A gas separation process uses a structured particulate bed of adsorbent coated shapes/particles laid down in the bed in an ordered manner to simulate a monolith by providing longitudinally extensive gas passages by which the gas mixture to be separated can access the adsorbent material along the length of the particles. The particles can be laid down either directly in the bed or in locally structured packages/bundles which themselves are similarly oriented such that the bed particles behave similarly to a monolith but without at least some disadvantages. The adsorbent particles can be formed with a solid, non-porous core with the adsorbent formed as a thin, adherent coating on the exposed exterior surface. Particles may be formed as cylinders/hollow shapes to provide ready access to the adsorbent. The separation may be operated as a kinetic or equilibrium controlled process.
A structured adsorbent particle comprising a thin film adsorbent coating on the exterior of a low permeability core wherein a minimum cross-sectional dimension of the particle is less than 1 centimeter and greater than 100 microns.
A structured adsorbent module comprising a multitude of adsorbent particles arranged in a mass, wherein the adsorbent particles are substantially oriented in a similar direction, which mass is supported in a module configuration to substantially maintain the orientation of the adsorbent particles therein, and the adsorbent particles have a length to maximum cross-sectional dimension of at least 2:1.
A gas separation process comprising contacting a gas mixture containing at least one contaminant with an adsorbent bed of structured adsorbent particles comprising a thin film adsorbent coating on the exterior of a low permeability core wherein a minimum cross-sectional dimension of the particles is less than 1 centimeter and greater than 100 microns.
A kinetic gas separation process which comprises contacting a stream of a gas mixture comprising natural gas containing contaminants including carbon dioxide and/or hydrogen sulfide, with an ordered adsorbent bed having a void fraction of not more than 33% and being comprised of adsorbent particles laid down in the adsorbent bed in an ordered configuration to provide substantially longitudinally extensive, substantially aligned gas channels by which the gas mixture contacts the adsorbent material along the length of at least a proportion of the particles to cause adsorption of at least some of the contaminants and to form a purified natural gas product having a reduced content of the adsorbed contaminant material.
A method of forming an adsorbent bed of ordered adsorbent particles for treating a gas stream to remove gaseous contaminants from the stream, which comprises laying the adsorbent particles down in a mass in an ordered configuration to provide substantially longitudinally extensive, substantially aligned gas channels by which the gas mixture contacts the adsorbent material along the length of at least a proportion of the particles, cohering the particles in the mass to form a coherent, self-supporting mass and assembling a plurality of the masses in an adsorption vessel to form an ordered adsorbent bed.
A method of making a simulated adsorbent monolith for separating components of a gas stream, which comprises:
