Both calorimetric determination of displacement adsorption enthalpies ΔH and measurement of adsorbed amounts of lysozyme (Lyz) denatured by 1.8 mol L−1 guanidine hydrochloride (GuHCl) on a moderately hydrophobic packings at 298 K, pH 7.0 and various salt concentrations were
carried out. Based on the thermodynamics of stoichiometric displacement theory (SDT) the fractions of thermodynamic functions,
which related to four subprocesses of denatured protein refolding on the surface, were calculated and thermodynamic analysis
that which one of the subprocesses plays major role for contribution to the thermodynamic fractions was made in detail. The
moderately hydrophobic surface can provide denatured Lyz energy and make it gain more conformation with surface coverage or
salt concentration increment. The displacement adsorptions of denatured Lyz onto PEG-600 surface are exothermic, more structure-ordered
and enthalpy driven processes.

The recombination of hydrogen and oxygen in technical gaseous waste of nuclear power plants in enlarged scale experiment has
been studied on the basis of our previous work.1 The catalyst and its best operating conditions for recombination of hydrogen and oxygen determined in a small scale experiment
were demonstrated and tested. The results show that the data obtained in an enlarged scale experiment agreed well with that
of in a small scale test. The recombination rate of H2 and O2 was higher than 98.3% and 99.98% respectively. After recombination, the residual concentrations of H2 and O2 in waste gas were O2<3 ppm, H2<400 ppm. The Pd-Al2O3 catalyst and operating conditions determined for gaseous waste processing of nuclear power plants were satisfactory.

The recombination of hydrogen and oxygen in technical gaseous waste of nuclear power plants has been studied. A highly efficient catalyst for reacting H2 with O2 to form water was prepared. Various operating conditions and factors affecting the recombination of H2 and O2 were tested and the best conditions were determined. Results show that the Pd–Al2O3 catalyst prepared had very good characteristics. The recombination rate of H2 and O2 was higher than 98.3% and 99.9%, respectively. After recombination, residual concentrations of H2 and O2 in waste gas were O2<3 ppm, H2<400 ppm. The Pd–Al2O3 catalyst and operating conditions determined for gaseous waste processing of nuclear power plants were satisfactory.
