Composite materials and methods of preparing C0.sub.2 capture include: (1) a porous solid support comprising a plurality of porous channels; and (2) a nucleophilic source associated with the porous channels of the porous solid support. The nucleophilic source is capable of converting the captured C0.sub.2 to poly(C0.sub.2). Methods of capturing C0.sub.2 from an environment include associating the environment with the aforementioned composite materials to lead to the capture of C0.sub.2 from the environment. Such methods may also include a step of releasing the captured C0.sub.2 from the composite material. The associating step comprises a conversion of the captured C0.sub.2 to poly(C0.sub.2) in the composite material. A releasing step may also include a depolymerization of the formed poly(C0.sub.2).

The present invention relates to a method of separating and recovering NGLs from a natural gas feedstream. Specifically, the present method allows for the separation of ethane and heavier hydrocarbons and/or propane and heavier hydrocarbons from a raw natural gas feedstream to provide pipeline quality natural gas. One embodiment of this method provides for the use of a regenerable adsorbent media which is regenerated by a microwave heating system. Said regeneration step may be operated as a batch process, a semi-continuous process, or a continuous process.

Methods of forming a high surface area compacted MOF powder are disclosed, as well as MOF pellets formed thereby. The method may include synthesizing a metal organic framework (MOF) powder using a first solvent, exchanging the first solvent with a second solvent such that pores of the MOF powder are at least 10% filled with the second solvent, compacting the MOF powder having pores at least 10% filled with the second solvent into a pellet, and desolvating the compacted pellet to remove the second solvent. The pellet may maintain a specific surface area after compacting that is at least 80% its initial specific surface area. Compacting the MOF powder with a solvent at least partially filling its pores may prevent or reduce crushing of the MOF pore structure and maintain surface area, for example, for hydrogen or natural gas storage.
