The Re-refining of Used Lubricating Oils
Re-refined lubricants have been produced in New Zealand for over 50 years. However, their acceptance as a high quality lubricant has been a gradual process, largely because of the scepticism of the public that the product can be re-refined to its original condition. In New Zealand Dominion Oil rerefines about 7 million litres per year, while an older acid clay method is used at Turua near Thame...
متن کاملLubricating gears with synthetic OiLs
wind gearbOx technOLOgy is developing at a fast pace, not least due to operators demanding ever more power and efficiency. Experience has shown that the lubricant used is a crucial factor in meeting the wish for ever-increasing performance. Besides strictly technical requirements, aspects of economy and ecology are receiving more and more attention in lubricant selection. The technical requirem...
متن کاملEco-Friendly Multipurpose Lubricating Greases from Vegetable Residual Oils
Environmentally friendly multipurpose grease formulation has been synthesized by using Jatropha vegetable residual oil with lithium soap and multifunctional additive. The thus obtained formulation was evaluated for its tribological performance on a four-ball tribo-tester. The anti-friction and anti-wear performance characteristics were evaluated using standard test methods. The biodegradability...

اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
Two insulation oils from highly-refined mineral-base oils induced transformation of Syrian hamster embryo cells and enhanced transformation of mouse C3H lOTlj2 cells. Unused new, re-refined and used crankcase oils induced transformation in Syrian hamster
when the concentration of the exogenous metabolic system was five to ten fold that used generally. Acid-treated oils were not mutagenic to S. typhimurium in the presence of an exogenous metabolic system; solvent-refined oils were reported to be mutagenic in the presence of an exogenous metabolic system. Hydrotreated oil was reported to be mutagenic to S. typhimurium in the presence of an exogen...
