NUCt. EAR ENERGY DIVI $lON 5.2.2.1 Equipment. The following test equipment shall be used in perfonning this test:

Recording microbalance - with sensitivity ratio of weight change to a.

sample load of 1 x 10-6 g/g.

(Cahn Model "RG", Cahn Div., Ventron Instrument Corp., or Buyer appmved equivalent)

Vacuum Chamber - capable of 10-6mm Hg operation, surrounding the b.

sample pan of the microbalance, and associated vacuum equipment, so that the balance can be operated while the chamber is evacuated.*

Glassware - capable of injecting controlled amounts of Xenon or krypton c.

into the system, Thennometer (0.2'C division) - with ground glass joint, capable of d.

insertion in close proxity to the sample pan in the vacuum chaaber.*

Sam)1e Preparation. Activated carbon sLmples shall be preheated at 5.2.2.2 120^C for 4 tours and placed in a dessicator containing. anhydrous calcium sulfate (CaSO ) until equilibrated at room temperature, then placed in the 4

balance pan in the vacuum chanber, which shall be maintained at 2511*C as indicated by the internal thennometer.

2.2.3 Test Sequence. Test as follows:

The system shall be evacuated to 10-6 mm Hg for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> minimum, or a.

until the weight stabalizes, with the prepared carbon in place upon the balance pan, The vacuum side of the apparatus shall then be closed of f from the b.

weighing chamber and gas inlet and the exact weight of carton noted.

Xenon or krypton gas shall then be allowed to enter until a pressure c.

of 0.1 m Hg is obtained.

d.

Gas adsorption shall be allowed to continue until equilibrium is reached and no more weight gain is noted, admitting xenon or krypton periodically to maintain system pressure at 0.1 i.001m Hg.

Weight of the carton shall again be noted at the end of the test e.

period; the system can then be purged in preparation for the next test.

The difference between initial and final weights of the carbon 5.2.2.4 Res ul ts.

shall be considered the weight of krypton or xenon adsorted on the carbon; this value shall be converted to a volume in cubic centimeters at standard temperature This value, multiplied by 7600 to bring it to and pressure (STP - 0'C, I atm).

5.2.3 Determining Equilibrium Desorption Moisture Content. The equilibrium moisture on the activated charcoal at 25"C 33-percent relative humidity (R.H.)

shall be determined as follows:

5.2.3.1 Process.

Dried carbon is first exposed to high humidity and then to low htsnidity until it equilibrates, and the net retention of moisture is measured.

Specifically, air of 75-80 percent R.H. is passed through a sample of carbon until approximately 10 percent moisture is adsorted, after which air of 33 percent R.H.

is passed through until equilibrium is attained. The net gain in weight represents the equilibrium desorption moisture at 33 percent R.H.

5.2.3.2 Apparatus. Test equipment shall include, but not be limited to the following:

a.

Constant tenperature bath at 25'C.

b.

Three gas-washing bottles with fritted glass cylinders, 250 ml.

(Scientific Glass Apparatus No. 6069 or engineering approved equivalent): One to contain water, the other two for saturated magnesium chloride solution.

c.

Flowmeter:

1000cc air per minute.

J d.

Adsorption tube - (special construction; see Figure 2.1).

An ordinary U-tube, in which the sample fills both legs, should not be used because of the distorted air-flow pattern through it. The dimensions given in the diagram are for example only and need not be adhered to exactly.

The important point is that the carbon bed is contained as a vertical cylinder.

e.

Balance:

accurate to a centigram.

(See Figure 2.2 for the arrangement of the apparatus).

5.2.3.3 Test. The test shall be performed as follows:

a.

Dry a sample of carbon (at least 50 cc) at 130 C for 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

b.

Obtain the tare weight of the empty adsorption tube (weight A),

fill to the 10 cm mark (does not have to be exact) with dried sample and reweigh (weight B).

Place the tube in the water bath, c.

Pass air through just the water-wash bottle and then through the sample at a 1000cc/ min flow rate, until approximately 10 percent moisture is adsorbed, as determined by weighing.

The time required for this to occur varies with the type of carbon; usually 1-2 hours is sufficient.

Equilibrium Desorption Moisture (%) = w,[.

j.B x 100

,A o

Notes 1.

Passing air through a saturated solution of MgC12 at 25*C, is a convenient method of obtaining 33 percent R.H.

Other means of producing this humidity may be used, i.e. diluting a saturated air stream with dry air, but the humidity of the final air stream should be checked by an independent method.

2.

For cartons with equilibrium desorption moisture level well below O

10 percent (e.g.1 to 3 percent) it is not necessary to initially adsorb 10 percent. This level is specified to cover most carbon types. Actually, at the high-humidity level it is only necessary to adsorb several percent of water above the desorption equilibrium level. By reducing the amount first adsorbed, the time necessary to reach desorption equilibrium is reduced more than proportionally.

Of course, the final value must be known before the procedure is modified, but it is applicable as a means of quality control for different carbon lots from the same source.

5.2.4 Stirring Abrasion Test. An indication of the abrasion resistance of an activated carbon sanple is obtained by measurement of the percentage reduction of the average particle size resulting from the action of a T-bar stirrer in a special apparatus.

5.2.4.1 Apparatus. The equipment shall consist essentially of an inverted T-shaped stirrer turning rapidly in a cylindrical vessel containing the activated carbon. The clearance at the ends of the stirrer and bottom are the only critical dimensions. The speed of the shaft is 875 + 15 rpm. This speed is obtained with 2:1 reduction by a V-belt from a 1750 rpm motor,1/10 h.p.

or larger. A simple frame for holding the drive motor and bearing container assembly is also required.

Prepare a sample of activated carbon having a volume of 250 to a.

500 ml.

b.

Place the sample on the top (coarsest) sc: ten of a stack of U.S. Sieves numbers 12, 16, 20, 40, 50, and 70. Shake the screens for 15 minutes i 10 seconds on a Ro-Top sieve shaker.

c.

After the shaking period, the screens are removed from the shaker and the weight of the carbon on each screen is recorded.

Discard the -70 material.

d.

The remaining fractions are then recombined and blended, then introduced into the abrasion apparatus.

e.

The abrasion apparatus is operated for one hour i one minute, f.

After the stirring periodIthe carton is removed and rescreened (steps b and c).

Measure the -70 material in the bottom pan and record as the percent dust formation.

5.2.5.3 Calculations The average particle size, before and after stirring, is obtained a.

using the equation:

y " I WD IT W = weight of a mesh fraction in grams.
