This invention is directed to an improved method for preventing deposition residue buildup on the internal surfaces of an ALD reactor chamber. In an ALD deposition process, the surfaces of a substrate are treated with an initiating precursor generating a labile atom reactive with a deposition precursor. Excess initiating precursor is removed from the reactor and the substrate surface then is exposed to a deposition precursor reactive with the labile atom under conditions for generating a fugitive reaction product containing the labile atom and leaving a deposition product. The process is repeated generating alternate layers of initiation and deposition precursor reaction products. The improvement in the ALD process resides in passivating the internal surfaces of the reactor by removing labile atoms reactable with either the initiating or deposition precursors prior to effecting ALD deposition.

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.

The invention discloses a rotating-type grain distributor and a granary provided with the grain distributor, and belongs to the technical field of granaries. The rotating-type grain distributor comprises a grain collecting barrel. The grain collecting barrel comprises a barrel wall and a barrel bottom. The outer side of the barrel wall of the grain collecting barrel is provided with two downward-inclined grain sliding pipes. The bottom face and one side face of each grain sliding pipe are curved surfaces which are of an integral structure. When the rotating-type grain distributor is used, the rotating-type grain distributor is arranged at a grain inlet of the granary, after grain enters the grain collecting barrel, the grain flows into the grain sliding pipes, and when the rotating-type grain distributor rotates, the grain sliding pipes rotate along with the rotating-type grain distributor. Due to the fact that the bottom face and one side face of each grain sliding pipe are curved surfaces which are of the integral structure, when the rotating-type grain distributor rotates, under the effect of centrifugal force and tangential force generated by the curved surfaces, the grain is scattered and flows out of the grain sliding pipes, and the grain falls onto a circular cross section of the granary. According to the rotating-type grain distributor, the impurity accumulation caused by automatic grading formed by concentrated falling of the grain is alleviated, and the safe storage of the grain is guaranteed.
