摘要： A method of forming a batch of porous catalytic carrier filaments may include providing a precursor mixture, forcing the precursor mixture at a fixed rate through an orifice and then through a multiplicity of perforations in a belt, where the belt moves across and in tight registry with said orifice to form a batch of precursor catalytic carrier filaments, drying the batch of precursor porous catalytic carrier filaments to form the batch of porous catalytic carrier filaments, and firing (i.e. calcining) the batch of greenware porous catalytic carrier filaments to form the batch of porous catalytic carrier filaments. The batch of porous catalytic carrier filaments may have an average pore volume of at least about 0.1 cm3/g.
