NOVELTY - Structured adsorbent particle comprises a thin film adsorbent coating on the exterior of a low permeability core, where a minimum cross-sectional dimension of the particle is less than 1 cm and greater than 100 microns.    USE - The structured adsorbent particle is useful for separating gas, preferably kinetic gas, and for forming an adsorbent bed of ordered adsorbent particles for treating a gas stream to remove gaseous contaminants from the stream (all claimed).    ADVANTAGE - The structured adsorbent particle removes gaseous contaminants from the stream with economical manner.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a structured adsorbent module comprising a multitude of adsorbent particles arranged in a mass, where 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 in it, and the adsorbent particles have a length to maximum cross-sectional dimension of at least 2:1;    (2) 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;    (3) a kinetic gas separation process comprising 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;    (4) forming an adsorbent bed of ordered adsorbent particles for treating a gas stream to remove gaseous contaminants from the stream comprising 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 the masses in an adsorption vessel to form an ordered adsorbent bed; and    (5) making a simulated adsorbent monolith for separating components of a gas stream comprising forming a coat of a adsorbent material which is selective for adsorption of at least one of the components of the gas stream on the outsides of solid, non-porous particles having a length to maximum cross-sectional dimension ratio of at least 2:1 and a maximum cross-sectional dimension of not more than 1 mm, laying the adsorbent particles down in a mass in an ordered configuration with substantially longitudinally extensive, substantially aligned gas channels by which the gas stream may contact the adsorbent material along the length of at least a proportion of the particles, externally supporting or cohering the particles in the mass to form a coherent, self-supporting mass, and assembling the masses in an adsorption vessel to form an ordered adsorbent bed.
