Abstract: The present invention relates to a method of preparing a dry reforming catalyst having a novel structure for syngas production. In particular, the method comprises: an LDH preparation step of producing a layered double hydroxide (LDH) by using Ni and a divalent cationic metal more difficult to reduce than Ni; and a catalyst preparation step of thermally treating the prepared LDH to cause only Ni, a divalent cation relatively easier to reduce, to be eluted on the surface. The present invention may produce a Ni catalyst having a novel structure by eluting only Ni from the LDH due to difference in reducing power. Also, the catalyst of the present invention has Ni evenly distributed on the surface of the LDH and also firmly bonded to the lattice of the LDH, and therefore, has excellent effects of reducing carbon accumulation and catalyst enlargement when applied to a dry reforming process for syngas production.

Abstract: The present invention relates to catalysts for heterogeneous hydrogenation of oxo process aldehydes. The problem addressed by the present invention is to develop a catalyst containing neither chromium nor nickel. In addition, the present invention is intended to enable the economically viable hydrogenation of aldehyde mixtures originating from industrial oxo processes on the industrial scale. For this purpose, the catalyst should not be reliant on costly precious metals such as Ru, Pd or Pt. This problem was solved by omitting chromium and nickel in the preparation of a conventional Cu/Ni/Cr system, such that a catalyst wherein only copper, not chromium or nickel, is present as a hydrogenation-active component on a support material thereof, is obtained. What is surprising in the present invention is that a functioning catalyst for the intended purpose still arises even though two of three hydrogenation-active metals are omitted. However, this requires as necessary conditions that a support material used is silicon dioxide and that the content of Cu and SiO_2 in the active catalyst is set accurately within very rigid limits.
