Abstract: A method for enhancement of adhesive force between a matrix and a catalyst by forming an adhesion layer on a surface of the matrix to which the catalyst is adhered using a catalyst, more preferably, the same material as a carrier of a catalyst onto which active components are doped or a material having the same surface characteristics as the catalyst is provided. In a method for adhering a catalyst of a material that is different from a matrix onto the matrix, a method for enhancement of adhesive force between the matrix and the catalyst comprises the step of forming the same material as a carrier of the catalyst or an adhesion layer having the same surface characteristics as the carrier of the catalyst between interfaces of a matrix and a carrier of a catalyst that is adhered onto a surface of a matrix. The matrix is a metal support formed from stainless steel, iron, aluminum, or alloys thereof. The matrix is an inorganic support selected from alumina, silica, titania, and zirconia.

CONSTITUTION: The equipment for adsorption is composed of an adsorption tower (11) packed with silica gel and activated carbon, adsorption recovery tower (12,13), a heat exchanger (14), a storage (15), and a vacuum pump. In the adsorption tower (11), the silica gel adsorbs the stronger adsorbable compounds such as pentene, hexane, or heptane and activated carbon does the weaker adsorbable compound such as methane, ethane, propane, butane, or pentane. The adsorbing process operates at 15-50 deg.C and 30-100 mmHg. The adsorption recovery tower (12,13) is carried out by the one process period of compression, adsorption, decompression, and pressing-cleaning. The recovery tower is operated at pressure of between 30 and 1000 mmHg by operation of vacuum pump. And, the heat exchanger (14) is operated at 1200-1800 mmHg.
