The present invention relates to a nickel-based catalyst using hydrotalcite-like precursor and a steam reforming reaction by using the catalyst, and particularly to a nickel-based catalyst prepared by dispersing nickel uniformly onto the inner part and the surface of the support through a substitution between the magnesium and the active nickel metal and optimizing the molar ratios of nickel, magnesium and aluminum in order to utilize nickel as an active metal and a hydrotalcite-like precursor consisting of aluminum and magnesium, which shows an increased specific surface area of the catalyst and surface area of the active nickel, and thus enables the production of hydrogen-rich gas in high yield during the steam reforming reaction of LPG with superior maintenance of catalytic activity for a long period of time due to the inhibition of carbon deposition.

The present invention relates to a method for separation and recycling of pure sulfur dioxide from a gaseous mixture in the IS cycle. More specifically, the present invention relates to a method for separation and recycling of pure sulfur dioxide from a gaseous mixture in the IS cycle using an ionic liquid under a specific condition. When compared with the conventional amine-based absorbent, the use of the ionic liquid enables continuous absorption and stripping of SOeven at high temperature, and enables a reversible absorption of SOwithout loss, decomposition or degradation of a solvent due to good chemical stability, thereby enabling separation and recycling of pure SOfrom a gaseous mixture in the IS cycle.

The present invention relates to a solid oxide fuel cell for internal reforming of hydrocarbons and carbon dioxide, in particular, to a solid oxide fuel cell in which one side of solid oxide electrolyte (YSZ) is attached to an air electrode (LaSrMnO) and its other side is attached to a catalyst electrode of Ni-YSZ type or perovskite type metal oxide. The electrochemical conversion system using the solid oxide fuel cell permits the occurrence of internal reforming of hydrocarbons and carbon dioxide concomitantly with the coproduction of a syngas and electricity, and overcomes the shortcomings associated with the catalytic deactivation due to carbon deposition and the high-energy consumption.
