查询词典 activity energy

Linear solvation energy relation was firstly introduced in the paper, and the method and step of gaining the special parameters of solvent and solute were introduced in detail, and these special parameters were used to selection and optimization of extractive agent in extractive distillation. The model of predicting activity coefficient at infinite dilution was established by linear solvation energy relation. By the above theory, several candidate solvents were selected to separate C5 fraction, and by experiment of vapor-liquid phase equilibrium at atmosphere pressure, the mixture of N-methyl-pyrrolidone including 4% water was used extractive agent of separating C5 fraction. Then binary vapor-liquid phase equilibrium of the some compound in C5 fraction and N-methyl-pyrolidone were determined at atmosphere pressure and correlated by NRTL equation. Isoprene being objective compound, experiments were operated in the laboratory-scale column; the processes were simulated by RadFrac model in ASPEN PLUS. And by the combination of experiment and simulation, the new process of separation of C5 was established.

The study shows that: evergreen broad-leaved species during the middle and later period succession have better adaptability under the different light surroundings, such as Elaeocarpus glabripetalus, Ilex integra, Photinia prunifolia, Cinnamommum camphora. And Fluorescent Characteristics also verifies the above result. The experiment results indicate that: PSⅡreaction centers of majority tree species are not marked oxidized under the full light surroundings. Photosynthetic electron transport activity can maintain highly, in this way, it is helpful to enhance radiant energy dissipation and thus dissipate excess light energy. That is to say, the increase of non-photochemical quenching coefficient can conduce to protect PSⅡ, and mitigate the effect of high light on photosynthesis.
