◼TECHNICAL  INDEX

RSR-101/102 series light hydrocarbon steam reforming hydrogen production catalyst has six major characteristics of "one high, three strong, two small", namely

(1) high conversion activity, can achieve near thermodynamic equilibrium conversion, the equilibrium temperature distance is less than 5℃.

(2) strong C2+ hydrocarbon cracking ability, can prevent heavy hydrocarbons from penetrating and causing carbon deposition.

(3) strong anti-carbon deposition performance, can achieve low water-carbon ratio long- term stable operation.

(4) strong raw material adaptability, suitable for industrial hydrogen production equipment with natural gas, refinery dry gas and liquefied gas as raw materials.

(5) low corrosion to equipment, avoid the problem of K loss of traditional hydrogen production catalyst, and prevent equipment corrosion.

(6) small bed pressure drop, can reduce the compression system load and reduce compression power consumption.

Under the same device load conditions, compared with the reference agent, the catalyst bed pressure is reduced by 8~10%, the outlet temperature is 5~20℃ lower, and theoperating water-carbon ratio is 0.2~0.5 units lower.

◼What is the core innovation of the RSR-101/102 catalyst? What are the main differences from traditional catalysts?

Its core innovation lies in achieving exceptional performance through comprehensive optimization of its formulation, preparation method, and geometric structure, achieving the hallmarks of "one high, three strong, and two small." Compared to traditional catalysts, its most significant difference lies in its ability to operate stably at lower water-to-carbon ratios (3.0-3.2) and its excellent resistance to carbon deposition, fundamentally addressing the carbon deposition and equipment corrosion issues caused by heavy hydrocarbon cracking or potassium loss. Furthermore, this catalyst exhibits a lower bed pressure drop, reducing system energy consumption by approximately 10%.

◼What specific economic benefits can “stable operation with low water-carbon ratio” bring to enterprises?

Reducing the water-to-carbon ratio is key to energy conservation and consumption reduction in hydrogen production plants. A reduction of 0.2-0.5 units in the water-to-carbon ratio significantly reduces the fuel gas required to produce the same amount of steam. Industrial application data shows that using RSR-101/102 catalysts can directly reduce the overall energy consumption of hydrogen production plants by 10%, significantly reducing fuel costs and CO₂ emissions. This yields significant economic and environmental benefits.

◼How adaptable is the catalyst to the raw materials? Can it process low-quality raw materials?

This catalyst boasts robust feedstock adaptability and is specifically designed for processing complex feedstocks. It is highly effective for natural gas and liquefied petroleum gas (LPG), and is particularly adept at processing refinery dry gas with complex composition and high levels of C2+ heavy hydrocarbons. Its enhanced C2+ hydrocarbon cracking capacity and carbon deposition resistance effectively prevent heavy hydrocarbon penetration, ensuring stable unit operation despite feedstock fluctuations.

◼What is the significance of “balanced temperature difference less than 5°C” mentioned in the product introduction?

The "equilibrium temperature difference" is a key indicator of catalyst activity. It refers to the difference between the actual reaction temperature and the theoretical thermodynamic equilibrium temperature. The smaller the difference, the higher the catalyst activity. The RSR-101/102 can control this temperature difference within 5°C, indicating that its conversion efficiency is close to the theoretical limit, resulting in more complete hydrocarbon conversion, higher hydrogen yield, and extremely optimal raw material utilization.

◼What issues should be paid attention to when replacing your company's catalyst in industrial equipment?

The replacement process is typically quick and efficient. RSR-102 (lower stage catalyst) offers enhanced cracking and carbon deposition resistance, while RSR-101 (upper stage catalyst) boasts high activity and stability. The combination of these two catalysts provides low bed pressure drop, eliminating any special requirements for existing reactor internals or downstream compression system loads. We can provide detailed technical solutions and loading instructions to ensure a smooth and efficient catalyst changeover.
