| 其它 | Hydrocracking spent catalyst is a hazardous residue produced in large quantities in petroleum refining industries, it contains non metals or metals which are important components for advanced material. Leaching is a hydrometallurgical process which is an effective technology for metal extraction from low grade metal sources with appropriate solvent, low processing cost and relatively low pollutant. The waluable metals extraction was conducted using both organic and anorganic acids. Temperature (90 ̊C) and pH (1,5, 2) were varied to observed the performance of both acid with solid ratio of 1:20 in the atmosphere condition. Sample were analice using x-ray flourescence (XRF) before exraction and after extraction. From the result, it can be conducted which citric acid process ability to extract valuable metals as high as organic acid |
