Adsorbent particles preparation method and treatment of soils polluted by hydrocarbons using said particles

   
   

The present invention relates to a method of preparing adsorbent particles formed from expanded plastics materials, said particles comprising cellular structures that are open at their surface, characterized in that a material constituted by agglomerated beads of said expanded material and having smooth surfaces is rasped into fine chips. The present invention also relates to adsorbent particles formed from an expanded plastics material comprising cellular structures that are open at their surface, characterized in that they are in the form of fine chips, preferably with a dimension of 0.8 mm to 4 mm, said open cellular structures represent more than 80% of the visible surface area of said chips. In a method of treating soil polluted with hydrocarbons, the following steps are carried out, in which: 1) said polluted soil is mixed with adsorbent particles according to the invention; and 2) said adsorbent particles charged with hydrocarbons are separated from the depolluted soil.

A invenção atual relaciona-se a um método de preparar as partículas do adsorbent dadas forma dos materiais de plásticos expandidos, partículas ditas que compreendem as estruturas celulares que estão abertas em sua superfície, caracterizadas que um material constituído por grânulos aglomerados de material expandido dito e de ter superfícies lisas rasped em microplaquetas finas. A invenção atual relaciona-se também às partículas do adsorbent dadas forma de um material de plásticos expandido que compreende as estruturas celulares que estão abertas em sua superfície, caracterizadas que estão no formulário de microplaquetas finas, preferivelmente com uma dimensão de 0.8 milímetro a 4 milímetros, estruturas celulares abertas ditas representa mais de 80% da área de superfície visível de microplaquetas ditas. Em um método de tratar o solo polluted com os hidrocarbonetos, as seguintes etapas são realizadas, em que: 1) o solo polluted dito é misturado com as partículas do adsorbent de acordo com a invenção; e 2) as partículas ditas do adsorbent carregaram com os hidrocarbonetos são separadas do depolluted o solo.
