This invention relates to a dispersion comprising porous particles dispersed in a liquid phase, wherein the porous particles comprise a zeolite and the liquid phase is a size-excluded liquid. The invention also relates to a method of adsorbing a gas into a liquid, comprising at least the step of bringing the gas into contact with the dispersion. In addition, the invention relates to an assemblage of the dispersion, the zeolite comprising a cavity and a gas contained within the cavity.

An apparatus includes a housing that defines a first zone, a second zone, a third zone, and a fourth zone. The apparatus includes an inlet, a first outlet, a second outlet, and a conveyor belt. The inlet is configured to receive a carbon dioxide-containing fluid in the first zone. The first outlet is configured to discharge a carbon dioxide-depleted fluid from the first zone. The second outlet is configured to discharge a carbon dioxide-rich fluid from the third zone. The conveyor belt passes through each of the zones. The conveyor belt includes a carbon dioxide sorbent. Within the first zone, the carbon dioxide sorbent is configured to adsorb carbon dioxide from the carbon dioxide-containing fluid to produce the carbon dioxide-depleted fluid. Within the third zone, the carbon dioxide sorbent is configured to desorb the captured carbon dioxide to produce the carbon dioxide-rich fluid.

The present invention provides an improved process for recovering CO from a catalytic fast pyrolysis (CFP) process product effluent. The process comprises the steps of: a) providing a first vapor phase stream resulting from a CFP process comprising, on a water-free and solids-free basis, from 25 to 80% CO and at least 15% CO.sub.2, b) mixing the first vapor phase stream of step a) with a particular solvent to make a mixed phase stream, c) separating the mixed phase stream of step b) into a second vapor phase stream comprising CO and a liquid phase stream, and d) recovering a product stream from the second vapor phase stream of step c) having a higher concentration of CO and a lower concentration of CO.sub.2 than the first vapor phase stream of step a).
