This book was released on 2010 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of supported palladium catalysts that had been modified with triphenyl phosphine, diphenyl sulfide and triphenyl amine was compared to unmodified Pd/TiO2 catalysts. It was found that the selectivity was superior to the unmodified catalysts with or without the use of carbon monoxide as a modifier. Ethylene selectivities in excess of 70 % at conversion levels greater than 80% were observed on the modified catalysts under conditions of excess hydrogen which compares extremely well with other catalysts found in the literature. The modifier was found to significantly reduce the number of high energy sites on the surface on the palladium, thereby significantly hindering ethylene hydrogenation but not affecting acetylene hydrogenation. The simple preparation of these catalysts together with the simplicity added by not having to use carbon monoxide or limited hydrogen promises a viable alternative strategy for commercial catalysis.

This book was released on 2017-01-05 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis offers novel methods for catalyst and process design for the selective hydrogenation of acetylene and 1,3-butadiene. The author predicts the properties of supported Pd–Ni bimetallic catalysts using density functional theory (DFT) calculations and temperature-programmed desorption (TPD). The excellent correlation between model surfaces and supported catalysts demonstrates the feasibility of designing effective bimetallic catalysts for selective hydrogenation reactions. The author also proposes a method for designing non-precious metal catalysts to replace precious metals. She modifies the process of selective hydrogenation of acetylene by coupling the selective adsorption to the selective hydrogenation in the liquid phase, as a result of which the ethylene selectivity is greatly improved and heat transfer is greatly enhanced. Lastly, by analyzing the mechanism of liquid-phase hydrogenation, the author proposes a multi-stage slurry bed reactor for industrial applications.“/p>

Available in PDF, EPUB and Kindle. Book excerpt: With contributions from experts in supported metal catalysis, from both the industry and academia, this book presents the latest developments in characterization and application of supported metals in heterogeneous catalysis. In addition to a thorough and updated coverage of the traditional aspects of heterogeneous catalysis such as preparation, characterization and use in well-established technologies such as Naphtha reforming, the book also includes emerging areas where supported metal catalysis will make significant contributions in future developments, such as fuel cells and fine chemicals synthesis. The second edition of Supported Metals in Catalysis comes complete with new and updated chapters containing important summaries of research in a rapidly evolving field. Very few other books deal with this highly pertinent subject matter, and as such, it is a must-have for anyone working in the field of heterogeneous catalysis.

Download or read book Heterogeneous Catalysts for Petrochemical Synthesis and Oil Refining written by Eduard Karakhanov and published by Mdpi AG. This book was released on 2021-10-07 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heterogeneous catalysis is among the major solutions for cost-effective and sustainable industrial application and processing. The design and development of highly efficient and stable heterogeneous catalysts represent an emergent frontier for overcoming energy and environmental challenges. Many industrial petrochemical and oil refining processes are faced with new challenges that can be solved using heterogeneous catalysts. This book covers the most recent progress and advances in the field of heterogeneous catalysts based on mesoporous composites with embedded halloysite nanotubes covered with ruthenium nanoparticles for exhaustive aromatics hydrogenation, generated in situ and supported on zeolites' transition metal sulfides for the hydrocracking of the pyrolysis fuel oil and n-alkanes isomerization. This book also includes investigations of novel rhodium systems supported on FeCrAl composite for the coupling of pre-reforming and partial oxidation to liquefied petroleum gas processing into syngas. We have collected works devoted to the palladium catalysts based on porous aromatic frameworks and alumina for the hydrogenation of unsaturated compounds (alkynes, alkenes and dienes) and for the selective removal of acetylene from ethane-ethylene fractions.

Download or read book Liquid-phase Selective Hydrogenation of Phenylacetylene on Palladium Nanoparticles Supported on Mesoporous Silica written by and published by . This book was released on 2009 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of palladium catalysts with ca. 1 wt% palladium supported on mesoporous silica with different pore sizes (MCM-41, SBA-15, and MCF) were prepared by deposition of colloidal Pd nanoparticles (Pd/X_col) and Pd(II)acetate solution (Pd/X_imp). MCM-41 and SBA-15 showed the XRD characteristic peaks indicating highly ordered hexagonal pore structure while MCF consisted of spherical cell and frame structure with average pore size of 2.7, 3.9, and 7.8 nm, respectively. Sizes of the colloidal Pd nanoparticles were about 2.3 nm. The supports pore structure did not affect the Pd particle size of Pd/X_col catalysts. For the Pd/X_imp, the Pd particle size was increased with increasing pore diameter of the supports. However, the largest Pd particle size was obtained on Pd/SBA-15_imp since the Pd particles were formed in a long cylindrical shape similar to SBA-15. The Pd/SBA-15_col exhibited the best catalyst performance in the liquid-phase selective hydrogenation of phenylacetylene under mild conditions (40 degress celsius, H2 pressure = 1-5 bar, 30 min). The appropriated pore structure and pore size of SBA-15 could provide a better encapsulation of Pd particles so that high styrene selectivity was attained at complete conversion of phenylacetylene. All the Pd/X_col catalysts exhibited no change in the catalyst activities/selectivity during the recyclability test for four cycles while the Pd/X_imp showed an increase of catalyst activity and lower styrene selectivity in some cases.
