A fixed bed, radial flow reforming reactor having an inner catalyst zone between an inlet fluid zone and an outlet fluid zone. The catalyst zone is separated into two concentric, annular zones, a first annular zone having a first solid particle material having a first catalytic activity for reforming hydrocarbons into the catalyst zone, and, a second annular zone having a second solid particle material having a second catalytic activity for reforming hydrocarbons into the catalyst zone, wherein the second catalytic activity is different. One of the materials may be inert. A divider may be used to separate the two annular zones.

装置は、ユーザの端末とネットワークを介して接続され、ユーザのＲＦ装置における運転条件を提供する。装置は、端末からユーザ実績情報を取得し、基準実績情報とユーザ実績情報とを比較して基準運転関数を補正してユーザ運転関数を算出し、予定条件と流用条件とを取得し、予定条件と流用条件とユーザ運転関数から、ユーザ実績情報に含まれる触媒と予定条件と流用条件でユーザのＲＦ装置を運転した場合における、予定運転日数と最終到達温度のいずれかを算出して端末に出力する。

装置（２０）は、基準実績情報とユーザ実績情報とを比較して、基準運転関数を補正してユーザ運転関数を算出し、予定条件と制約条件と流用条件とユーザ運転関数に基づき、複数の触媒の種類について、予定条件と流用条件でユーザのＲＦ装置を運転した場合における、予定運転日数と最終到達温度のいずれか他方を算出し、算出された予定運転日数と最終到達温度のいずれか他方が制約条件を満たす触媒の種類の少なくとも一つを推奨触媒として端末（１０）に出力する。
