How to determine the load when the load is loaded
The amount of active components and additives is an important factor affecting the catalytic performance of the catalyst, the active components, the amount is too small, the activity of course, with the increase in the amount of load, the activity slowly increased, but generally have An optimum value, greater than the optimal value of the time, the activity is basically the same, even due to the load is too large caused by metal sintering,
Determination of carrier water absorption in advance, with reference to molecular sieve water absorption measurement standards, according to the amount of preparation of immersion liquid. Impregnation liquid = carrier water absorption ------ equal volume impregnation impregnation liquid> carrier water absorption ----- excessive impregnation wet impregnation is only relatively dry mixing, the above two kinds of impregnation methods are wet Impregnated.
I wonder if you have learned the method of asking for extreme values. The function has a first derivative of 0 at the extreme (max or min) point. Find the value of the argument R when the derivative of the function P = E ^ 2 * R / (R + r) ^ 2 is zero. At this time the P is the maximum value. Let the output impedance r of the amplifier be constant, and for the above equation, P '= f (R)', then let P '= 0, we can get R = r
A certain amount of material by adding excess water, immersed for a period of time after the filter, calculated by the amount of material to be adsorbed by the amount of water, so as to get the saturated adsorption capacity of the material bolted (station contact TA) recommended the use of insects have resources bingyu0729 ( Station contact TA) take a certain amount of material measured its saturated adsorption volume, then this part is behind the impregnation of the precursor ...
Wanglilove (station contact TA) is generally enough for a day, in order to completely impregnated, the best long time, so that the lack of immersion hulei1049 (station contact TA) the best time long, let it slowly adsorption! Zhangwei643 (station contact TA) can be a few hours! Lingliaopiao (station contact TA) not so exaggerated, the general two or three hours on the complete .
