    摘要： Provided are: a hydrocarbon adsorbent capable of adsorbing hydrocarbons, storing the adsorbed hydrocarbons up to a relatively high temperature, and desorbing the adsorbed and stored hydrocarbons at a relatively high temperature; an exhaust gas purifying catalyst composition using the same; an exhaust gas purifying catalyst; and a method for treating an exhaust gas. The hydrocarbon adsorbent comprises a zeolite having an MRT-type framework structure. The hydrocarbon adsorbent comprises a small-pore zeolite having a total desorption amount ZD1 of propylene desorbed at 50° C. or higher and lower than 300° C. being 3.5 mmol/g or less and a total desorption amount ZD2 of propylene desorbed at 300° C. or higher and 500° C. or lower being 0.5 mmol/g or more, per 1 g by mass of the small-pore zeolite, when adsorbing propylene at 50° C. and then heating from 50° C. to 500° C. under the condition of 10° C./min by a temperature-programmed desorption method.

    摘要： The present invention relates to a crystallised solid, called IZM-5, comprising a chemical composition expressed on an anhydrous base, in terms of mole, and defined by the following general formula: SnaZnbS8: cR, wherein R represents at least one nitrogenous organic species; S sulphur, “a” is the molar amount of tin, denoted Sn, between 0.1 and 5; “b” is the molar amount of zinc, denoted Zn, between 0.2 and 8; “c” is the molar amount of the nitrogenous organic species R between 0 and 4.

    摘要： The present disclosure relates to an RHO-type zeolite comprising caesium and M1 wherein M1 is selected from Na and/or Li remarkable in that it has a Si/Al molar ratio comprised between 1.2 and 3.0 as determined by 29Si magic angle spinning nuclear magnetic resonance, in that the RHO-type zeolite has a specific surface area comprised between 40 m2g−1 and 250 m2g−1 as determined by N2 adsorption measurements, in that the RHO-type zeolite being in the form of one or more nanoparticles with an average crystal size comprised between 10 nm and 400 nm as determined by scanning electron microscopy wherein said nanoparticles form monodispersed nanocrystals or form aggregates of nanocrystals having an average size ranging from 100 nm to 500 nm, as determined by scanning electron microscopy. Amorphous precursors, devoid of an organic structure-directing agent, as well as a method for preparation of these amorphous precursors in the absence of such organic structure-directing agent and method for preparation of the RHO-type zeolites, are alos described. Finally, the use of the RHO-type zeolite as a sorbent for carbon dioxide is also demonstrated.
