The method for mixing sulphuric acid with water is carried out by supply of acid and water into a common vessel, which is sulphuric acid absorber. Acid into the absorber will be given with the concentration, which is less than 98.3 %, through the distributing plates of absorber to the ...
PROBLEM TO BE SOLVED: To decrease the amount and the volume of sewage sludge incineration ash, efficiently utilize the treated ash as a resource, provide a solid matter with high strength and scarcely eluting acids, heighten the plasticity of clay-like substance at the time of kneading, make ...
According to the pH value of mine water in different regions and industrial wastewater from different industries, the experiment designed five water pH values, namely 1, 4, 7, 10 and 13. The acidic water environment is diluted with sulfuric acid to a certain molar concentration, and the alkali...
The heats of mixing, HE, and heat capacities, at 25 °C, have been determined both for the ternary system: acetic acid–chloroform–water, and for the component binary systems: acetic acid–chloroform and acetic acid–water. The results are discussed in their bearing on the equilibria existing...
The acid can be sulfuric acid or a mineral acid. The gas which forms an acid upon contact with water can be carbon dioxide, sulfur dioxide, or other acidic forming gases. As used herein the phrase “long chain carboxylated carbohydrate” refers to carboxylated carbohydrates having average molecul...
A broader definition of an acid is any substance which ionizes in water to yield positive hydrogen ions; or any compound which can transfer a proton to another compound.The halogens (fluorine, chlorine, bromine, and iodine) can combine directly with hydrogen to form the strong acids, ...
Hydrocarbon feedstock containing resid is cracked by a process comprising: (a) heating the hydrocarbon feedstock; (b) mixing the heated hydrocarbon feedstock with steam and optionally water to form a mixture stream; (c) introducing the mixture stream to a flash/separation apparatus to form i) a...
of the resist pattern off the substrate with the mixed solution, the pure water tends to bring about a dissolving reaction with the sulfuric acid remaining on the substrate. What should be noted is that the dissolving reaction brings about the mist generation and scattering of the sulfuric acid...
A mesoporous carbon is prepared by mixing a carbon precursor, an acid, and a solvent to obtain a carbon precursor mixture; impregnating an ordered mesoporous silica (OMS) with the carbon precursor mixture; carbonizing the impregnated OMS at 800 to 1300掳 C. by irradiating microwave energy with...
Optical measurement of the evaporation of sulfuric acid droplets Single micron-size sulfuric acid droplets are levitated in vacuum in a quadrupole trap through which passes the beam from a He–Ne laser. Scattered light i... CB Richardson,RL Hightower,AL Pigg - 《Applied Optics》 被引量: 76发...
