Hydrogenation catalyst

Classification of hydrogenation catalysts: H-1 organic sulfur hydrogenation conversion catalyst. The H-1 hydrogenation conversion catalyst uses modified γ-Al2O3 as a carrier and Co-Mo and similar elements as active components. It features a large specific surface area, large pore volume, uniform distribution of active components, high hydrogenation activity and organic sulfur hydrolysis activity, as well as good activity stability. It has a high conversion capacity for complex organic sulfides. It can be used for the hydrogenation conversion of organic sulfides in gaseous and liquid hydrocarbons such as natural gas, oil field gas, liquefied petroleum gas, and naphtha. Suitable for large and medium-sized ammonia plants, methanol plants, hydrogen production facilities, and other petrochemical enterprises. This catalyst can reduce the organic sulfur content in the feed hydrocarbon to below 0.1 ppm. H-2 coke oven gas hydrogenation conversion catalyst The H-2 coke oven gas hydrogenation conversion catalyst is a new type of organic sulfur hydrogenation conversion catalyst. Due to a special preparation process, the catalyst’s activity is about twice higher than that of similar products. This catalyst is primarily used in the hydroconversion process to remove organic sulfur from coke oven gas, where the CO content is below 10% and the olefin content is around 5%. Under conditions of an air velocity of 500–1000 h-1, a reaction temperature of 380–450°C, and a pressure of 1.0–2.0 Mpa (gauge pressure), the total conversion rate of organic sulfur in coke oven gas containing 100–250 mg/Nm3 of organic sulfur can reach over 95%. H-3 hydrogenation desulfurization and dearsenification catalyst: The H-3 catalyst is a new type of catalyst for hydrogenation desulfurization and dearsenification. This catalyst exhibits high hydrogenation conversion capabilities for organic sulfides, olefins, oxygen, and organic basic nitrogen in the feed gas, as well as strong arsenic removal capacity. It is suitable for arsenic removal and hydrodesulfurization of feed gas (or oil) in large ammonia synthesis plants, refineries, etc. H-4 coking dry gas hydrogenation catalyst: The H-4 catalyst exhibits a high capacity for hydrogenating organic sulfides and olefins present in the feed gas. It is suitable for the hydrogenation of coker dry gas with an olefin content of <8%, and it is also applicable to the hydrogenation conversion of feedstocks such as petroleum fractions, refinery gas, natural gas, field gas, and water gas. It is particularly suitable for hydrogen production plants that use coker dry gas as raw material, and performs well in such applications. H-5 water-gas hydrogenation catalyst: The H-5 catalyst can be used in the hydrogenation of gases such as water gas and syngas, and it exhibits a high capacity for hydrogenating organic sulfides, olefins, and oxygen present in these gases. This catalyst is also suitable for petroleum fractions. The hydrogenation conversion process of feed gases such as natural gas and oilfield gas. It exhibits strong resistance to coking against up to 37% CO in syngas or water gas, or 10% CO2. H-6 hydrogenation refining catalyst: The H-6 hydrogenation catalyst uses modified γ-Al2O3 as a carrier, with tungsten, molybdenum, and nickel as active components. It features high pore volume, large specific surface area, high strength, and good activity for hydrogenation desulfurization and denitration. It is suitable for the hydrorefining of liquefied gas, gasoline, heavy gasoline, naphtha, aromatics, etc., to remove impurities such as sulfur, nitrogen, and gums from the oils, improve the quality of these oils, and produce high-quality gasoline and diesel with sulfur content that meets international fuel standards. The H-9 selective hydrogenation catalyst is a precious metal-based selective hydrogenation catalyst used to selectively hydrogenate and saturate alkynes and dienes in ethylene at low temperatures, without affecting ethylene itself. It features high activity, good selectivity, and strong stability, as well as excellent resistance to sulfur poisoning and polymerization ； The process conditions of the device are mild, making it easy to operate.

The above are Zibo Xunda’s products, namely the technology of Qilu Institute.

The answer on the second floor can be found anywhere online; it doesn’t seem to relate to the question at all, does it? I’ve searched for a long time but still can’t find the exact answer. Could some teacher give me some guidance? !
