Results include expressions for the concentration distributions of the solid and gaseous reactant, the propagation velocity of the conversion zone inside the particle, the conversion time and the conversion rate.
At a gas space velocity of 60,000 h−1, the conversion of carbon dioxide was 42% at 700 °C, which is very close to the equilibrium conversion of 44%.
At 870°C and space velocity of 900 h−1 the conversion degree of methane was 83.1%, that of CO2 was 62.7%, and the H2-selectivity was 76.5%.
The transesterification of cyclopentyl acetate and methanol was carried out under normal pressure, the reaction temperature of 50 °C, the molar ratio of methanol to cyclopentyl acetate of 3 1, the mass space velocity of 2.0 h−1, the conversion of cyclopentyl acetate was 55.3 %, the selectivity of cyclopentanol was 99.5%%, the yield of cyclopentanol was 55.0 %.
The slope of the reaction was calculated using softmax pro software and Vmax, the velocity of maximum substrate conversion, was recorded.
Using standard Michaelis-Menten kinetics [e.g., [ 43, 45]] implemented by the program KC3 (Bio-Tek Instreaction, initial reaction velocity of the enzymatic conversion of isocitrate to α-ketoglutarate was calculated using the linear portion of the curve (approximately 5 15 minutes).
Samples were incubated overnight in a humidified incubator (37 °C; 5% CO2) then blotted dry on tissue paper and weighed to allow calculation of conversion velocity (pmol/mg/day).
Under the conditions of specific energy input of 86 kJ/mol, total flow rate of 2.67 SLM, catalyst-bed temperature of 850 °C and gas hourly space velocity of 3200 h−1, CO2 conversion of 91% and CH4 conversion of 94% with H2/CO = 1 and nearly 100% H2 selectivity are achieved with a CO2 energy cost of 598 kJ/mol and an energy efficiency of 72%.
The effects of the superficial velocity of oxygen on the conversion of 2-ethylanthrahydroquinone and the extraction efficiency of hydrogen peroxide were investigated, separately.
In addition, pH had notable impact on the nucleation velocity of SnO2 and the conversion speed from SnO2 to SnS2 in further as well.
