摘要： Disclosed are a catalyst for preparing synthesis gas from natural gas and carbon dioxide, and a method for preparing the same. More particularly, a combined reforming process is performed as an economical way of using carbon dioxide, wherein steam reforming of natural gas is carried out simultaneously with carbon dioxide reforming of methane in such a manner that a predetermined ratio of carbon monoxide/carbon dioxide/hydrogen (H2/(2CO+3CO2)=0.85-1.15) is maintained. In this manner, the catalyst is used to prepare synthesis gas suitable for methanol synthesis and Fischer-Tropsch synthesis. Disclosed also is a method for preparing synthesis gas on a specific catalyst consisting of Ni/Ce/MgAlOx or Ni/Ce-Zr/MgAlOx. The catalyst is inhibited from deactivation caused by generation of cokes during the reaction as well as deactivation caused by reoxidation of nickel with water added during the reaction. Therefore, the catalyst shows excellent activity as compared to other catalysts for use in combined reforming.

摘要： Disclosed is a method for methanol synthesis using synthesis gas obtained from reforming of natural gas with carbon dioxide. First, synthesis gas is obtained from steam carbon dioxide reforming of methane, in which steam reforming of natural gas is carried out simultaneously with carbon dioxide reforming of methane, by using a catalyst (Ni/Ce/MgAlOx, or Ni/Ce—Zr/MgAlOx) and processing condition capable of maintaining a predetermined ratio of carbon monoxide, carbon dioxide, and hydrogen [H2/(2CO+3CO2)=0.85-1.15] Next, methanol synthesis is carried out by using the obtained synthesis as and a catalyst system suitable for methanol synthesis with minimum byproduct formation (a catalyst system including a Cu—Zn—Al oxide containing CuO, ZnO, and Al2O3 at a predetermined ratio in combination with a cerium-zirconium oxide obtained by a sol-gel process). In addition, unreacted synthesis gas remaining after the operation of methanol synthesis is recycled efficiently to improve the carbon availability (methane and CO2 availability) and energy efficiency in the overall process.

摘要： Disclosed herein is a thrust fin for ships which recovers lost energy caused by rotational flow generated behind a propeller, and converts it into thrust. The thrust fin of the present invention has a simple shape, enhances propulsive efficiency of the ship, and can be applied to a real ship thanks to the simple installation thereof, to maximize thrust of the ship. The thrust fin is mounted to a front portion of the rudder of the ship such that left and right sides of the thrust fin, which are integrated with each other into a single body, are asymmetrical. A vertical position, at which the thrust fin is mounted to the rudder, is at an optimum position as determined in consideration of the shape of the rudder and hydrodynamic characteristics.
