Abstract
Official abstract text for this publication.
The present disclosure is directed to a desulphurization agent for removing sulphurous species from a diluent or process stream, and a use of such agent. In some examples, the agent may include a compound of manganese, pore forming particles and a compound of copper. The agent may be introduced into or mixed with the diluent or process stream to effectuate removal of sulphurous species from the diluent or process stream.
First claim
Opening claim text (preview).
The invention claimed is: 1. A desulphurisation agent, comprising: pore forming particles; at least one compound of manganese; and at least one compound of copper. 2. The agent of claim 1 , further comprising: at least one of a compound of iron and a compound of zinc. 3. The agent of claim 1 , wherein a ratio of the compound of manganese to the compound of copper is between 8:1 and 1:8 by weight. 4. The agent of claim 1 , wherein a ratio of the compound of manganese to the compound of copper is between 3:1 and 1:3 by weight. 5. The agent of claim 2 , wherein a ratio of the compound of manganese to the compound of iron is between 8:1 and 1:8 by weight. 6. The agent of claim 2 , wherein a ratio of the compound of manganese to the compound of iron is between 3:1 and 1:3 by weight. 7. The agent of claim 2 , wherein a ratio of the compound of manganese to the compound of zinc is between 8:1 and 1:8 by weight. 8. The agent of claim 2 , wherein a ratio of the compound of manganese to the compound of zinc is between 3:1 and 1:3 by weight. 9. The agent of claim 1 , wherein the pore forming particles comprise at least one of thermoplastic particles and thermoplastic spheres. 10. The agent of claim 1 , wherein the pore forming particles comprise hollow particles. 11. The agent of claim 1 , where in the pore forming particles comprise at least one of spheres, extrudates, granules, and tablets. 12. The agent of claim 1 , wherein pore forming particles comprise between 5% and 95% of a total volume of the agent. 13. The agent of claim 1 , wherein pore forming particles comprise between 10% and 30% of a total volume of the agent. 14. The agent of claim 1 , wherein the compound of manganese comprises at least one of an oxide, a hydroxide, and a carbonate. 15. The agent of claim 1 , wherein the compound of copper comprises at least one of an oxide, a hydroxide, and a carbonate. 16. The agent of claim 2 , wherein the compound of iron comprises at least one of an oxide, a hydroxide, and a carbonate. 17. The agent of claim 2 , wherein the compound of zinc comprises at least one of an oxide, a hydroxide, and a carbonate.
