Abstract: Provided is an electrode for electrolysis and a preparation method of the same. The electrode for electrolysis has an improved needle-like structure of a rare earth metal compared to conventional electrodes, and thus detachment of catalytic materials is reduced, so that the electrode is excellent in durability such as exhibiting stable performance even in a reverse current flow. Further, since the electrode for electrolysis has a low overvoltage value, an overvoltage required amount of the electrolytic cell can be remarkably reduced. In addition, an electrode for electrolysis having the above effect can be prepared without introducing additional precursors or changing manufacturing facilities.

Abstract: The present invention relates to a method of producing ethylene by separately collecting ethane and ethylene which are by-products of a propylene preparation process using propane dehydrogenation reaction and also combining an existing propylene preparation process with a process of converting ethane to ethylene. According to the present invention, valuable ethylene may be produced by converting most of ethane and ethylene, i.e., by-products of a propane dehydrogenation process, into ethylene without using the ethane as fuel, thereby improving process economic efficiency. Furthermore, a product line in the process of propane dehydrogenation reaction may be changed from a propylene product alone into two products, i.e., propylene and ethylene, and thus the operating conditions of a propylene dehydrogenation reactor and the operating conditions of a de-ethanizer may be adjusted according to the market situation, thereby increasing the production proportion of a favorable product line.
