## Abstract

A method for producing a hydrocarbon absorber by extraction and processing of vegetable fibers from the Australian king palm (Archontophoenix cunninghamiana), discarded as waste by the agricultural industry and possessing a high hydrocarbon sorption and agglutination capacity in land environments.

## Claims

### Claim 1

A method for Obtaining Hydrocarbon Absorber and Product Obtained, comprising the following steps:
performing a withdrawal and transversal cut of a stem from an Australian king palm (Archontophoenix cunninghamiana), originating tablets of approximately 5 cm in thickness and various diameters having their moisture removed through environmental exposure; grinding dried pastilles in a hammer mill and dismembering them so that their fibers can be removed, and then drying, after dismembering, to form pellets, wherein the pellets originate two types of fibers, a finer type in powder form having a different size, and a long fiber type having a length of about 5 cm; then the two types of fiber have their moisture removed in circular dryer and/or sieve and then the two types of fiber are separated; after separation the powdered fiber is exposed to the sun so that its drying occurs and the powder becomes an absorber, which is packaged and stored.

### Claim 2 (depends on 1)

The method for Obtaining Hydrocarbon Absorber and Product Obtained, according to claim 1, wherein the absorber exhibits humidity up to 15%.

### Claim 3 (depends on 1)

The method for Obtaining Hydrocarbon Absorber and Product Obtained, according to claim 1, wherein the absorber exhibits absorption up to 5.8 times its mass.
