โœฆ Synopsis

The thermodynamics and kinetics of the diethylbenzene-benzene transalkylation have been studied in liquid phase over faujasite Y in a batch reactor. The reactions were conducted at several temperatures between 423 and 513 K. The main product of the reaction was ethylbenzene.

When the molar ratio of benzene over diethylbenzene was greater than five, a selectivity in ethylbenzene greater than 90% was found. The initial rates showed that the transalkylation reaction followed a first order mechanism. A kinetic model is proposed. Dale, L. S. and Riley. K. W. Preps. Pap.--ilnt.

C/rem. Sec., Wt.. Fuel Chem., 1996, 41. (3) 756-760. New and improved analysis methods, based on modern spectroscopic techniques, are reported. The objective of these new methods is to provide more reliable data on the levels of environmentally significant elements in Australian bituminous thermal coals. Details of the methods are given and results of validation trials discussed on some of the methods which are anticipated to be designated Australian standard methods.

Pulverized coal injection (PCI) is employed in blast furnace tuyeres in order to increase the injection rate without increasing the amount of unburned char inside the stack. When coal is injected with air in the region of tuyeres, the resolidified char will burn in an atmosphere with progressively l
