Study on the Decoloration Technology of Waste Edible Oil with Activated Clay
Given more efficient utilization of waste, the social impact of waste recycling is far-reaching in saving resources and reducing environmental pollution, therefore promoting society development. The sources of waste edible oil are very complicated. The color of waste oil after simple recycling and refining is still dark and with strong smell. The amount of a variety of impurities is relatively huge. The pigment in waste oil affects its stability, industrial use and further processing. In order to meet the requirements of comprehensive utilization of waste oil, pre-decoloration is absolutely necessary. Activate clay has been reported to have decoloration effect on waste edible oil and this paper discussed the factors which influenced the decoloration rate. The optimum conditions of decoloration were established in this research: concentration of activated clay was 5％; initial temperature of decoloration was 60 ℃ ; final temperature of decoloration was 120℃ and time of decoloration was 25min. This result of research could provide appropriate material for the utilization of waste edible oil in production of detergent by saponification, save the natural resources and economy cost. At the same time, the waste became available resources.
