TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The molecular sieve is a silica alumina phosphate, where the silica alumina phosphate is SAPO 34 (silicoaluminophosphate zeolite with 8-membered ring windows). The crystal size distribution of the SAPO 34 is 10080 mu , where the average crystal size of the SAPO 34 is 40 mu .    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The molecular sieve has an average pore size greater than 3.7 Angstrom . The adsorbent structure is characterized by a macroporosity of 4-18%. The adsorbent structure is characterized by a macropore size of 0.001-2 mu . The adsorbent structure is a parallel passage structured adsorbent comprising a laminated adsorbent sheet. The rapid cycle kinetic pressure swing adsorption apparatus is a rotary rapid cycle kinetic pressure swing adsorption apparatus.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: Preferred Process:: In the process: the product step time is determined to be longer than 50% of the time required for carbon dioxide to reach total equilibrium on adsorption sites, or the product step time is determined to be shorter than 10% of the time required for methane to reach total equilibrium on adsorption sites; and the evacuation step time is determined to be longer than 90% of the time required for carbon dioxide to reach total equilibrium on adsorption sites. The ratio of the time spent in the production step to that spent in the evacuation step is less than 0.15. The ratio of the time spent in a single equalization step to that spent in the production step is less than 0.25. In the process co-current depressurization steps are applied to generate reflux 1 recycle streams, where co-current depressurization steps are vacuum assisted to generate reflux 2 recycle streams. In the process a portion of exhaust gas is used as a co-current purge stream to recover remaining methane into reflux and/or recycle streams. The process further comprises exposing the sensitive adsorbent to water vapor before preparing the slurry, and then slowly adding water to the adsorbent before preparing the slurry. The first drying stage comprises: using a drying rate that removes less than or equal to 30 wt.% of water/minute; drying at less than or equal to 40 degrees C on exit of dryer; and removing 25-30 % of the water in the coated substrate before drying is discontinued. The second drying stage comprises using a drying rate that removes less than or equal to 5 wt.% of water/day; drying at ambient temperature; removing 5-10 % of the water in the coated substrate before drying is discontinued. The third drying stage comprises: using a drying rate that removes greater than or equal to 10 wt.% of water/minute; drying at above 130 degrees C; removing 5-10% of the water in the coated substrate before drying is discontinued. In the process up to 10% of the water in coated substrate remains in the adsorbent structure after drying. In the process 20-30 wt.% water is adsorbed by the sensitive adsorbent. The exposing takes place over a period of 4-7 days. Preferred Components: The slurry comprises up to 50 wt.% of water. The water vapor is ambient humid air. The substrate is a sheet and the adsorbent structure is a laminated sheet. EXAMPLE - No suitable example given.
