Development of high-strength ash-free spherical carbon catalyst supports

Abstract

To develop technologies for carbon adsorbents, promising as catalyst supports, the use of synthetic monomer – furfural – for highstrength ash-free activated carbons with a spheroidal shape of the particles is justified. One-step process of resinification of furfural, forming a spherical product and its cure was developed, reducing production cycle times and reduce hardware costs. Derivatografic, X-ray diffraction, mercury porosimetry and adsorption studies of carbonization molded spherical product is made, it described the development of primary and porous structures of carbon residues. In combined-cycle activation of carbonized product a ashless active carbons are obtained with particles spheroidal shape, also well-developed capacity (up to 1,50 cm3/g) of sorbent microand mesopores and unique high mechanical strength– speed on the abrasion in 3 times smaller than that of commercial brands of activated carbons. The resulting activated carbons on the performance characteristics superior to all known brands of foreign and domestic counterparts, and are promising catalysts for working under harsh operating conditions – in the moving and fluidized beds.
