Palladium on Carbon Catalyst is a high-performance catalytic material designed for selective hydrogenation and oxidation reactions in fine chemical synthesis and pharmaceutical applications. Engineered with finely dispersed palladium nanoparticles on an activated carbon support, it ensures superior reaction kinetics, enhanced stability, and prolonged operational lifespan. This catalyst is widely used in organic synthesis, industrial refining, and environmental protection processes, delivering precise catalytic efficiency for large-scale applications.
Product Overview:
Palladium on carbon catalyst is a highly efficient catalyst primarily used in the hydrogenation of 4-CBA (4-carboxybenzaldehyde). This catalyst reduces 4-CBA to para-methylbenzoic acid (PMBA), which can then be easily separated to support the production of high-purity fiber-grade PTA (Purified Terephthalic Acid). The catalyst is widely applied in hydrogenation, reduction, and purification processes within petroleum refining, pharmaceutical, and other fine chemical industries. PDC-01 ensures a 98%+ conversion rate of 4-CBA, significantly improving the efficiency of PTA production.
Key Features:
- Efficient Hydrogenation:Specifically designed for the hydrogenation of 4-CBA, ensuring high conversion and efficient reduction.
- High Purity Products:Facilitates the production of high-purity fiber-grade PTA through catalytic reduction.
- Low Metal Impurities:Palladium content is precisely controlled to minimize interference from other metal impurities (such as iron, copper, and sulfur) in the reaction.
- Wide Applications:Suitable for hydrogenation and reduction processes in petroleum refining, pharmaceutical, and fine chemical industries.
Applications:
- PTA Production:Widely used in the hydrogenation of 4-CBA in PTA production, supporting efficient separation and crystallization of PTA.
- Petroleum Refining:Used in the hydrogenation and reduction refining of petroleum-based products.
- Pharmaceutical Industry:Applied in hydrogenation and reduction reactions in pharmaceutical synthesis.
- Fine Chemicals:Suitable for hydrogenation and reduction in various fine chemical processes.
