Abstract: The present invention relates to a polyester sound absorption material having improved moldability and decreased weight and a method of manufacturing a molded product using the same, and more particularly to a polyester sound absorption material, which is capable of integrally molding a skin member and a sound absorption material using a felt including a polyester base fiber, a low-melting-point polyester adhesive fiber and a polyester hollow fiber, without the need to attach an additional sound absorption pad onto a skin member.

Abstract: Disclosed is a Co/Al2O3/SiC catalyst for Fischer-Tropsch synthesis exhibiting superior heat transfer and mass transport effects, wherein an Al2O3/SiC support in which alumina is coated on silicon carbide (SiC) with superior thermal conductivity is used and cobalt (Co) is supported thereon as an active component to provide a bimodal pore size distribution, and a method for preparing same. Use of the Al2O3/SiC support improves cobalt dispersion and enhances cobalt-support interaction, thereby inhibiting generation of cokes (carbon filaments). As a result, catalyst stability is improved and conversion of syngas (carbon monoxide and hydrogen) can be improved.
