A canister that adsorbs and desorbs evaporative fuel generated in a fuel tank of a vehicle includes an adsorbent and a tubular body. A contact surface that is at least a partial area of an inner wall surface of the tubular body in a length direction of a central axis is brought into contact with a side surface of the inserted adsorbent to suppress movement of the adsorbent in a direction orthogonal to the central axis. The tubular body has an inclined surface in which the inner wall surface is inclined in a direction approaching the central axis of the tubular body in at least a partial area of an area from a starting point to the contact surface, the starting point being an opening end of an opening into which the adsorbent can be inserted.

The present invention provides a metal-organic framework material for the adsorptive separation of acetylene/ethylene mixture and preparation method therefor. The metal-organic framework material is named TJE-2 with a chemical formula of [Ni(pyc)(apyz)].sub.n, wherein, Ni represents nickel as a metal center, pyc represents the organic ligand 1H-pyrazole-4-carboxylic acid, and apyz represents the organic ligand 2-aminopyrazine. The preparation method is as follows: thoroughly dissolving pyc, apyz and Ni(NO.sub.3).sub.2.Math.6H.sub.2O, transferring the mixture to a pressure-resistant closed container for heating reaction, followed by solvent exchange and activation to obtain a homogeneous powder material. The ultra-microporous metal-organic framework material prepared by the present invention features a significantly high C.sub.2H.sub.2 adsorption capacity, good selectivity, and low raw material costs, and therefore can realize C.sub.2H.sub.2/C.sub.2H.sub.4 separation at lower costs.
