n-heptane skeletal isomerization on zeolite beta that platinum and iron were loaded on was investigated. This catalyst inhibited cracking products due to β scission and produced isomer selectively. Some characterizations indicated that platinum in the catalyst would be highly dispersed when iron was coexistent on zeolite. Loading of both platinum and iron were decreased by optimization. The optimized catalyst showed raised conversion but retained remarkable selectivity.

To estimate the positions of Brönsted acid sites on ITQ-21 containing Al atoms (Al-ITQ-21), the physicochemical and catalytic properties of Al-ITQ-21 as a solid acid catalyst were investigated.  The multinuclear solid-state nuclear magnetic resonance (MAS NMR) spectra of ²⁷Al and ¹H of Al-ITQ-21 having several concentration of Al were measured, along with the NH₃ temperature programmed desorption spectra, while the conversion of n-heptane was examined over Al-ITQ-21 having several concentrations of Al.  The positions of the Al atoms in the Al-ITQ-21 lattice were limited by measuring ²⁷Al MAS NMR spectra.  This limitation made the designation of oxygen atoms bonded to acidic protons identify by measuring both spectra of the NH₃ temperature programmed desorption and ¹H MAS NMR.  Furthermore, the total reaction rates for the conversion of n-heptane on different Brönsted acid sites were determined.

In recent years, ammonia has been widely considered as an attractive hydrogen carrier which can supply hydrogen to fuel cells by thermal decomposition. In this report, catalytic ammonia decomposition over Ni/BaCe_0.75Y_0.25O_3-δ (Ni/BCY) was systematically investigated. The BCY support was prepared by citric acid complex method, and Ni was loaded by impregnation. The effects of various parameters, including the calcination temperatures of the BCY support and catalyst, the Ni sources for Ni impregnation, and the reduction temperature of the prepared catalyst, on the catalytic activity of the catalysts was evaluated. The maximum of ammonia conversion rate at 550 ºC was ca. 93% over the optimized Ni/BCY catalyst. Based on the experimental results, a mechanism for the high catalytic activity of Ni/BCY for ammonia decomposition was proposed.

Ni-SDC (samaria-doped ceria) cermet was prepared by changing SDC particle size and Ni content, and I-V and AC impedance measurement were conducted to evaluate the electrochemical processes that influence the performance of the anode. It was found that large SDC particles were effective in reducing ohmic overpotential even with low Ni content, and that the conductivity change in the anode with Ni content can be explained by percolation theory.

Supported Ni catalysts have been prepared in-situ starting from layered double hydroxides (LDHs) as the precursor and tested for the partial oxidation of methane to synthesis gas. Supported Ni catalysts were prepared from LDHs partially substituted with Ni as the precursors (Ni/Ca/Al and Ni/Mg/Al-LDHs), and the activities were studied in relation to the structure of the catalysts and compared with those prepared by the impregnation method. Ni/Ca–Al was easily reduced to form active Ni metal particles in situ (under reaction mixture flow (CH₄ + O₂ around 773 K)) and showed a high activity and selectivity to synthesis gas production.

Autothermal reforming of discarded edible oil was carried out by using Ni- and Ru/Al₂O₃ catalysts. When the reforming was made at 2.6 of S/C and 0.6 of O/C around 650 ^oC, the gasified conversion and hydrogen content showed 60~70 % and ca. 60 %, respectively. Thus the hydrogen production from soy bean oil could be made at low S/C. It was conjectured that cracking of the oil might take place in the presence of oxygen during the reforming.

The catalyst for producing aromatic hydrocarbons from bio-oil which is prepared by flash pyrolysis of the woody biomass was examined. The feedstock was prepared by mixing guaiacol (bio-oil model compound) with sulfur and nitrogen compounds. Among various supports, silica supported CoMo sulfide catalyst gave aromatic hydrocarbons selectively. However, deactivation of deoxidization activity of guaiacol was observed. When a silica supported catalyst was used with an alumina supported catalyst, aromatic hydrocarbon was selectively obtained without degradation of deoxygenation activity.

In order to produce chemicals and liquid fuels from cellulosic biomass, importance of the high efficiency of cellulose saccharification process is growing. Ionic liquid(IL)  as a solvent soluble cellulose under mild conditions has attracted many attentions, but using IL effect heavy load on environment because anion side of IL is composed of a halogen ion. In purpose of this study is to synthese clean and efficient IL catalytic system. By introducing the acidic ions to promote saccharification of cellulose instead of halogen ion, "Functionated IL" is developed. It catalyze the hydrolysis of cellulose and generate glucose with high selectivity.

Increasing global demands for fuels, the tightening of environmental regulations and the optimization of refineries has led to an increasing demand for efficient catalysts testing capacity. High throughput catalyst testing is a time-efficient approach for meeting this demand.  In this paper we present a joint case study about the parallel screening of different residue hydrotreating catalyst systems using a 16-fold trickle-bed reactor unit. In order to optimize the residue hydrotreating catalyst system, different combinations as well as single catalysts were tested.   We will discuss recent study results including the determination of composition and properties change of oil stream along the axis of the reactor length through the catalyst zones as well as correlation between the reactor packing and HDN, HDS and other performances.
