a fire may also give off tiny solid particles of soot or ash. Additional gases may be released from incomplete combustion, especially of "dirty" fuel, such as carbon monoxide or sulfur dioxide.
Sulfur powder Sulfur dioxide Sulfuric acid Sodium sulfide相关知识点: 试题来源: 解析 答案:Sulfur powder。“Sulfur powder”是硫磺粉,是黄色固体且是硫的一种形式。“Sulfur dioxide”是二氧化硫;“Sulfuric acid”是硫酸;“Sodium sulfide”是硫化钠,都不符合黄色固体且是硫的一种形式这一条件。反馈...

The method involves considering that desorption of sulfur is carried out under the form of sulfur dioxide only when richness of an air/fuel mixture is greater than 1 and in the presence of surface oxygen in a catalytic converter (4). A rich air/fuel mixture is changed to a weak air/fuel...
Thus, the Mn-catalytic heterogeneous reaction might contribute 69.2 ±5.0% to the particulate sulfur. Consistently, stable sulfur isotope results supplied solid field observation evidence that TMI-catalytic reaction can be the dominant pathway for sulfate formation. TMIs contributed 49 ±10% to ...
The hollow glass part is filled with dry air or inert gas and sealed by butyl glue, sulfur glue or structural sealant.C) Insulating glass unit is filled with the inert gas is excellent in heat and sound insulation, meeting the requirement for savin...
A water stream containing a water-soluble sulfite compound is treated in order to reduce its total sulfur content while minimizing the formation of sulfate byproducts by the steps of: (a) converting the sulfite compound contained in the water stream to the corresponding thiosulfate compound; (b)...
Desulfurization of refinery main products such as petroleum gas, gasoline, jet and diesel fuels lubricants, bitumen, wax and petrochemicals is of environmental, health and economic values towards meet changing societal needs [1]. Achieving low sulfur (<10 ppm) or zero content in transportation fu...
Semiconductor materials include – Silicon, antimony, arsenic, boron, carbon, germanium, gallium arsenide, selenium, silicon carbide, sulfur, tellurium, oxides of most metals.What is Superconductor?Superconductor is an element, inter-metallic alloy, or a compound that conducts electricity without ...
