| Summary: | The purpose of this work is the development of the use of lands from the bleaching stage and reincorporate it in the best way in the process. In order to do so, the current state of the palm oil refining process is diagnosed and the physical and chemical characterization of the raw, bleached, deodorized palm and the physical and chemical characterization of the pure lands and spent lands are carried out. Based on some authors consulted, two treatments of spent lands are selected and the alternatives are determined according to the yields evaluated by the authors. In the first treatment, extraction is validated with hexane and subsequent autoclave at 1.3 bar and 121 ° C, a medium yield is evidenced and the second treatment, extraction with acetone and subsequent calcination at 550 ° C for 90 minutes, equivalent to a good performance in the process compared to the standard palm oil refining process. The evaluation of the RBD palm on a pilot scale is developed with the selected treatment lands (acetone and subsequent calcination), varying the concentrations between pure lands and regenerated lands (0% and 0.8%, 0.4% and 0.6). %, 0.4% and 0.4%, respectively), the trial that obtained the best results, is replacing the regenerated lands with the pure lands (0% pure land and 0.8% regenerated land), when mixing regenerated lands with Pure land causes an incorrect incorporation of the type of bleaching earth, which generates unfavorable effects, fixes the color to a dark shade of RBD palm oil, promotes oxidation of primary and secondary groups because they were not adsorbed by the incorporated lands and generates undesirable reactions in the bleaching process. |
