In previously reported experiments we have converted caking coals to noncaking coal char by treating coal of 1/8—1-1/2 in. for 3 hours in static bed (3), coal of 18-100 Tyler mesh size for 5 min. in a fluidized bed (I), and coal of 4-8 Tyler mesh in size for 2 sec. in free fall (2). Nitrogen and carbon dioxide, steam, or a mixture of all three with small amounts of oxygen were used as the heating and treating gas. [Pg.9]

Sieving is a standard operation for separating powders according to particle size using woven wire screens. The Tyler mesh size represents the number of openings per inch or the number of parallel wires that form the opening. [Pg.19]

Shape Density — This measurement can be of significant moment to adsorption performance despite it being relevant to only a single granule. This is because, for a given granule shape and size, shape density depends upon porosity of the activated carbon. For a cylindrical shape as 4 x 6 Tyler mesh size, a typical value is 1.4 g/cc (87 Ib/CF) to 1.5 g/cc (94 Ib/CF). [Pg.183]

Anatase with relatively large particle size was prepared by heating the freshly prepared oxide to 400°C anda sample of particle size 74> Pi > 53 microns was obtained by employing Tyler standard sieves (- 200 + 270 mesh). These particles were crushed to finer particles and sieved (mesh sizes -270 + 325 and -325) to provide anatase samples (P2and P3) with particle sizes 53>P2>43 and P3<43 microns respectively. Since the thermal history of all the three samples is the same, it was assumed that any changes in transformation characteristics can be attributed to particle-size effects. The kinetics of transformation of the three samples were studied at 700°C and the transformation curves shown in fig. 4a, clearly indicate that smaller particle size of... [Pg.134]

Calculate the crystal size distribution function n. The crystal size distribution for the ith sieve tray is n, = 1012M3AVTj/(L3ALj), where AIT, is the weight fraction retained on the ith screen, /., is the average screen size of material retained on the ith screen (see Example 10.7, step 2), and A/., is the difference in particle sizes on the ith screen (see Example 10.7, step 3). For instance, for the Tyler mesh 100 screen, nio = 1012(0.119)(0.040)/(1613 x 28) = 40.7 crystals per cubic centimeter per micron. Table 10.5 shows the results for each sieve screen. [Pg.407]

Catalyst particles size -35 -i-48 Tyler mesh were used in all tests. Porosity was measured using a mercury porosimeter. A 0.1356 pm pore mean diameter was determined. The Satterfield and Sherwood (7) methodology was used to verify that reaction occurs without any diSusional limitation (internal or external). The effective diffusivity was estimated from the porosity measurements and binary diffusion coefficient and pore tortuosity pubhshed in the hterature, leading to an estimated value of 10 for the generahzed Thiele Modvdus based on the reaction rate. The efi ectiveness factor was then considered as 1.0. [Pg.1194]

Size and condition of the urea. This was previously mentioned but is re-emphasized because of its extreme importance. The substrate material graphed in Figure 5 was spherical, smooth, and closely sized. Its Tyler screen size is +6 mesh = 0%, —6 +7 mesh = 9%, —7 +8 mesh = 70%, —8 +9 mesh = 19%, —9 mesh = 2%. [Pg.51]
