Publication number: 20240139669Abstract: A method for preparing hydrogen from ammonia by using pressure swing adsorption (PSA) is provided. The method for preparing hydrogen from ammonia, of the present invention, comprises the steps of: generating hydrogen and nitrogen from ammonia gas through a high-temperature reaction by using a catalyst; performing purification by selectively adsorbing unreacted ammonia gas from a gas containing unreacted ammonia and low-purity hydrogen and nitrogen, which are supplied through the high-temperature reaction and cooled; and performing purification by separating high-purity hydrogen from the gas consisting of low-purity hydrogen and nitrogen, wherein purification is carried out by using a carbon molecular sieve (CMS) adsorbent so as to desorb the unreacted ammonia gas through PSA.Type: ApplicationFiled: November 10, 2022Publication date: May 2, 2024Applicants: POSCO CO., LTD, RESEARCH INSTITUTE OF INDUSTRIAL SCIENCE & TECHNOLOGYInventors: Chi-Kyu Ahn, Chang-Houn Rhee, Gook-Hee Kim, Man-Su Lee, Hai-Woong Park, Beom-Sik Kim, Seong-Min Son

Patent number: 9895337Abstract: The invention relates to pharmaceutical compositions, as well as health functional food compositions and quasi-drug compositions, for preventing, treating, or improving rheumatoid arthritis, comprising a monoacetyldiacylglycerol compound as an active ingredient. The monoacetyldiacylglycerol of the invention is effective in inhibiting the phosphorylation of STAT-3 known to be a therapeutic target for rheumatoid arthritis. As the monoacetyldiacylglycerol is an effective therapeutic agent without toxicity, the monoacetyldiacylglycerol can overcome the side effects of the medicines currently used in the treatment of rheumatoid arthritis. Thus, the monoacetyldiacylglycerol can be used for preventing, treating or improving rheumatoid arthritis.Type: GrantFiled: February 19, 2016Date of Patent: February 20, 2018Assignees: Enzychem Lifesciences Corporation, Korea Research Institute of Bioscience and BiotechnologyInventors: Jae Wha Kim, Sei Ryang Oh, Kyung Seop Ahn, Ho Bum Kang, Beom Su Park, Tae Suk Lee, Jong Koo Kang, Young Sik Jung, Ki-Young Sohn
