The catalyst technology is tested on equipment at the Ishimbay Specialized Chemical Catalyst Plant (Russia). The resulting samples of industrial catalyst are studied via XRF, H2-TPR, and DTG, and tested in the synthesis of hydrocarbons from CO and H2 at 250°C, a pressure of 2.0 MPa, and a gas hourly space velocity of 1000 h−1. It is shown that the bifunctional cobalt catalyst for producing low pour-point diesel fuel under industrial conditions allows properties of the catalyst obtained under laboratory conditions to be reproduced. The technology for obtaining the catalyst can be recommended for the production of industrial batches. It is found that changing the conditions of the catalyst’s heat treatment and the presence/absence of a peptizer and pore former do not appreciably reduce the productivity of C5+ hydrocarbons. The amount of the diesel fraction in C5+ products obtained on industrial catalyst samples remains at the same level as on the laboratory catalyst sample. At the same time, the low-temperature properties of diesel fuel obtained on all catalyst samples have similar values. The best low-temperature properties of diesel fuel are obtained on an industrial sample synthesized without a peptizer and a pore-forming component. The cloud point and the point of liquid loss are −16 and −24, respectively.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"16 3","pages":"254 - 262"},"PeriodicalIF":0.7,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the activity of homogeneous catalysts in the FA dehydrogenation reaction is higher than that of heterogeneous catalysts, the use of the latter makes it possible to simplify the technology and improve the environmental safety of hydrogen production from FA. An increase in the efficiency of heterogeneous FA dehydrogenation catalysts based on noble metals (Pd, Au, Ag) is achieved by developing novel methods for synthesizing monometallic, bimetallic, and trimetallic nanoparticles on various supports. The review compares the efficiency of various heterogeneous nanocatalysts in the FA dehydrogenation reaction and discusses various factors (metal nature, nanoperticle size and composition, support nature) that affect the activity and hydrogen selectivity of the catalysts. A significant increase in activity in the FA dehydrogenation reaction is achieved by intensifying the interaction of metal nanoparticles with the surface of a chemically modified support, which contributes to a decrease in the size of nanoparticles, an increase in the uniformity of their distribution on the support, and a change in the electronic state of the metal. Advances in the development of industrial heterogeneous catalysts for the production of pure hydrogen from FA will provide a significant contribution to the development of hydrogen power engineering.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"16 3","pages":"339 - 349"},"PeriodicalIF":0.7,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aluminas from Sasol molded in the form of extrudates (E) and spherical aluminas (S), in which the phase composition is presented by θ-Al2O3, δ-Al2O3, and α-Al2O3 alumina, have been used as supports. It has been shown that the phase composition of the support has a significant effect on the activity of supported Pd/WZ catalysts based on it. Upon transition from a set of θ- and δ-Al2O3 phases to the θ- and α-Al2O3 phase composition has led to an increase in the activity of the catalysts, as evidenced by a shift of 10–30°C in the temperature dependences of the heptane conversion to lower temperatures. The appearance of the α-Al2O3 phase is accompanied by a decrease in the specific surface area of the catalysts, which leads to an increase in the density of acid sites and, as a consequence, a change in activity. The Pd/WZ catalysts supported on S aluminas are characterized by a higher acidity (3.7–6.3 μmol/m2) as compared to the samples supported on E aluminas (2.8–3.6 µmol/m2). The high acidity of the Pd/WZ/S catalysts intensifies the heptane cracking side reactions to form gaseous C1–C4 hydrocarbons. In turn, the moderate acidity of the Pd/WZ/E catalysts contributes to a higher selectivity to heptane isomers (89.2–89.3% at a heptane conversion of 81.5–83.2%) as compared to the catalysts supported on S supports (isomerization selectivity of 84.9–85.6% at a heptane conversion of 80.4–81.4%).","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"16 2","pages":"133 - 140"},"PeriodicalIF":0.7,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141168009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sorption capacity achieved in 10 consecutive sorption–desorption cycles for 10 mol % NaNO3 is 4.5–5.5 mmol CO2/gsorb within 30 min of sorption at 50 vol % CO2 and temperatures of 300 and 350°C for the sorption and desorption stages, respectively.
