  • the petroleum hydrocarbon lubricating base oil which is produced in the final step of the common crude oil refining process, is generally used as base oil for grease.
  • grease using the petroleum hydrocarbon may cause environmental damage, and may threaten the health of a human who uses the grease.
  • the present invention is directed to developing a grease composition using a distillation residue generated in the production of biodiesel as environmentally friendly lubricating base oil.
  • Biodiesel refers to an alternative energy processed from elemental lipid in vegetables and animals to have similar properties to gasoline, which can be used as a diesel equivalent or for diesel engines by being mixed with the gasoline.
  • biodiesel refers to fatty acid methyl esters having a purity of 95% made from the transesterification between alcohols (generally, methanol) and vegetable oil (rice bran, waste cooking oil, soybean oil, rape oil, etc.). (Ministry of Commerce, Industry and Economy (MOCIE) Announcement No. 2000-57)
  • the vegetable oil described above that is, a compound including a hydrophobic group insoluble in water, is generally composed of triglycerides represented as the following chemical structural formula.
  • the vegetable oil is commonly characterized by the content of the fatty acid, and the length, content and saturation degree of the fatty acid become critical factors in determining physical and chemical characteristics of the oil.
  • Animal oil is less useful than the vegetable oil, and only that made from a pig, a cow and a sheep among land animals, and herring and menhaden among fishes are considered as being commercially important.
  • the animal oils are composed of saturated and unsaturated triglycerides like the vegetable oils, but include a wide distribution of fatty acids and some odd-numbered chain fatty acids, unlike the vegetable oils.
  • the methyl ester from vegetable oil is mainly made of methyl oleate and methyl linoleate as main components, and exhibits excellent performance in machinability or detergency due to low viscosity (40°C, 1.9 to 6.0 cSt.) and good lubrication when used instead of petroleum-based hydrocarbon lubricating base oil.
  • the methyl ester from vegetable oil is made by the following processes.
  • R, R' and R" are saturated or unsaturated hydrocarbons with alkyl groups.
  • Components and ratios of vegetable oil methyl ester depend on components and composition ratios of fatty acid of the vegetable oil.

  • biodiesel is in exemplary use or is expanding its supply through model projects all over the world. Europe, which is very positive towards the use of alternative energy, first established a system for biodiesel.
  • biodiesel can be used within a range satisfying the standard of general gasoline, and according to European Fuel Standard (EN590) taken effect in January, 2004, gasoline including 5% biodiesel or less (BD5) is recognized as general gasoline (satisfying the requirements of the EN14214 standard).
  • EN590 European Fuel Standard

  • U.S. after National Biodiesel Board was founded in 1992, the Congress and EPA approved BD20 as a fuel for diesel engine vehicles in 1998, and President Bush declared the expansion of new recycled energy including biodiesel in 2001.
  • the supply of biodiesel is increasing every year, and biodiesel is used in official vehicles of state governments and buses in addition to the U.S. Army, the U.S. Air Force, the Department of Energy and NASA.
  • biodiesel In Korea, based on the announcement regarding a model supply project for biodiesel by MOCCC in May, 2002, the government performed the project for two years, and now is investigating market reaction to and problems with biodiesel.
  • the major advantage of biodiesel is a reduction of smoke emitted from vehicles.
  • biodiesel also emits the greenhouse gas CO 2 , when viewed from an overall cycle of the process (from production to consumption) it yields very low amounts of CO 2 , and emits relatively low amounts of sulfur oxide (Sox) and particulate matters (PMs).
  • Biodiesel made from vegetable resources may be self-produced domestically, which is an advantage for energy security, and may reduce environmental pollution by recycling waste resources, such as waste cooking oil.
  • biodiesel has several problems in substituting for conventional gasoline and volatile oils. Although biodiesel has to be mixed in a high ratio to reduce toxic chemicals in exhaust gases from vehicles, it may break down engines due to corrosion, and become denatured in long-term storage.
  • methyl esters made from vegetable oil are required for methyl esters made from vegetable oil to be used as fuel oils for vehicles, and thus a separate vacuum distillation process is performed after the reaction of methyl esters.
  • the vacuum distillation is performed at 2 to 3 torrs and a maximum temperature of 240°C.
  • the distilled result is used as biodiesel fuel oil, and a distillation residue of about 10% is scrapped.
