Catalyst carrier, which is supported on carbon with a macroporous for purifying aromatic acid

摘要

Regards the catalyst mixture which contains the catalyst carrier which the active carbonizing character material where one aspect of this invention has the pore structure which especially is stipulated and was pushed out is contained was pushed out. For example, this as for the active carbonizing character material which was pushed out, it is possible to possess the pore which is obtained in the pore where at least approximately 40% all the Hg porosity has the diameter above approximately 200 . As another method, this as for the active carbonizing character material which was pushed out, at least also approximately 40 and many have the pore diameter of approximately 100 , at least the pore of 1st group porosity of approximately 0.15cc/g, and at least also approximately 5,000 and many have the pore diameter of approximately 20,000 , include the pore of 2nd group porosity of approximately 0.3cc/g are possible to become at least and.
