## Abstract

An adsorption web for adsorption of petrochemical substances from liquid phases or for adsorption of odorous substances has at least one face coated with a polymer. At least one adsorption substance present is in the polymer as a filler and has micropores or mesopores or macropores.

## Claims

### Claim 1

An adsorption web for adsorption of petrochemical substances from liquid phases or for adsorption of odorous substances, wherein at least one face of the web is coated with a polymer, with at least one adsorption substance present in the polymer as a filler and with said adsorption substance exhibiting micropores or mesopores or macropores.

### Claim 2 (depends on 1)

The adsorption web according to claim 1, wherein the polymer consists of synthetic rubber.

### Claim 3 (depends on 2)

The adsorption web according to claim 2, wherein waste materials from synthetic rubber production is used as synthetic rubber.

### Claim 4 (depends on 2)

The adsorption web according to claim 2, wherein the synthetic rubber consists of styrene butadiene rubber.

### Claim 5 (depends on 1)

The adsorption web according to claim 1, wherein the polymer is bonded to the web.

### Claim 6 (depends on 1)

The adsorption web according to claim 1, wherein the polymer exhibits a residual water content of 2 to 10 percent by weight.

### Claim 7 (depends on 1)

The adsorption web according to claim 1, wherein the adsorption substance has activated carbon, soot, zeolites, silicon compound, or petroleum coke.

### Claim 8 (depends on 1)

The adsorption web according to claim 1, further comprising:
at least one auxiliary agent in the polymer, a white pigment being the auxiliary agent.

### Claim 9 (depends on 1)

A method for producing an adsorption web according to claim 1, the method comprising the steps of:
coating a web on at least one face of the web with an aqueous polymer emulsion containing at least one porous adsorption substance as a filler; and
drying the web coated with the emulsion so that the polymer bonds with or adheres to the filler and the polymer is fixed on the web.

### Claim 10 (depends on 9)

Method according to claim 9, further comprising the step of:
covering the polymer-coated face of the web with at least one covering web; and
bonding the covering web to the web or polymer.
