Abstract
A method for separating gases or other fluids involves placing a magnetic field on a monolithic carbon fiber composite sorption material to more preferentially attract certain gases or other fluids to the sorption material to which a magnetic field is applied. This technique may be combined with the known "pressure swing adsorption" technique utilizing the same sorption material.
Claims4
A sorption method for separating a mixture of fluids into a first fluid which has a magnetic susceptibility and which is more preferentially sorbed and a component fluid which has a lesser magnetic susceptibility than the first fluid and which is less preferentially sorbed comprising the steps of:
- (A) Providing a sorption material comprising an activated carbon fiber composite material further comprising a multiplicity of porous carbon fibers bonded with a carbonizable organic binder to form an open, permeable structure and having enhanced sorption affinity for said first fluid in the presence of a magnetic field;
- (B) Subjecting the sorption material to a magnetic field while
- (C) Contacting the mixture of fluids with the sorption material wherein the magnetic field operates to cause the first fluid to be preferentially diffused to the sorption material so that the first fluid is sorbed at a faster rate than the component fluid;
- and
- (D) Eluting that component fluid which was less preferentially sorbed from contact with the sorption material.
Apparatus for separating a mixture of fluids into a first fluid having a magnetic susceptibility which is more preferentially sorbed and a component fluid having a lesser magnetic susceptibility than the first fluid and which is less preferentially sorbed comprising:
- (A) A sorption chamber having an inlet and an outlet;
- (B) Sorption material contained within the sorption chamber, said sorption material comprising an activated carbon fiber composite material further comprising a multiplicity of porous carbon fibers bonded with a carbonizable organic binder to form an open, permeable structure and having enhanced sorption affinity for said first fluid in the presence of a magnetic field;
- (C) Means for subjecting the sorption material to a magnetic field;
- (D) Means for contacting the mixture of fluids with the sorption material wherein the magnetic field operates so that the first fluid is preferentially diffused to the sorption material and the first fluid is sorbed at a faster rate;
- and
- (E) Means for eluting that component fluid which was less preferentially sorbed from contact with the sorption material.
