APPLICATION OF DUAL-FUNCTION CATALYST IN HYDROTREATING COKING RICH GAS FOR HYDROGEN PRODUCTION

A countercurrent isothermal-adiabatic hydrotreating process was developed by PetroChina Liaohe Petrochemical Company and Zhejiang Engineering Design Institute in order to use coking rich gas as feedstock to produce hydrogen. The coking rich gas was treated with dual-function JT-1G/JT-4 hydrotreating catalysts in this process. Results from commercial running showed that the JT-1G/JT-4 hydrotreating catalyst not only effectively saturated the olefins but also converted the organic sulfur containing compounds. The catalysts showed good activity at low temperature with high adaptability to the change of olefin content in the feed. Even the olefin content of the coking rich gas was as high as 13%-16%(vol), the treated gas had no presence of olefin. Furthermore, the organic sulfur was fully converted to inorganic sulfur which can be easily removed. Such hydrotreated coking rich gas met the requirements of feedstock for hydrogen production and the cost of hydrogen could be lowered.
