Prereforming A prereformer is an adiabatic fixed-bed reactor up-stream of the primary reformer. It allows increased flexibility in the choice of feedstock, increased lifetime of the steam reforming catalyst and tubes, and the option of increasing the overall plant capacity. Further-more it allows operation at lower steam/carbon ratios.

ReforMax 100 is a prereforming catalyst designed to handle the entire range of hydrocarbon feedstocks from natural gas up to and including LPGs and naphthas.

Steam Reforming Selection of the optimum catalyst depends on several factors, in-cluding furnace design, severity of service, and the type of hydro-carbon processed. Our recommended catalysts are shown in the table below.

Secondary Reforming The optimum catalyst for an air-fed secondary reformer depends on the design of the burner and the distance between burner tip and top catalyst layer. If hexagonal target bricks are not used, we recommend installation of a top layer of ReforMax 400 GG to serve as an active heat shield. This material is also ideal for a bottom active support layer where extreme short loadings are required and/or where high purity inert supports can be replaced with an active catalyst. ReforMax 410 LDP catalyst is used for the bulk of the reactor loading.

autothermal Reforming Oxygen-fed autothermal reformers require a mixed loading of catalysts, comprising an active heat shield and a reforming catalyst of excellent physical stability and thermoshock resistance. The standard catalyst loading is approx. 5 - 10% of ReforMax 420 on top of ReforMax 330 LDP catalyst.

Co Conversion Most ammonia plants convert CO to CO2 by high-tem-perature water-gas shift followed by low-temperature water-gas shift. For special process design, it can be advantageous to combine these two steps to form one isothermal or adiabatic step called medium tempera-ture CO conversion (MTS).

High-temperature CO Conversion The HTS catalyst ShiftMax 120 combines high activity with extremely good physical robustness. In addition, this catalyst is very effective in preventing Fischer- Tropsch by-product formation when operating at low steam to gas conditions.

Low-temperature CO ConversionThe LTS catalysts ShiftMax 230 and ShiftMax 240 are state-of-the-art products featuring excellent copper dispersion leading to unparalleled activity for water-gas shift. These catalysts feature higher CO conversion for longer life, enhanced resistance to poisons, and superior physical strength. The promoter in ShiftMax 240 suppresses the formation of methanol by more than 95% compared to standard LTS catalysts without decreasing activity.

Methanation Depending on the severity and product purity require-ments of the application, Clariant supplies two different types of methanation catalysts.

METH 134 consists of alumina supported NiO. For extremely low temperature applications (T < 170 °C) Clariant provides METH 150, which is comprised of ruthenium on an alumina support.

ammonia Synthesis AmoMax-10 is a wustite-based ammonia synthesis catalyst that features significantly higher activity than magnetite-based catalysts. This high activity level is also evident at low operating temperatures, allowing improved conversion at thermodynamically more favorable conditions. Wustite contains less oxygen than magnetite which means that reduction times can be significantly reduced. AmoMax-10 also features excellent long-term stability and is stronger than mag-netite-based catalysts. AmoMax-10 is available in oxidic and pre-reduced, stabilized forms.

Methanol Synthesis For the synthesis of methanol from carbon oxides and hydrogen, Clariant produces the MegaMax 800 cata-lyst, which is used in isothermal reactors (Lurgi-type) and all other plant designs, such as adiabatic quench type reactors. MegaMax 800 has extremely good low-temperature activity, which allows it to be operated at more thermodynamically favorable conditions. This catalyst also has excellent selectivity, even with high CO-content feed gas.

Methanol Reforming Hydrogen and carbon monoxide can be produced by means of steam reforming of methanol, which is per-formed with ReforMax M.

actiSorb Catalyst SeriesThe ActiSorb series of catalysts and adsorbents are used for the pu-rification of almost all hydrocarbon feedstocks. This purification is typically a combination of a reaction using a pre-treatment catalyst, i.e. hydrogenation, followed by adsorption with the ActiSorb adsor-bent. The following table gives a general overview of the different families of ActiSorb materials.

Sulphur RemovalSulphur in the form of organic compounds can be removed either as such or by hydrogenation to H2S followed by adsorption of the latter. The ActiSorb S 7 catalyst is recommended for the removal of H2S, mer-captans, disulphides and thiophenes in hydrocarbon feedstreams, ranging from naphtha to middle distillates. The achieved purity is less than 0.1 ppm wt. sulphur.

hydrodesulphurisation The standard catalysts for the hydrogenation of organic sulphur com-pounds in hydrocarbon feedstocks are the cobalt-molybdenum-type catalysts from the HDMax 200 series. These catalysts are used in both liquid and gas phase for all types of hydrocarbons, such as naph-tha, LPG, natural gas and off-gases. For the hydroge-nation of organic nitrogen compounds and/or olefin saturation, our nickel-molybdenum-based HDMax 301 catalyst is recommended.

h2S Removal The ActiSorb S series of ZnO-based adsorbents is used for the removal of sulphur components such as hydro gen sulphide, mer-captans and COS from hydrocarbon feedstreams. ActiSorb S 2 is the perfect solution when operating at high space velocities and elevated temperatures, while ActiSorb S 3 is recommended in applications with lower space velocities and higher inlet sulphur concentrations. The maximum bulk density catalyst ActiSorb S 1 is ideal in applica-tions where the feed contains high inlet sulphur concentrations, and where maximum sulphur pick-up per loaded unit volume is required.

Purification of natural gas containing low concentra-tions of total sulphur can also be performed by ActiSorb G 1, a promoted ZnO catalyst. Simultaneous hydrodesulphurisation and H2S pick-up is a feature unique to ActiSorb G 1. Even when saturated, the ActiSorb G 1 catalyst fully retains its hydrogenation capabilities.

CoS hydrolysis The ActiSorb 410 catalyst selectively promotes the simultaneous hydrolysis of COS and hydrogenation of CS2. HCN is also hydrolysed. The high selectivity of ActiSorb 410 means that process gases with very high CO concentrations can be treated.

The feed to the COS hydrolysis reactor usually contains nickel and iron carbonyls. These carbonyls decompose on the ActiSorb 410 catalyst into CO and the respective metals, leading to deactivation of the ActiSorb 410 cat-alyst. It is therefore necessary to install a guard reactor with ActiSorb 400 to selectively decompose any traces of metal carbonyls on the guard catalyst.

CoS and arsine Removal Refinery feeds and C3 streams from steam crackers often contain both COS and AsH3, and sometimes trace PH3. CuO catalysts such as ActiSorb 300 and ActiSorb 310 are currently used with great success, mainly to purify propylene. Absorption of poisons can be accomplished in either the gas or liquid phase. The product purity achieved is normally below the detectable limit. As a result, the selective hydrogenation catalyst installed downstream is perfectly protected and can pursue its basic activity and selectivity.

The consumption of polymerisation catalysts is drastically reduced with a poison guard. Feed polishing prior to polymerisation is therefore extremely valuable for downstream operations.
