METHOD OF FILLING SOLID CATALYST

摘要

A method of filling a solid catalyst capable of reducing the pressure loss of a reaction tube in which the catalyst is filled, characterized in that cracked catalyst is removed by sorting the solid catalyst before the solid catalyst is filled in a reactor. For example, for the solid catalyst formed in a columnar or a cylindrical shape and having an outside diameter A larger than an axial length B, a sieve having sieve openings with a width of C meeting the requirement of A > C > B and a length equal to or larger than C is used for screening. For the solid catalyst having the outside diameter A of 1 to 0.5 times the axial length B, a sieve having sieve openings with a width of C meeting the requirement of A > C > 0.5B and a length equal to or larger than C is used for screening.
