The effects of modification with promoters (Ru, Zr, Mn and K) on the properties of cobalt-based catalyst in CO hydrogenation were investigated by TPSR technique. The catalysts prepared by sol-gel method were characterized by BET, TPR and H 2 -TPD. The effect of promoters was observed to have a profound impact on the physicochemical and catalytic properties of catalysts. Addition of Ru, K and Zr promoters to 30Co/MgO (30CM) facilitates the reducibility of catalyst. Mn addition improves the dispersion of metal clusters leading to a decrease in average cobalt crystallite size. Among all catalysts, 30Co-Mn/MgO (30CMM) and 30Co-Ru/MgO (30CRM) demonstrate the high reactivity and the maximum rate for methane formation. This could be attributed to the improvement of carbon monoxide chemisorption on high metal surface area of 30CMM and 30CRM catalyst. The change in physical and chemical properties of catalysts could be elaborated by the structural and electronic effects of promoter. Manganese effectively promotes cobalt supported magnesia catalyst by enhancement the C 5+ selectivity.

In this work, the Ni-based catalysts (10 wt.%Ni/Al 2 O 3 -MgO and 10 wt.%Ni/MgO) were synthesized by sol-gel method. Each catalyst was prepared as catalyst pellets and catalyst-coated plate, stainless steel plate coated with catalyst. The catalyst-coated plates were fabricated using spray coating. The dry methane reforming (DMR) performances of catalyst-coated plate were investigated and compared with DMR performances of catalyst pellets. As the mass transfer was improved, the methane consumption rate per gram of catalyst coated onto metal plate was ten times greater than those of catalyst pellets approximately. The carbon deposition was also significantly prevented when the catalyst was constructed as a thin-film layer on the plate under our developing condition. Therefore, this catalyst-coated plate can be further developed for multichannel reactor.

Fischer-Tropsch synthesis (FTS) is a key performance in the gas-to-liquid (GTL) process. This research is focused on the effect of Mn promoter on cobalt supported MgO catalyst in Fischer Tropsch reaction. 30 wt.%Co/MgO (30CM) and 30 wt.%Co/MgO-x wt.%Mn (30CM-x%Mn) were synthesized as an unpromoted and a promoted catalyst, respectively. The effect of Mn promoter and its loading on physical and chemical properties of catalysts were investigated by BET, H 2 -TPR, H 2 -TPD and TPSR techniques. The catalytic performance of all catalysts was explored in FTS. The addition of Mn promoter deliberately promotes the FTS activity as well as selectivity towards long chain hydrocarbons in the range of diesel product. Mn promoter beneficially improves the cobalt dispersion and decorating cobalt surface. This behavior is elucidated that Mn is functionalized in term of structural and electronic promoter.

In this paper, proton conducting composite membranes of Nafion® -mordenite for direct methanol fuel cell (DMFC) were prepared using solution casting method. Mordenite, used as inorganic filler, was incorporated into Nafion polymer in order to improve membrane properties for DMFC application. Effect of solution casting temperature on resulting composite membranes was focused. The temperature of the membrane preparation was varied from 80 to 120° C. Properties and morphology of the resulting membranes including solubility, water uptake, ion - exchange capacity were investigated and reported. It was found that composite membrane prepared at 100° C gave the most alcohol resistance and mechanical stability membrane with 0.59% soluble. Furthermore, it gave highestion - exchange capacity, 0.10 meq?g-1, which is 33% and 98% higher than the membranes prepared at 80° C and 120° C respectively.

It founded that crude palm oil, CPO, could be changed to Bio-hydrogenated Diesel, BHD, which has a potential to replace the petroleum-derived diesel. Therefore, techno-economic feasibility of BHD production for Thailand was studied with a capacity of 1 million liters per day (MLD) of BHD. In this work, a conceptual design of BHD process was developed by using process simulator, ASPEN Plus. Calculation of mass and energy balance, equipment sizing and cost estimation in five major unit operations were performed. The total capital investment was calculated and used for economic analysis to estimate the return on investment, price value and payback period. The results showed that total capital investment cost was 174.34 millions USD with 1 MLD of BHD, PBP was 5 years with 17.02% ROI. BHD price of 1.16 USD/L. © (2014) Trans Tech Publications, Switzerland.

Performance of direct methanol fuel cell (DMFC), using polymer composite membrane, can be directly affected by membrane properties, including permeability, proton conductivity and membrane thickness. In order to obtain high DMFC performance, methanol permeability of the membrane should be low, while keeping high proton conductivity. This may be achieved by modification of incorporating inorganic filler into high proton conducting membrane. In this work, the analytical modeling for DMFC performance prediction was developed to be a guideline for Nafion based membrane improvement. Methanol permeability and proton conductivity were set at 0.30-5.60 cm2 ×S-1 and 0.08-0.15 S×cm-1 with the thickness of 25-1000 μm. The results show that DMFC performance strongly depends on the methanol permeability especially with thin membrane giving maximum power density of 1034 and 100mW×cm-2 at the permeability of 0.30 and 5.60 cm2 ×S-1, respectively, with thickness of 45 μm, while with thick membrane the permeability has negligibly effect. However, the proton conductivity mainly affects DMFC performance only with thick membrane as a result of ohmic resistance. © (2014) Trans Tech Publications, Switzerland.
