    Abstract: Extruded pellets comprising a majority of activated carbon particles and an organic binder provide improved performance when processed through tumbling equipment while the pellets are in their "green" state, i.e., pellets which are fresh off the extruder and contain activated carbon, binder, and water and have not been subjected to any thermal processing (drying). The tumbling action both smoothes the pellets (by closing any cracks and greatly improving appearance) and increases the density of the packed bed, e.g., by increasing particle density and reducing voids between the pellets. Improved performance results from an ability to increase the weight of carbon pellets which can be packed into a fixed volume and thereby increase the volumetric working capacity of the bed for adsorbing/desorbing vapors. Another benefit is to greatly reduce the levels of dust associated with the carbon, both the initial dust and the dust attrition.

    Abstract: An improved process for the production of catalysts comprised of a metal hydrogenation component, or components, composited with high pore volume alumina, with pores of narrow pore size distribution, wherein macropore volume is drastically reduced by improved extrusion techniques. An alumina hydrogel paste is extruded through a die to form spaghetti-like extrudate shapes by application of sufficient torque, suitably from about 25 to about 55 inch-pounds, preferably from about 40 to about 50 inch-pounds, to eliminate much of the macropore volume, i.e., pores greater than 400A, which greatly improves the activity maintenance of the catalyst. The extrudates can, if desired, be shaped into other forms, suitably spheres. The improved process also embodies a technique for increasing the intrinsic activity of these and other catalysts by special impregnation techniques which provides better dispersion of the metal hydrogenation component, or components, throughout the catalyst.

    Abstract: A process for the formation of a catalyst of predetermined pore size distribution and pore volume from an alumina hydrogel formed and obtained by precipitation from a solution containing a hydrous form of alumina in 1-5 wt. % concentration and an anion that is soluble in an alkaline solution and forms an aluminum salt, at pH 8-12, and temperature ranging about 15.degree. F.-120.degree. F., and then extended by contact with a water-soluble polymer containing from 2 to about 24 monomer units from the group consisting of (a) polyethylene glycols, (b) polypropylene glycols, and (c) polyethylene amines sufficient to absorb the polymer and displace water from the pores until the weight ratio of polymer:alumina ranges about 0.5:1 to about 4:1. The so formed alumina hydrogel in a series of steps, inclusive of the polymer extending step, is blended with make-up and recycle polymer for displacement of water and incorporation of the polymer, spray dried to convert the hydrogel to essentially boehmite powder of microspherical form, the boehmite powder mulled with water to form a paste, and the paste extruded to form extrudates. If desired, the extrudates are marumerized to form spheres. The extrudates or spheres, as desired, are extracted with a solvent to remove the polymer, and the alumina is then dried and calcined to form gamma alumina. In formation of the catalyst, a metal hydrogenation component, or components, is added during the initial alumina hydrogel forming step, added to the hydrogel after its precipitation from solution, or added to the gamma alumina after calcination.
