Abstract: Disclosed is a method of producing a propylene-based copolymer using a solid catalyst including a carrier, produced by the reaction between dialkoxy magnesium and a metal halide, a titanium halide, and an organic electron donor. According to the disclosure, it is possible to produce a propylene-based copolymer having a high comonomer content and a low amorphous content while maintaining catalyst activity at a highly level and dramatically reducing agglomeration of polymer particles during the production of the copolymer.

Abstract: Disclosed are a dry reforming catalyst having high activity and long-term stability, and a method for preparing the dry reforming catalyst. A sol-gel reaction is performed at the interface of a catalyst for sol-gel reaction in the form of micelles to form silica particles having pores. In addition, catalyst particles of nickel or nickel oxide are formed in voids or pores of silica by using the difference in solubility in a gel state of the silica.
