Abstract
A method for enhancing sorption performance of a sorbent material includes the step of increasing a surface area of the sorbent material for adsorption of a fluid at an interface between the fluid and the sorbent material by arranging one or more apertures to be disposed on the sorbent material, wherein each of the one or more apertures is further arranged to define an interior space for absorption of the fluid.
Claims10
A liquid sorbent comprising:
- a body having a homogenous structure;
- and
- a plurality of apertures cut or drilled on the body, the plurality of apertures penetrating one-third to half of a thickness of the liquid sorbent and defining an interior space for absorption and adsorption of a liquid with a viscosity of 350 to 1200 mPa·s;
- wherein the liquid sorbent has a surface area to volume ratio of 1.3 cm−1 to 2.5 cm−1;
- wherein each of the plurality of apertures has a cross sectional area of 78.5 mm2 to 283 mm2;
- and
- wherein the plurality of apertures are disposed on the body of the liquid sorbent with a distribution density of 0.003 to 0.5 apertures per square centimeter.
