Reaction Mechanism of Arsenic and Nitrogen Oxides in Coal Combustion

by Haoying Duan

Progress in Energy & Fuels, Vol.2, No.1, 2019; 106 Views, 7 PDF Downloads

The reaction mechanism of arsenic and nitrogen oxides (N2O, NO2 and NO) was studied by using density functional theory of quantum chemistry B3LYP method. All parameters optimize the geometric configuration of each reactant, intermediate, transition state and product. The authenticity of intermediate and transition state is confirmed by frequency analysis, and the transition state is further determined by calculation of intrinsic reaction coordinate (IRC). In order to obtain more accurate energy information, the single-point energy of each structure is calculated at B2PLYP level, and its reaction mechanism is deeply analyzed through kinetic parameters. The results show that the reaction energy barrier between arsenic and three nitrogen oxides (N2O, NO2 and NO) is 78.45, 2.58, 155.85kJ/mol respectively. At 298-1800 K, each reaction rate increases with the increase of temperature. Due to the low reaction energy barrier between arsenic and NO2, the reaction rate is greater than 1012 cm3/(mol s), indicating that the reaction is easy to occur and extremely fast. Arsenic reacts with N2O and NO at 298-900 K, and the reaction rate increases obviously with the increase of temperature. When the temperature rises further, its increasing trend slows down.

Progress in Energy & Fuels, Vol.2, No.1, 2019; 99 Views, 8 PDF Downloads

The Al-MCM-41 and Molecular Sieve with different aluminum loadings were prepared by post grafting method. Characterization of Molecular Sieves by XRD, N2 Adsorption- Desorption NH3-TPD, Py-FTIR and other methods. Evaluation of Thiophene Adsorption Performance by Fixed Bed. By correlating the thiophene adsorption capacity of molecular sieves with the acid properties and texture properties of molecular sieves, examine the influence of olefin presence on Al-MCM-41 and Adsorption and Desulfurization Mechanism of Active Site Species. The results show that the introduction of aluminum species produces B-type acid center, as well as two types of L acid center, L1 and L2. The introduction of low content aluminum species is beneficial to the formation of B-type acid centers and L1-type acid centers, while the introduction of high content aluminum species is beneficial to the formation of L2-type acid centers. Among them, L2-type acid center has the best adsorption effect on Thiophene. Olefins and thiophenes undergo competitive adsorption and catalytic conversion reactions at B and acid centers, and catalytic conversion reactions dominate. The existence of L2 acid center promotes the catalytic conversion reaction on the B acid center, and the generated macromolecular sulfide replaces thiophene to be adsorbed on the molecular sieve acid active center, thus improving the saturated sulfur adsorption capacity of Al-MCM-41 molecular sieve.
