Title: In situ evolved gas analysis assisted thermogravimetric (TG-FTIR and TG/DTA–MS) studies on non-activated copper benzene-1,3,5-tricarboxylate

Abstract

The results of a complete thermogravimetric study of copper benzene-1,3,5-tricarboxylate (Cu-BTC or HKUST-1) are reported here together with mass spectrometry (MS) and Fourier transform infrared spectroscopy (FTIR) analyses of the evolved gases up to 800 °C. Oxidative and inert conditions were applied to reveal the stoichiometry of the as-received synthesis product. In spite of using a water-ethanol mixture during the synthesis and the filtration, only water is retained in the pores. It is proposed that the thermolytic release of ethanol in the temperature range 150–250 °C originates from ethanol-benzene-1,3,5-tricarboxylate (BTC) esters situated on the surface of the HKUST-1 crystal, and which limit the size of the developing crystals during the synthesis.

  • The direct conversion of methane to aromatics such as benzene and naphthalene has been studied on a series of Mo-supported catalysts using HZSM-5, FSM-16, mordenite, USY, SiO{sub 2}, and Al{sub 2}O{sub 3} as the supporting materials. Among all the supports used, the HZSM-5-supported Mo catalysts exhibit the highest yield of aromatic products, achieving over 70% total selectivity of the hydrocarbons on a carbon basis at 5--12% methane conversion of 973 K and 1 atm. By contrast, less than 20% of the converted methane is transformed to hydrocarbon products on the other Mo-supported catalysts, which are drastically deactivated, owing to seriousmore » coke formation. The XANES/EXAFS and TG/DTA/mass studies reveal that the zeolite-supported Mo oxide is endothermally converted with methane around 955 K to molybdenum carbide (Mo{sub 2}C) cluster (Mo-C, C.N. = 1, R = 2.09 {angstrom}; Mo-Mo, C.N. = 2.3--3.5; R = 2.98 {angstrom}), which initiates the methane aromatization yielding benzene and naphthalene at 873--1023 K. Although both Mo{sub 2}C and HZSM-5 support alone have a very low activity for the reaction, physically mixed hybrid catalysts consisting of 3 wt% Mo/SiO{sub 2} + HZSM-5 and Mo{sub 2}C + HZSM-5 exhibited a remarkable promotion to enhance the yields of benzene and naphthalene over 100--300 times more than either component alone. The bifunctional catalysis of Mo/HZSM for methane conversion towards aromatics is discussed by analogy with the promotion mechanism on the Pt/Al{sub 2}O{sub 3} catalyst for the dehydro-aromatization of alkanes.« less
  • This paper attempts to relate oxygen-containing gases H{sub 2}O, CO{sub 2}, and CO evolved during pyrolysis of the Argonne premium coals to oxygen-containing functional groups as a function of rank. Our approach to functional group analysis of oxygen-containing species in coal has been to use a pyrolysis technique, thermogravimetric Fourier transform infrared spectroscopy (TG-FTIR), involving thermogravimetric analysis with the measurement of the gaseous decomposition products via IR detection. Under suitable heating conditions, TG-FTIR pyrolysis of a coal sample in a stream of inert gas has been shown to expel quantitatively all of the organic oxygen in the form of H{submore » 2}O, CO{sub 2}, and CO, and consequently, this technique can be effectively applied for determining the total oxygen content. Focusing on the Argonne premium coals, which cover a wide range in rank between lignite (Ro = 0.25) and low-volatile bituminous (Ro = 1.68), TG-FTIR provided complex pyrolysis profiles of oxygen-containing gases, which yield information on the sources of the different peaks observed in coal as a function of rank from a chemical-structure standpoint. Deconvolution of the complex profiles was performed to assign peaks to the different sources of oxygen-containing gases. Model polymers containing various oxygen functional groups in aliphatic and/or aromatic molecular environments were also pyrolyzed by TG-FTIR in an attempt to assign peaks in the gas evolution profiles of the Argonne premium coals. Although complex evolution profiles were observed for the three oxygen-containing gas species H{sub 2}O, CO{sub 2}, and CO in the Argonne premium coals, the strength of the TG-FTIR technique in revealing both similarities and differences in profiles depending upon the coal rank was evident. 19 refs., 6 figs., 9 tabs.« less
  • The interaction of CO with YBa[sub 2]Cu[sub 3]O[sub x] (x [approximately] 7) has been studied using differential thermal analysis (DTA)/thermogravimetry (TG), Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS). The interaction at temperatures between 400 and 800 K proceeds as CO + O(lattice) = CO[sub 2], as shown by the evolved gas analysis and DTA/TG calorimetric measurement. At 800-1200 K a large CO uptake is observed, resulting in the formation of BACO[sub 3], which is characterized by FTIR, and the reduction of Cu(II) and Y(III), as observed by XPS. An apparent activation energy of 16 kcal/mol and amore » heat of reaction of 60 kcal/mol are estimated for this high-temperature reaction from the DTA/TG studies. These results are compared with those obtained for YBa[sub 2]Cu[sub 3]O[sub y] (y [approximately] 6) and the composite compounds, CuO, Y[sub 2]O[sub 3], and BaCO[sub 3]. A detailed mechanism which may explain the higher catalytic activity on YBa[sub 2]Cu[sub 3]O[sub x] than on CuO[sub 3] is suggested.« less
  • The contribution of a redox mechanism involving lattice oxygen in the catalytic combustion of methane over PdO/ZrO{sub 2} catalysts, prepared from amorphous Pd-Zr alloys, has been studied by means of gas pulse methods, including a novel technique `pulse thermal analysis`, and using labeled catalysts containing Pd{sup 18}O. Special emphasis was devoted to the influence of the isotope exchange (scrambling) of reactants and products, especially O{sub 2} and CO{sub 2}, with the catalyst on the quantity of {sup 18}O-containing reaction products. Substantial amounts of H{sub 2}{sup 18}O and C{sup 18}O{sup 16}O were detected during pulses of a reactant mixture consisting ofmore » methane and {sup 16}O{sub 2} in a ratio 1:4 at 300 and 500{degree}C. The effect of the oxygen exchange of molecular oxygen with the solid phase proved to be negligible due to its low extent. At 300{degree}C, at least 20% of the CO{sub 2} formed originated from the redox mechanism involving lattice oxygen. At 500{degree}C, oxygen exchange of CO{sub 2} with the catalyst became predominant and precluded determining reliably the proportion of CO{sub 2} formed by the redox process. The results indicate that a substantial part of methane is oxidized via a redox process. Consequently, this reaction has to be taken into account when interpreting the catalytic behavior of palladium-based catalysts and explaining the structure-activity relations previously observed. 66 refs., 9 figs., 2 tabs.« less
  • The first results of thermogravimetric Fourier transform infrared analysis (TF-FTIR), as applied to petroleum source rocks, are reported. Sample preparation and running time, roughly equivalent to those used for Rock Eval source rock pyrolysis analyses, are described. Initial results show that the TG-FTIR technique provides considerable additional geochemical information including the following: (a) Simultaneous T/sub max/ values for thermal evolution of a number of constituents in addition to hydrocarbons and carbon dioxide-including methane, ethylene, carbon monoxide, ammonia, hydrogen cyanide, sulfur dioxide, and COS are obtained. T/sub max/ values of several of these-including methane, ethylene, and ammonia-show progressive increases with maturationmore » state. For one Alaskan North Slope well (Seabee), these T/sub max/ values show an excellent correlation with vitrinite reflectance. (b) Data required for calculation of material balances of organic and inorganic sedimentary carbon, nitrogen, and sulfur are obtained. (c) Data for classification of sedimentary organic matter into kerogen types I, II, and III (using either plots of organic H/C versus O/C or H/C versus organic carbon ratios) as well as data for classification according to depositional environment (using thermal evolution patterns of ammonia, HCN, SO/sub 2/, and COS and possibly CO/sub 2/) are obtained.« less
