1. Excellent hydrocarbon steam reforming activity, anti-carbon performance and structure stability.
2. The catalyst shape of 4-hole cylinder with dome provides it with large external geometric surface area, higher porosity, lower pressure drop, and better gas flow distribution etc..
3. Versatile catalyst options for various hydrocarbon feedstock used alone or combination. Switching or dosage adjustment of feeds does not affect the normal use of catalyst.
1.Used in steam reforming process of hydrocarbons to produce hydrogen, ammonia synthesis gas, methanol synthesis gas, oxo- synthesis gas, carb on monoxide etc..
2.Suitable for a wide range of feedstock, such as naphtha with FBP less than 180℃, light hydrocarbons, LPOG, refinery off- gas, natural gas etc., which can be used alone or in combination.
3.Suitable for various types of tabular reformers with top-fired, fired, side -bottom -fired firebox or other configurations such as heatexchanger etc., AMC-Z-417 should beloaded in the upper section of the reformertubes in combination with AMC-Z-418 loaded in the lowder part.
4.Excellent reducibility: through self- circulation reduction, natural gas feedstock can be directly introduced into the reformer without extra activation in advance, and pre- activation is needed only when heavy hydrocarbons are used as feedstock.
5.Excellent anti-poisoning and regeneration properties: can be self- renewal by optimizing operation conditions when sightly poisoned by sulfur or chlorine, while in-situ regeneration can be performed when poisoned seriously.
6.Suitable for steam reforming process with or without pre- reformer, even for pre- reformer switching on/off cases.
