carbons prepared in this proposed project. In Principle investigators’ laboratory also has one centrifuge machine, three air convection ovens, one pilot single screw extruder, one fluorometer, several balances and one solvent evaporation system. On campus of South Dakota State University (laboratories of Chemistry and Electric Engineering) X-Ray diffractometer, XRD will be used to analyze ash contents and compositions, and carbon crystal structure in biochar and activated carbon samples. Scanning electron microscopy (SEM) will be used to characterize surface properties and exposed pore structure of carbon materials developed in this proposed project. Fourier Transform Infrared spectroscopy (FTIR) will be used to characterize surface groups of carbon materials developed in this proposed project. 100 ~ 400 MHz variable-temperature solid-state nuclear magnetic resonance (NMR) will be used to obtain a closer look at the adsorption sites on carbon material after activation (when this information is necessary) The North Central Agricultural Research Laboratory (USDA) Rotap shaker with standard sieving screens will be used to measure particles size distribution and fractionate carbon materials into different fractions with specified particle size. If you agree to prepare a short overview (in two weeks) of your future research in my group (in one ~ two week) , I will be glad to review your sub-proposal and give you a online or telephone interview after discussion with other Co-PIs. |
