Tamizar catalizador de pentóxido de vanadio de ..masa del convertidor.. would = sift out pentoxide vanadium catalyst from the first mass ?? -------------------------------------------------- Note added at 5 hrs (2008-04-09 22:30:07 GMT) -------------------------------------------------- Hi again, I have found a bit more information: El principio empleado en la clasificación para producir la separación, depende de la magnitud de los tamaños de las partículas que componen el sistema. Cuando se trata de tamaños gruesos la separación se produce por el impedimento físico de una superficie provista de aberturas, la que retiene sobre ella aquellas partículas con tamaños mayores que su abertura; en este caso la operación se denomina “Harneado”. Cuando los tamaños de la distribución son relativamente pequeños, la separación se realiza haciendo uso de principios hidrodinámicos (sedimentación) y la operación recibe el nombre de “clasificación”. No existe un tamaño de partícula que representa una frontera entre la aplicación de estos dos principios, sino que más bien ésta queda definida principalmente por la eficiencia de los equipos, la magnitud y la naturaleza de la operación. HARNEADO Es una operación de amplio uso industrial, presentando una gran variedad de equipos. Se realiza normalmente sobre materiales gruesos, perdiendo eficiencia rápidamente con la disminución del tamaño de la partícula. En forma simple un harnero es una superficie con una multiplicidad de aberturas de una cierta dimensión. De tal forma que al pasar un sistema particulado sobre ella retendrá encima las partículas con tamaños mayores que la abertura, dejando pasar las de tamaño menor. Estas superficies están constituidas por barras paralelas, placas perforadas o mallas de alambre.

The spent catalyst becomes inactive and must be withdrawn from the catalyst reactor, and passed to a regenerator where coke is burned off to regenerate the catalyst, which is returned for reuse in the reactor. In addition to contamination, continued use of the catalyst results in catalyst attrition, i.e., the generally cylindrical catalyst particles become reduced in length to an undesirable degree. The presence of such shortened catalyst particles in a fixed bed reactor causes plugging of the bed and undesirable pressure buildup resulting in reduced flow and eventual shutdown of the bed. Historically, the catalyst industry has utilized classical screening techniques to remove "dust" or "fines", i.e., very small broken or deformed catalyst particles, from the catalyst mass. However, use of a screen with a square aperture is limited by the diameter of the generally cylindrical catalyst particle or "pill". If the aperture of the screen is larger than the cross-sectional diameter of the pill, the screen cannot separate the catalyst pills on the basis of length. Screening can only be used to separate pills having a length-to-diameter ratio (L/D) less than one from pills having an L/D equal to or greater than one. Thus, a 12 mesh screen (square or slotted) having a 1.7 millimeter opening, which is either square or rectangular, will allow a 1/16 inch (1.6 mm) diameter cylindrically shaped catalyst particle through the opening, whether the catalyst is 2 millimeters or 10 millimeters in length, as long as the catalyst enters the opening on end. Accordingly, in practice, the use of screening techniques is limited to removal of catalyst dust or fines in which the catalyst L/D is less than one. -------------------------------------------------- Note added at 6 hrs (2008-04-09 22:47:11 GMT) -------------------------------------------------- ANd I found this on another patent site: catalyst particles by sifting said crumbled mass through a screen. -------------------------------------------------- Note added at 6 hrs (2008-04-09 22:48:59 GMT) -------------------------------------------------- Process for extending life of coal liquefaction catalyst - Patent ... ... relatively small ash and coal-containing particulate impurities are separated from catalyst particles by sifting said crumbled mass through a screen. ... www.freepatentsonline.com/4157291.html - 56k - Cached - Similar pages Single-batch process to prepare noble metal vanadium alloy ... ... dried, sifted through a fine mesh screen and heat treated at about 927° C.
