Indu-Diesel and Bio-Diesel as Renewable Fuel Synthesis from Used Automotive and Frying Oils

Abstract

Generally, the types of used oil by human to meet its necessary requirements regardless of its source, whether industrial or vegetarian or animal are considered as one of environmental contaminants which ceaseless due to continue consumption and continuation put forward of it in huge amounts by a large proportion of population in cities and rural areas. Automotive engines need to replace their lubricating oil after passing a distance reach to (1000 – 1500) km to ensure the safety and not affected the car engine leading to poses not inconsiderable oil quantity of industrial origin to environment, if accounting the number of cars and the amount of replaced oil by each car engine after commuting the aforementioned distance. Human need to an almost daily basis for frying the food which is eating it during the three daily meals leaving great amounts of agricultural or animal origin oils due to the large number of population. Both types form contamination because it contains a harmful or undesirable materials for human and environment together, especially if throw these oils directly without treatment. This research tackles the ability of producing two types of diesel fuels, the first one is indu-diesel which prepared from used automotive oils (UAO) and the second type is bio-diesel that synthesis from used frying oil (UFO) using concentrated sulfuric acid and thermal treated eggshell for two types of produced diesel fuel (PDF), then complete the production process by applied clay treatment with faujasite type Y-zeolite for indu-diesel from UAO and ethanol for bio-diesel from UFO and after that all required test were performed for two types and compared the results with ordinary diesel of fossil fuel origin. The results show that convergence in values of tests for both types of PDFs with ordinary diesel with a relative vantage for indu-diesel on bio-diesel. Thus, obtained a petroleum product (diesel) which can be used directly as fuel or mixing with ordinary diesel from one side, and from another side it can get-rid of UAO and UFO by economic, benefit, useful and eco-friendly method.
