Abstract
An assemblage of substantially round particles with a mean diameter between 0.1 and 4 mm, more preferable between 0.3 to 2 mm and most preferable between 0.8 to 1.2 mm, wherein the density of the assemblage determined by ISO 697 is between 250 kg/m3 and 400 kg/m3 is disclosed. The substantially round particles comprise at least one microporous material and optionally at least one binder, wherein the assemblage comprises a pore volume, wherein the pore volume comprises pores resulting from void space between different ones of the substantially round particles and pores within the substantially round particles.

An assemblage of substantially round particles with a mean diameter between 0.1 and 4 mm, more preferable between 0.3 to 2 mm and most preferable between 0.8 to 1.2 mm, wherein the density of the assemblage determined by ISO 697 is between 250 kg/m3 and 400 kg/m3 and wherein the substantially round particles comprise at least one microporous material and optionally at least one binder, wherein the assemblage comprises a pore volume, wherein the pore volume comprises pores resulting from void space between different ones of the substantially round particles and pores within the substantially round particles.
A method for the manufacture of an assemblage of particles comprising:
- dispersing a zeolite powder in water to form a suspension;
- adding a polymer binder to the suspension and mixing to form a zeolite-polymer suspension;
- producing droplets of the zeolite-polymer suspension through a concentric double nozzle;
- enabling falling of the droplets into a liquid nitrogen solution to produce the particles.
