SCR NO x mechanistic study with a mixture of hydrocarbons representative of the exhaust gas from coal combustion over Rh/Ce 0.62 Zr 0.38 O 2 catalyst

Abstract Several mineralogically, chemically and texturally diverse minerals and waste materials were selected for the testing of elemental mercury capture in exhaust gas, namely tyre char resulting from the burning of pyrolytic rubber tyres, class C fly ash, mesoporous material type MCM-41 and glauconite. Each material’s mineralogical, chemical and textural characteristics were explored. In order to conduct experiments in conditions similar to those during the contact of sorbent with real coal exhaust fumes at a temperature of about 110-120°C, the experiments were carried out using a test device consisting of a furnace for burning powdered coals, a thermostatic cage for sorbent reactors and mercury gas analysers, which are able to measure and compare the effects of individual sorbents with exhaust gas. The study found that the best results for mercury sorption in the exhaust atmosphere were obtained for class C ash resulting from brown coal combustion.

Toxic Trace Metals

INTRODUCTION“Acid rain” and “acid deposition” are terms no longer confined to the lexicon of atmospheric scientists and 1imnologists. Public awareness of and concern over this phenomenon, particularly as it affects acid-sensitive regions of North America, have increased dramatically in the last five years. Temperate ecosystems are suffering from decreased pH caused by acid deposition. Human health may be directly affected by respirable sulfates and by the increased solubility of toxic trace metals in acidified waters. Even man's monuments are deteriorating as airborne acids etch metal and stone features.Sulfates account for about two thirds of airborne acids with wet and dry deposition contributing equally to acids reaching surface waters or ground. The industrial Midwest is widely assumed to be the source of most sulfates reaching the acid-sensitive Northeast since S02 emitted as a byproduct of coal combustion in the Midwest dwarfs S02 emitted from all sources in the Northeast.
