  Phase ratios in the K2O-V2O4-SO3 system at high sulfur trioxide concentrations

  摘要：

  Phase ratios in the three-component oxide system K2O-V2O4-SO3 in the region of the sulfur trioxide concentrations corresponding to its concentrations in the active component of vanadium catalysts for SO2 to SO3 conversion have been studied using powder X-ray diffraction, IR spectroscopy, microscopy, and chemical analysis. Four individual compounds (K2VO(SO4)(2), K-2(VO)(2)(SO4)(3), K2VO(SO4)(2)S2O7, and K-2(VO)(2)(SO4)(2)S2O7) and K-2(VO)(2)(SO4)(2)S2O7 and VOSO4-base solid solutions of composition K-2(VO)(2+x) (SO4)(2+x) S2O7 (0 <= x <= 1.5) were found in the system. K2VO(SO4)S2O7 and K-2(VO)(2)(SO4)(2)S2O7 lose their sulfur trioxide when heated above 350 degrees C under an inert atmosphere, and convert to K2VO(SO4)(2) and K-2(VO)(2)(SO4)(3), respectively. This implies that K2VO(SO4)(2)S2O7 and K-2(VO)(2)(SO4)(2)S2O7, as well as K-2(VO)(2+x) (SO4)(2+x) S2O7 solid solution, cannot exist in the active component of real industrial catalysts.

  Powder X-ray diffraction and microscopy have been used to study phase ratios of the M2O-V2O5-SO3 (M = Rb, Cs) systems, which model the active component of rubidium-vanadium and cesium-vanadium catalysts for sulfuric acid production at high sulfur dioxide conversions. We have stated that each system forms four compounds: M3VO2(SO4)(2), MVO2SO4, M4V2O3(SO4)(4), and MVO(SO4)(2). The thermal properties of these compounds and their interaction with water vapor saturated at room temperature have been studied. The unit cell parameters have been determined for the compounds MVO2SO4 (M = K, Rb), MVO(SO4)(2), and M[VO2(SO4)(H2O)(2)] center dot H2O (M = Rb, Tl). The reciprocal transformations of the components and phases of the M2O-V2O5-SO3 systems match the Lux-Flood ideas of the acid-base properties of oxide compounds.

  Potassium oxosulfatovanadate(V) K3VO2(SO4)(2) has been obtained by solid-phase synthesis from K2SO4, K2S2O7, and V2O5 (2: 1: 1), and its formation conditions, crystal structure, and physiochemical properties have been studied. The conversions of K3VO2(SO4)(2) in contact with potassium vanadates and other potassium oxosulfatovanadates(V) are considered in terms of phase relations in the K2O-V2O5-SO3 system, which models the active component of vanadium catalysts for sulfur dioxide oxidation into sulfur trioxide. The X-ray diffraction pattern of K3VO2(SO4)(2) is indexed in the monoclinic system (space group P2(1)) with unit cell parameters of a = 10.0408(1) , b = 7.2312(1) , c = 7.3821(1) , beta = 104.457(1)A degrees, Z = 2, and V = 519.02 (3). The crystal structure of K3VO2(SO4)(2) is built from [VO2(SO4)(2)](3-) complex anions, in which the vanadium atom is in an octahedral oxygen environment formed by two terminal oxygen atoms (V-O(6) = 1.605(7) , V-O(10) = 1.619(7) and four oxygen atoms of the two chelating sulfate anions. The vibrational spectra of K3VO2(SO4)(2) are analyzed using these structural data.

  The crystal structure of alkali-metal dioxovanadium(V) sulfates AVO(2)SO(4), where A is K or Rb, has been determined based on a combination of neutron and X-ray diffraction data. The compounds are isostructural and have an orthorhombic lattice (space group P2(1)2(1)2(1), Z = 4) with unit cell parameters a = 11.1004(2) and 10.8193(1) angstrom; b = 8.2626(2) and 8.9042(1) angstrom; c = 5.4772(1) and 5.5722(1) angstrom, respectively. The structures are of the chain type. Zigzag chains are formed by vertex-sharing VO6 octahedra. Sulfate groups SO4 link neighboring chains and form a spatial framework with cavities accommodating alkali-metal atoms with CN = 9 (K) and 8 (Rb). IR and Raman spectroscopy data are reported.
