Isothermal Kinetics Modelling of the Fischer-Tropsch Synthesis over the Spray-Dried Fe-Cu-K Catalyst

Journal of Natural Gas Chemistry 2006年第2期15卷 105-114页

The isothermal kinetics of the Fischer-Tropsch synthesis （FTS） over Fe-Cu-K spray-dried catalyst was studied in a spinning basket reactor. The experiments were carried out at a constant temperature of 523 K, n（H2）/n（CO） feed ratios of 0.8 2.0, reactor pressures of 1.1 2.5 MPa, and space velocity of 0.556× 10^-3 Nm^3/kgcat·s. Kinetic model for hydrocarbon formation was derived on the basis of simplified carbide mechanism to reduce the number of parameters. Two individual rate constants for methane and ethene were considered. Furthermore, the model was modified empirically by non-intrinsic effect, such as physisorption and fictitious olefin pressures that were taken into account, and the influences of secondary reaction of α-olefins on product distribution. The simulation results showed that the experimental phenomena of FTS and the deviations from ASF distribution, such as the relatively high yield of methane and low yield of ethene observed experimentally could be depicted basically.

Evaluation of the Production of Young Green Barley Plants Containing Functional Ingredients

American Journal of Plant Sciences 2015年第2期6卷 323-333页

作者： Tianxiao Meng Chizuru Miura Nobuto Irino Ryuichiro Kondo Faculty of Agriculture Kyushu University Fukuoka Japan Asahi Ryokuken Co. Ltd. Fukuoka Japan

We conducted experiments to establish the growing conditions of hydroponic young green barley plants in which functional ingredients were applied and absorbed during the cultivation period. No studies have conducted experiments on functional ingredients applied during the cultivation of young green barley. In this study, glucosamine (GlcN) and collagen (Cgn) were used, both of which are widely known as functional ingredients and are in high market demand. In the GlcN application experiment, young green barley plants were cultivated with only liquid fertilizer during the early growing period for 9 days, and then the plants were cultivated in 0.25% GlcN-water solution for the following 3 days. The plants used in this experiment absorbed 0.60% of GlcN. Furthermore, an experiment was conducted to test plant absorption of collagen. Collagen absorption was evaluated using hydroxyproline (Hyp) as an indicator ingredient. Under control conditions, the Hyp content was 0.04% after 14 days of cultivation. Meanwhile, in the application experiment of Cgn derived from pigs (average molecular weight is 3000), plants were cultivated in 1% Cgn-water solution for 14 days. As a result, the Hyp content increased to 0.28%. Thus, this study clarifies, for the first time, that barley plants can absorb exogenous functional ingredients applied from the outside. The nutrient component contents in young green barley plants were measured. The amino acid and vitamin C content in hydroponic young green barley significantly increased, as compared to those grown in organic soil. Furthermore, in 0.1% Cgn-water solution cultivation, glutamic acid and aspartic acid, both of which are a functional amino acids, increased approximately three folds as compared to the plant grown in organic soil under natural sunlight. Furthermore, K and Na, which are inorganic ingredients in young green barley, were measured. The K content in the plants grown in 1% Cgn-water solution cultivation for 14 days decreased by
