Abstract
Adsorbents for removing contaminants from hydrocarbon streams are described. The adsorbents comprise polyurethane foam comprising a metal compound. The polyurethane foam can be rigid or flexible and has a structure comprising a combination of open cells and closed cells. Methods of removing contaminants from hydrocarbon streams using the adsorbent are also described.
Claims20
An adsorbent for removing a contaminant from a hydrocarbon stream comprising:
- polyurethane foam comprising a metal compound, wherein the polyurethane foam comprises 5% to 95% closed cells.
A method of removing a contaminant from a hydrocarbon stream comprising:
- contacting the hydrocarbon stream with an adsorbent comprising a polyurethane foam comprising a metal compound, wherein the polyurethane foam comprises 5% to 95% closed cells.
A method of making an adsorbent for removing a contaminant from a hydrocarbon stream comprising:
- providing a polyol premix comprising a polyol, a metal compound, a catalyst, and a blowing agent;
- mixing the polyol premix with an isocyanate to form a mixture;
- pouring the mixture into a mold;
- and
- curing the mixture to form a polyurethane foam comprising 5% to 95% closed cells.
