In general, this disclosure describes method of capturing and storing CO.sub.2 on a vehicle. The method includes contacting an vehicle exhaust gas with one or more of a first metal organic framework (MOF) composition sufficient to separate CO.sub.2 from the exhaust gas, contacting the separated CO.sub.2 with one or more of a second MOF composition sufficient to store the CO.sub.2 and wherein the one or more first MOF composition comprises one or more SIFSIX-n-M MOF and wherein M is a metal and n is 2 or 3. Embodiments also describe an apparatus or system for capturing and storing CO.sub.2onboard a vehicle.

A sieve seal as a component embodied of one piece, consisting of a seal, which holds a sieve body so that it is enclosed over an inner free cross-sectional area. The present invention also relates to a method for sustained operation of a sieve seal of this kind. In order to provide a remedy in the event of a clogging and/or soot formation and an accumulation of deposits in the sieve seal, it is proposed that the sieve body is embodied for an electric current to flow through at least part of it in such a way that a temperature that is sufficient to eliminate at least significant parts of the deposits is achieved or a corresponding temperature threshold is exceeded.

An object of the present invention is to provide a chabazite zeolite which does not easily peel from a substrate such as a honeycomb body even when the substrate has been coated therewith, while exhibiting excellent durability. The present invention relates to a chabazite zeolite for substrate coating, which includes (i) to (iv) below. (i) Si and Al are contained, (ii) an SiO.sub.2/Al.sub.2O.sub.3 molar ratio is in a range of 5<SiO.sub.2/Al.sub.2O.sub.3<10, (iii) an average crystal size is in a range of 0.05 m< average crystal size <1 m, and (iv) in a spectrum measured by .sup.27Al-NMR, a ratio (A.sub.NFA/A.sub.Total) between an area (A.sub.Total) of all peaks in the spectrum and an area (A.sub.NFA) of peaks assigned to Al other than tetracoordinated Al is in a range of 20%(A.sub.NFA/A.sub.Total)70%.
