Pd-Al Selective Hydrogenation Catalyst

Product Overview

The Pd-Al selective hydrogenation catalyst uses alumina as the support, with palladium as the primary active component, supplemented by special additives. It is specifically designed for the selective hydrogenation of benzene fractions, toluene, and xylene. The catalyst offers high catalytic activity, excellent selectivity, outstanding stability, and excellent compressive strength. It effectively removes olefins in the hydrogenation reactions of benzene, toluene, xylene, and other aromatics, while minimizing the loss of aromatics. The catalyst meets the bromine index requirements for benzene, toluene, xylene, and raffinate oils. This product has been widely used in numerous industrial units and complies with increasingly stringent environmental protection standards.

Key Features

• High Catalytic Activity: The catalyst rapidly activates reactions during hydrogenation, ensuring efficient conversion.
• Good Selectivity: Effectively removes olefin impurities while maintaining the aromatic content, meeting quality standards for benzene, toluene, and xylene production.
• Strong Stability: It has a long service life and excellent stability during extended operation, making it suitable for various hydrogenation conditions of benzene fractions.
• High Compressive Strength: The catalyst exhibits strong compressive strength, allowing it to withstand high-load processing conditions.
• Wide Application Range: Suitable for hydrogenation of reformate benzene fractions, semi-regenerated reformate oils, and full fractions of continuous reformate oils.

Applications

• Reformate Benzene Hydrogenation: Used to remove olefins from reformate benzene fractions, particularly in the hydrogenation of olefins in benzene, toluene, and xylene, with minimal loss of aromatics.
• BTX Fraction Processing: Widely used in the selective hydrogenation of BTX fractions (benzene, toluene, xylene) to produce products that meet bromine index requirements.
• Environmental Protection: This catalyst helps produce benzene, toluene, xylene, and raffinate oils that meet environmental protection regulations, fulfilling increasingly stringent environmental standards.
