Catalysts for the hydrogenation of light hydrocarbons
Applications:
Hydrogenation of light hydrocarbons
Process Introduction
Compared with the traditional Pd/Al2O3 catalyst, HPC catalysts have large specific surface area (BET>300 m2/g), high activity and selectivity, strong stability and high toxic and wear resistance. The core technology of HP series catalysts are using molecular film technology (RSM) and layer-protective technology (CDP), which improved the selectivity and activity. In addition, HPC catalysts are pre-activated before delivery, and could be used after packing.

Catalyst and process package for selective hydrogenation of acetylene and diolefin from light hydrocarbons (C3, C4, C5, light gasoline), mainly used in the following process：
- Selective hydrogenation of 1,3-butadiene in C4 mixture to 1-butene, which is used as the monomer for the production of LLDPE and HDPE.
- Selective hydrogenation of acetylene and 1,3-butadiene in C4 or C5 mixture to ethylene and propylene, which is used for the OCU instruments.
- Selective hydrogenation of acetylene and 1,3-butadiene in C4 or C5 mixture to ethylene and propylene, which is used for the OCC instruments.
- Selective hydrogenation of 1-butyne and 1,3-butadiene in C4 mixture to 1-butene, which is used in the cracker instruments and for the synthesis of methyl ethyl ketone.
- Selective hydrogenation of acetylene and 1,3-butadiene in C5, C6 and gasoline Fraction, for extending the etherification catalyst life and upgrading the product quantity.
- Selective hydrogenation of acetylene to ethylene (cracker instrument), which is used for the production of HDPE、LLDPE、FDPE
- Selective hydrogenation of acetylene to ethylene (cracker instrument), which is used for the production of HDPE、LLDPE、FDPE
Deep hydrogenation of light hydrocarbons (C3, C4, C5, light gasoline) catalysts and process packages, mainly used in the following processes:
- Deep hydrogenation of olefins in C3mixture from PDH and cracking instruments.
- Deep hydrogenation of C4 mixture for the production of n-butane and iso-butane, cracking of ethylene, dehydrogenation of iso-butane.
- Deep hydrogenation of C5 mixture.
The catalyst has been used in place of foreign catalysts in many hydrogenation instruments in china and showed a much higher activity and selectivity than that produced by competitor such as Axens, Evoni and BASF.
