Abstract:
A reactor for hydrotreating, which comprises at least four catalyst layers packed respectively with hydrotreating catalysts, with said layers satisfying the relationship represented by the following formulae:Sn&lE;Sn+1 â€ƒâ€ƒ(1) 1.15Vn&gE;Vn+1 â€ƒâ€ƒ(2) wherein S represents the surface area per cubic meter of each hydrotreating catalyst layer; V represents the pore volume per cubic meter of each catalyst layer; and wherein n is a natural number representing the order of each catalyst layer, and with an amount of the catalyst packed into each catalyst layer being 3 to 70% by volume based on the total amount of the catalysts packed into the reactor.
