Denitration

Based on the results obtained by XRD, FE-SEM, TEM, NH3-TPD, UV-vis (DRS), XPS, the treatment of plasma was much essential for the transformation from Ce4+ to Ce3+ on the surface of Ce/TiO2 -palygorskite, to increase surface chemisorbed oxygen, and the improved dispersion, which were highly favorable for denitration.

The scope of the order calls for the MHPS group to: 1) supply the core parts for upgrading the FGD equipment, in order to improve the SOx removal rate; 2) deliver a denitration catalyst enabling outstanding NOx reduction; 3) revamp the electrostatic precipitator to enhance the particulates removal rate; and 4) perform engineering of a non-leak gas-gas heater (NL-GGH) enabling heat exchange and flue gas reheating.

The types and quantities of the desulfurization and denitration active groups in the surface of SBAC were enriched, which could help the adsorption and the oxidation of S[O.sub.2] and NO.

(7) The reactions of denitration and desulfurization processes are neglected in the combustion submodel due to the less influence on temperature field.

These radicals attack indiscriminately all species present in the reaction, oxidizing organic compounds by abstraction of hydrogen or engaging in double bonds and aromatic rings (hydroxylation), causing reactions such as demethoxylation, dehalogenation, dealkylation, denitration, deamination and decarboxylation [5, 6].

According to the contract, NF Energy will provide and install boiler denitration, dust removal and desulfurization systems two sets of equipment at the project for sulfur dioxide and nitrogen oxide emissions reduction and dust removal.

Protein tyrosine nitration: Selectivity, physicochemical and biological consequences, denitration, and proteomics methods for the identification of tyrosine-nitrated proteins.

All recent work is in agreement as regards a single NG denitration pathway under both aerobic and anaerobic conditions in which NG is used as a nitrogen source.

The technological improvement on denitration for coal-fired power companies hasbecome the top priority in the NOx emission reduction.
