The manganese oxides (general formula MnO x ) are uniformly distributed over the surface of the laminar sorbents in the form of ultradisperse particles ( 2 /g. The peak of the micropore distribution for the composite sorbents corresponds to the mean pore diameter (2.1 nm)....
Using the room-temperature formulae obtained from the EXAFS results, the oxidation state of Fe can be calculated to be 3.2, 3.1, and 2.9 in LSF72, LSF82, and LSF92, respectively. Having a higher average oxidation state of Fe in LSF72 and a lower average oxidation state in LSF92 leads...
Pemberton replace the wine in his formula with a sugary syrup. The cocaine portion of Coca-Cola was removed before 1914 when cocaine was deemed illegal in the United States of America. Coca-Cola as we know today still contains coca but the narcotic portion of cocaine, it is removed. Today...
Apart from its petrographic properties, the bulk chemistry of the coal is also an essential consideration in coking operations. Coals with a high proportion of sulfur or phosphorus are generally unacceptable, since these elements are transferred to the coke and ultimately incorporated in the iron and...
1. A combination useful for reducing or preventing coke formation in thermal cracking furnaces, the combination being comprised of (A) one or more compound of the formula R—Sx—R′ wherein R & R′ are independently H, alkyl with 1 to 24 carbons straight chain or branched, aryl and x=...
A formula is derived for predicting the ignition temperature of 50 : 50 binary mixtures on the basis of the ignition temperatures of their components. It appears that, in the mixtures, the component with the lower ignition temperature is ignited first. The energy liberated is consumed in the ...

摘要: Since the inclination of central axis can indicate the stability of coke columns and also a base for measurement,in this paper,based on coordinates exchange formula,the least square method is used to do the precision measurement for coke columns central axis.关键词:...
The BLP calculation formula forces a rapid drop of rise as the result of relatively slight wind vector deviation from the direction of sources row axis, ending in minimal value at the angle 90°. This was observed during calculations, when the angle between wind vector and the banks of coke...
