Abstract
The present disclosure provides for a porous gas sorbent material with superior gravimetric working capacity and volumetric capacity, a gas storage system including a porous gas sorbent material of the present disclosure, methods of making the same, and method for storing a gas. The porous gas sorbent material includes a gas adsorbing material and a non-aqueous binder.
Claims15
A method of isolating methane from a biogas, the method comprising:
- contacting biogas with a porous gas sorbent material having:
- <about 100 cc/L volume in pores smaller than about 9 Å size;
- >about 200 cc/L volume in pores about 9-27 Å size;
- and
- >about 50 cc/L volume in pores about 27-490 Å size, wherein the porous gas sorbent material isolates methane from the biogas.
2 more elements
A methane storage and release system comprising:
- a container having a gas inlet for receiving a gas stream comprising methane, and an outlet for delivering desorbed methane;
- and
- a porous gas sorbent material disposed therein, wherein the porous gas sorbent material includes:
- <about 100 cc/L volume in pores smaller than about 9 Å size;
- >about 200 cc/L volume in pores about 9-27 Å size;
- and
- >about 50 cc/L volume in pores about 27-490 Å size, wherein the porous gas sorbent material reversibly adsorbs methane from the gas stream.
