Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
113 words
AN ACTIVE SORBENT COMPRISING READILY FLUIDIZABLE FILMED PARTICLES OF ACTIVATED, POROUS, SOLID CUPROUS HALIDE SORBENT HAVING AN AVERAGE PARTICLE SIZE RANGING FROM ABOUT 30 TO 200 MICRONS HAVING THEREON FROM ABOUT 0.5 TO ABOUT 30 WT. PERCENT BASED ON CUPROUS HALIDE OF A SOLID POROUS, CURED POLYMERIC FILM COMPRISED OF A POLYMER CURABLE BELOW APPROXIMATELY 200*F. WHEREIN THE PORES OF SAID FILM COMMUNICATE WITH THE PORES OF SAID ACTIVE CUPROUS HALIDE ALONG COMMON AXES OF POROSITY, SAID CURED POLYMERIC FILM HAVING AN AVERAGE THICKNESS RANGING FROM ABOUT 10 TO 600 A. AND THE RESISTANCE TO ATTRITION OF SAID FILMED PARTICLES BEING GREATER THAN THAT OF ACTIVE, SOLID, POROUS CUPROUS HALIDE PARTICLES, PER SE.
