suppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولRegulation of synthesis of glutamine synthetase by adenylylated glutamine synthetase.
We have examined three mutants of Klebsiella aerogenes whose genetic lesions (glnB, glnD, and glnE) are in loci unlinked to the structural gene for glutamine sythetase (glnA) and in which the control of both the level and state of adenylylation of glutamine synthetase is altered. Each mutation alters a different component of the adenylylation system of glutamine synthetase [L-glutamate:ammonia ...
متن کاملThermal aggregation of egg white proteins as affected by saccharides
Thermal characteristics of egg white proteins (EWP) may differ in the presence of saccharides. Therefore, the influence of saccharides including carboxymethyl cellulose (CMC), pectin, sucrose and maltodextrin and heating time on physicochemical characteristics of EWP as a whole were studied. Investigation of Heat Coagulation Time (HCT), solubility, turbidity and protein secondary structure of h...
متن کاملRegulation of glutamine synthetase. X. Effect of growth conditions on the susceptibility of Escherichia coli glutamine synthetase to feedback inhibition.
The kinetic properties of Escherichia coli glutamine synthetase are markedly influenced by the manner in which the organism is grown. Enzyme obtained from stationary-phase cells grown on glycerol and glutamate is strongely inhibited by each of the eight feedback effectors known to influence this enzyme; however, the enzyme from log-phase cells grown on glucose and growth-limiting concentrations...
متن کاملUnfolding and aggregation during the thermal denaturation of streptokinase.
The thermal denaturation of streptokinase from Streptococcus equisimilis (SK) together with that of a set of fragments encompassing each of its three domains has been investigated using differential scanning calorimetry (DSC). Analysis of the effects of pH, sample concentration and heating rates on the DSC thermograms has allowed us to find conditions where thermal unfolding occurs unequivocall...
