Embodiment 1

[0076] Example 1 is a compression molded cylindrical sorbent article according to the invention comprising 80 wt% of CECASiliporite ® Nitroxy ® SXSDM beads (lithium-exchanged LSX zeolite) and 20 wt% Arkema Kyblock TM FG-81 resin. The article of Example 1 has a high bulk density and excellent mechanical integrity. In order to manufacture the product, 20wt% of Arkema Kyblock TM FG-81 resin was added to 80wt% CECASiliporite with an average particle size of 0.52mm ® Nitroxy ® SXSDM beads. Kyblock TM FG-81 is sold as 1-10µm volume average size aggregates consisting of resin particles with an average volume size of 150-300nm.

[0077] The two components were hand mixed into a homogeneous mixture in a mixing bowl with a synthetic mixing paddle using low shear brushing techniques for 15 minutes until the binary blend was a homogeneous mixture. While mixing, preheat the forming die to 180°C in an oven. Once the forming die reached an equilibrium temperature of 180°C, ...

Embodiment 2

[0082] Example 2 Made of 95wt% CECA Siliporite ® Nitroxy ® SXSDM beads and 5wt% ArkemaKyblock TM Compression molded cylindrical adsorbent products composed of FG-81 resin. The article of Example 2 has a high bulk density and excellent mechanical integrity. To manufacture the part, 5wt% of Arkema Kyblock TM FG-81 resin added to 95wt% CECA Siliporite ® Nitroxy ® SXSDM beads. The LSX zeolite content analyzed by XRD was 79% by weight relative to the total weight of the article.

[0083] The two components were hand mixed into a homogeneous mixture in a mixing bowl with a synthetic mixing paddle using low shear brushing techniques for 15 minutes until the binary blend was homogeneous. While mixing, preheat the forming die to 180°C in an oven. Once the forming die reached an equilibrium temperature of 180°C, the mixture was added to a 5.42 cm diameter forming die and compressed using a pressure of 87 psi (0.6 MPa) for 1 minute. The article was then manually removed ...

Embodiment 3

[0087] Example 3 Adopt the CECA Siliporite of 95wt% according to embodiment 1 ® Nitroxy ® SXSDM beads and 5wt% Dakota UNEX EVA T1 resin (grade 0-200μm) were prepared. The LSX zeolite content analyzed by XRD was 79% by weight relative to the total weight of the article. The following characteristics of the article were determined according to the techniques described below:

[0088] Crushing strength value: 2.6MPa.

[0089] Abrasion value: 1.3%.

[0090] Volumetric efficiency: 0.164g / cm 3 .

Abstract

The present invention relates to an adsorbent article with reduced attrition due to immobility of its components, said article comprising zeolitic particles of at least one zeolitic adsorbent, said particles being immobilized with at least one resin, wherein the average particle size of the at least one zeolitic adsorbent ranges from 0.03 mm to 3 mm, and wherein the zeolite content is equal to orgreater than 60 wt%. The invention also relates to a method for separating a fluid from one or more other fluid(s) and / or separating a fluid from impurities contained in said fluid, comprising the step of contacting said fluid with at least one of said adsorbent article. Lastly, the invention relates to a blend of zeolitic particles and at least one resin, wherein the resin is preferably in the form of particles.

Description

technical field [0001] The present invention relates to adsorbent preparations comprising particles of one or more zeolites and one or more clays, said particles being bound together with one or more organic resins such as polymers, especially thermoplastic polymers . The sorbent has a high zeolite content which ensures a rapid diffusion of the fluid and a better stability of the sorbent due to reduced and even avoided attrition between the particles due to the immobilization of the particles within the article. Background technique [0002] US 2006 / 0166819 discloses resin-bonded sorbents for use in air-conditioning and refrigeration drying appliances. The adsorbent is added in the form of a powder, eg zeolite powder, which is dispersed in the resin prior to injection or molding. The sorbent content is relatively low (25wt%-55wt%) and the adsorption kinetics are very slow, making it an unsuitable material when high adsorption and desorption kinetics are required. [0003]...
