Abstract
The present invention relates generally to compositions useful in adsorption and reactive processes comprising an adsorbent powder, such as a zeolite, and a binder mixed to form an agglomerate having a porosity of 0.30≦εp≦0.42 and a N2 pore diffusivity Dp≧3.5×10−6 m2/s and wherein the mean particle diameter of the crystalline zeolite powder is 10 μm or less; the mean particle diameter of the binder is 0.10 dA or less, and the binder concentration is 10% or less expressed on a dry weight basis.

A composition useful in adsorption and reactive processes comprising an adsorbent powder and a binder mixed to form an agglomerate having a porosity of 0.30≦εp≦0.42 and a N2 pore diffusivity Dp≧3.5×10−6 m2/s and wherein the mean particle diameter of the adsorbent powder is 10 μm or less;
- the mean particle diameter of the binder is 0.10 dA or less, and the binder concentration is 10% or less expressed on a dry weight basis.
An adsorption process for adsorbing or separating a more strongly adsorbable component from a fluid mixture containing at least one more strongly adsorbable component and at least one less strongly adsorbable component comprising contacting the fluid mixture with an adsorbent material which selectively adsorbs the at least one more strongly adsorbable component and the at least one less strongly adsorbable component is recovered as product and wherein
- the adsorbent composition comprises a crystalline adsorbent powder and a non-clay type binder having a porosity of 0.30≦εp≦0.42 and a N2 pore diffusivity Dp≧3.5×10−6 m2/s, and wherein the mean particle diameter of the crystalline adsorbent powder is 10 μm or less, the mean particle diameter of the binder is less than or equal to 0.10 dA, and
- the binder content is 10% or less expressed on a dry weight basis.
