Steam Reforming Catalysts

Hydrocarbon First-stage Conversion Catalyst Z118Y

Hydrocarbon First-stage Conversion catalyst Z1118Y is suitable for the first conversion section of the synthesis ammonia, methanol or hydrogen production plant from different raw materials such as natural gas, coke oven gas, refinery gas, naphtha, and oilfield associated gas, to convert hydrocarbons and water into H₂, CO, CO^₂ Reaction.

It is also suitable for ammonia cracking hydrogen production plant.

Hydrocarbon First-stage Conversion Catalyst Z118Y is using a high-temperature sintered calcium aluminate carrier and a new impregnation process technology. It has:

● Special-shaped porous structure, low bed resistance;

● Special-shaped carrier plus rare earth, high strength, not easy to form carbon powder;

● Large effective surface area, good activity, thermal stability, and good low temperature activity.

Operating temperature: Inlet temperature 400-600°C; output temperature 650-850°C

Operating pressure: 0-5.0MPa

Water to carbon ratio: 2.5-5.0

Carbon space velocity: 600-2000h^-1

Sulfur content in feed gas: <0.2xl0~⁶

Heat resistance:

Activity at 800°C (dry gas CH₄) V %: W21 (Z118Y superior product)

Activity at 520°C (dry gas CH₄) V %: W64 (Z118Y-1 superior product)

1. It must be moisture-proof, drop-proof and anti-rolling during transportation.

2. Store in a ventilated and dry room. Products with damaged packaging and unclear labels cannot be used.

Hydrocarbon Second-stage Reforming Catalyst

Hydrocarbon Second-stage Reforming Catalyst further thoroughly transform the residual methane in the first reformed gas (generally, the outlet methane value is required to be less than 0.5%), and adjust the appropriate hydrogen-nitrogen ratio for synthesis.

Hydrocarbon Second-stage Reforming Catalyst is a new type two-stage conversion catalyst used magnesium aluminum spinel as a carrier. It has:

● Good thermal shock resistance;

● Strict impurity control;

● Better air distribution guidance.

Pressure: 0〜5.0 MPa

Temperature: 580〜1450 °C

Airspeed: 500~2000 h^-1

Water to carbon ratio (V/V): 0.5〜1.5

Heat resistance: <1450°C

1. It must be moisture-proof, drop-proof and anti-rolling during transportation.

2. Store in a ventilated and dry room. Products with damaged packaging and unclear labels cannot be used.

Steam Reforming Catalysts

Steam reforming catalysts mainly include a series of products such as Z111-6YQ, CN-16YQ, and CN-28YQ. Their manufacturing method and appearance are manufactured according to relevant Chinese patents obtained by our institute. According to the different components of the feed gas, select a specific model of primary conversion catalyst that is suitable. Our company's series of primary conversion catalysts are suitable for primary conversion furnaces using natural gas, oilfield gas, refinery gas, liquefied gas, and other raw materials.

1. Sizes and shapes can be provided according to user requirements.

2. The appearance color is usually gray or grayish black. In the actual production process, the product color may sometimes differ, but it does not affect its performance.

3. The actual loading density may vary due to factors such as the inner diameter of the furnace tube and the loading method.

(1) Inlet temperature of conversion tube: 420~650 ℃;

(2) Conversion tube outlet temperature: 650~950 ℃;

(3) Operating pressure: normal pressure~5.0 MPa;

(4) Dry gas airspeed at the inlet of the conversion tube: 500~3000h-1;

(5) Water carbon ratio at the inlet of the conversion tube: 2.5-7.0.

1. It must be moisture-proof, drop-proof and anti-rolling during transportation.

2. Store in a ventilated and dry room. Products with damaged packaging and unclear labels cannot be used.
