The results showed that methanol conversion at 523 K reached a maximum of 41.6% with a CO2 selectivity of 94.6% and an outlet CO concentration of 1.26% over the catalyst reduced at 523-573 K.
synthetic products could be obtained with SiC content of more than 50% and SiO2 conversion rate of more than 90% under the conditions of the synthesizing temperature at 1460℃,two hours holding time,10% carbon in excess,6% sawdust,material granularity of about 0.5-0.3mm,and 2% catalysts and mineralizers.
The ace product rate increases from the average value of 71.9% in 1983,which is also the highest achievable in the past,to that of 94.2% and the butadiene conversion rate from 84.1% to 88.8%.
When the NH4+/Fe2+mol ratio is 3.5, FeSO4 concentration is 0.8~1.0mol/l, reaction temperature is 40 , reaction time is 30min, the conversion ratio of Fe2+ to Fe3+ is 99%.
Reaction time is 2 hours. It last under it is at response condition K + conversion ratio for 63. 5%, K2O content(%) of the products potassium sulfate is 47. 3%.
The experiments show that the percent conversion of strontium carbonate production is highest under the following conditions: calcium dichloride:0.5%~1%, temperature:1 150~1 200 ℃, reaction time:30 min, rate of lazurite to coal:1∶0.6, granularity of lazurite and coal:20~40 mesh.
Percent conversion of the green compact contenting higher diluents was higher than the lower one. With the increasing of diluents contents, the relative density of products also increased.
Having sifted some of synthetic processes and had a discussion over processing parameters such as reaction tem- perature percent conversion, raw material etc, a simple and convenient one suitable to the condition of our county was found.
Recycle reactor has been widely used and it is convenient to control the reactant concentration,the final percent conversion and the yield of target product.
Aldose reductase (AR) is an enzyme that catalyzes the conversion of glucose to sorbitol, which is in turn converted to fructose by sorbitol dehydrogenase.
The conversion of CNB could reach 99.9%, and the dechlorination of chloroaniline (CAN) was less than 1.9% when catalyzed by Pt-Sn-B/CNTs and more than 8.0% when catalyzed by common hydrogenation catalysts.
With thinner membrane and higher sweep ratio, methane conversion rate increases with high reforming pressure, which will change the unfavorable condition of high pressure of HTGR methane reforming hydrogen production system into a favorable one.
The methanol conversion rate and the gas permeability of the membrane depend considerably on the methanol vapor and gas (H2, He, CO2, Ar, CH4) flow directions.
After taking into consideration the influence of the pressure and carbon conversion ratio on the performance of the system, the gasifier and the combustor were synthetically studied.
A 2-propanol and phenylisocyanate reaction under an RF field of 6.3 kV/cm could reach 90 percent conversion in less than 150 seconds, yet it took more than 30 min without the exposure to an RF field.
A compelling inverse trend (p >amp;lt; 0.001) was demonstrated between the percent conversion of glucan to ethanol during SSF and the Klason lignin content of the wood samples before dilute acid pretreatment.
