A 400000 tons/year liquefied gas comprehensive utilization project of a petrochemical group in Liaoning Province, with mixed C4 as the raw material and main products including polypropylene, MTBE, light and heavy aromatics, and isobutane. The existing equipment includes 115000 tons/year OCU unit, 250000 tons/year gas fractionation unit, 30000 tons/year MTBE unit, and 60000 tons/year C4 aromatization (n-butane). The nitrogen purification unit requires no hydrogen or oxygen after purification, and the purification unit we cooperate with Perry Gas Company, a subsidiary of China Shipbuilding Heavy Industry 718 Research Institute, meets the purification requirements. The oxygen and hydrogen content of the finished gas is ≤ 0.5PPM.

The air separation argon purification unit of a certain steel group in Liaoning Province, due to its high oxygen content of 2-3%, releases heat of over 400 degrees, which is the limit temperature for ordinary alumina catalysts and is prone to sintering deactivation. Using our company's 506HT deoxygenation catalyst with titanium oxide as the carrier, due to the strong interaction between palladium and titanium, it can reach 650 ℃ without sintering, and its activity remains unchanged for seven years at such high working temperatures, The purification index meets the specified requirements and runs smoothly. Highly praised and trusted by users.

Although dehydrogenation in carbon dioxide gas is a common purification technology, dehydrogenation in carbon dioxide gas containing CO is still a difficult technical problem encountered in industry, and there are few reports in domestic literature. Due to the strong adsorption capacity of CO, when the feed gas passes through the Pd/Al2O3 catalyst bed, CO quickly adsorbs on the catalyst surface. Due to its strong inhibitory effect on catalyst activity, it leads to a significant decrease in catalyst activity. So if carbon dioxide contains CO gas, it cannot achieve the purpose and effect of deep dehydrogenation at room temperature.
