The present invention relates to a structured catalyst for reforming of gasoline and a method of preparing the same, more particularly to a structured catalyst for reforming of gasoline for fuel-cell powered vehicles prepared by wash-coating the transition metal based reforming catalyst on the surface of the ceramic honeycomb support wash-coated with sub-micron sized alumina or its precursor to sufficiently increase the effective surface area and the performance of the catalyst and a method of preparing the same.
Abstract:
Disclosed are a pyrrolidinium type sulphonated zwitterion, a method of preparing the same, a lithium salt prepared by using the same, a method of preparing the salt, an electrolytic composition containing the salt and a lithium secondary battery including the electrolytic composition. Since the pyrrolidinium type sulphonated zwitterions prepared according to the invention are thermally and electrochemically stable, the lithium salt prepared by using the same exhibits a lower hygroscopicity than the conventional lithium salts and strong thermal and electrochemical stabilities. When the lithium salt of the invention is dissolved in an organic solvent independently or together with the ionic liquid, excellent conductivity and electrochemical stability are exhibited. Accordingly, the lithium salt of the invention is very suitable for the electrolyte of the lithium secondary battery.

Abstract:
The present invention relates to a Ni-based catalyst for preparing syngas and a tri-reforming reaction of methane using the catalyst, particularly to a Ni-based catalyst, where an active ingredient (a nickel) is impregnated in a zirconia support and the zirconia is doped with a yttrium and a metal selected among a lanthanum and an alkaline earth metal to distort the crystal lattice of the zirconia, to facilitate the transfer of oxygen ion and to increase the storage and supply of oxygen, thus inhibiting the carbon deposition on the active nickel metal and maintaining the activity of the catalyst. Particularly, if the catalyst herein is used for the tri-reforming reaction of methane where a mixture of carbon dioxide, oxygen and steam is used as an oxidant, the molar ratio of hydrogen and carbon monoxide (H2/CO) in the syngas may be selectively controlled.
