Z204 Conversion Catalyst for Ammonia Decomposition Furnace (I) Product Overview Nickel Catalyst (Ammonia Decomposition Z204 Catalyst) The Z204 conversion catalyst is a secondary conversion catalyst with nickel as the active component and alumina as the primary carrier. It is mainly suitable for secondary conversion furnaces in synthetic ammonia plants using gaseous hydrocarbons as raw materials, hydrogen production units, and ammonia decomposition units. Long-term usage has proven that this product offers stable performance, high activity, and excellent strength. (II) Physical and Chemical Properties 1.

Radial Crushing Strength per Particle (Average), N/particle ≥ 450 (III) Packaging and Storage The catalyst product is packaged in white plastic barrels that are moisture-proof and contamination-resistant, with a net weight of 50 kg per barrel. The exterior of the barrel is printed with clear markings including the name, model, specifications, weight (kg), and manufacturer. A product quality certificate is included inside the packaging barrel. During transportation, it should be protected from moisture, impact, and drops; rolling handling is prohibited. The product should be stored in a dry warehouse. Nickel Catalyst (Ammonia Decomposition Z204 Catalyst) Special catalyst for ammonia decomposition furnace liners, nickel content ≥14%, operating temperature from 780 to 850 degrees, decomposition rate up to 99.9%, residual ammonia content: 0.05%. After passing through the ammonia decomposition purification (cleaning) unit, the residual ammonia content can reach 5 ppm. Shipping packaging: 55-liter (net 50 kg) sealed plastic barrel packaging. Supplies ammonia decomposition hydrogen production equipment parts: Sichuan-produced 204 and 107 nickel catalysts for ammonia decomposition, nickel catalysts, nichrome (2080) heating wires, flat heating belts, YAQ-441 ammonia pressure reducing valves, imported American ammonia pressure reducing valves, Yangzhou Valve Factory shut-off valves, 5B ammonia decomposition-specific 106 iron catalysts, old-style ammonia decomposition-specific circuit boards, refractory bricks, purification-specific 5A molecular sieves, heating rods, thermocouples, temperature controllers, ammonia decomposition heat exchangers, water coolers, ammonia gas cylinders, ammonia-specific evaporators, storage tanks, ammonia decomposition furnace liners, etc. On-site renovation, maintenance, and servicing for ammonia decomposition hydrogen production. Ammonia decomposition uses Z204 nickel catalyst produced by Sichuan Chemical Research Institute, with nickel content greater than 14%. Higher decomposition rate, operating temperature from 800 to 850 degrees, decomposition rate up to 99.9%, residual ammonia content 0.1%. Specifically used as an ammonia decomposition catalyst in ammonia decomposition furnaces. After purification unit, residual ammonia content can reach 5 ppm. Performance is stable and reliable. Purification uses 5A molecular sieve to remove residual moisture and other impurities including residual ammonia. The purification unit adopts a dual adsorption tower process: one set dries the ammonia decomposition gas, while the other set, under heating conditions (typically 300-350°C), desorbs moisture and residual ammonia, thereby achieving regeneration. I. The AQ series ammonia decomposition units have been widely used domestically for over twenty years. Many users have reported encountering similar issues. In response to the demands of numerous ammonia decomposition users, our company has successfully provided nickel catalyst replacement services for hundreds of ammonia decomposition furnaces from Sujing, Hangyang, Tianyi, Feida, Shenlan, Changjiang, Jinpai, and others. Providing thorough, effective, and satisfactory service has always been our consistent service philosophy. Our professional technical service personnel can offer the following services: II. 1. Technical diagnosis and analysis of faults in ammonia decomposition hydrogen production units. III. 2. Provision of technical solutions. IV. 3. Supply of high-quality nickel catalyst and 5A desiccant. V. 4. Dispatch of technical personnel at any time for technical collaboration and guidance. VI. II. Regeneration and Reuse VII. 1. As mentioned earlier, when the catalyst's decomposition capacity declines due to improper operation, our company will arrange specialized technical personnel to provide services, conducting scientific and effective regeneration and reduction treatment for the degraded nickel catalyst and desiccant, especially for ammonia decomposition users.
