STORAGE STABILITY TESTS ON PETROL

FOA-PROV MED LAGRING AV BENSIN SPAR STORA PENGAR AAT FOERSVARET

Storage times for petrol are of great interest to the defence forces which store large quantities. Stocks used to be turned over after a few years, but this was very expensive, and investigations are being made to find if storage times can be extended. The aim is to store petrol for 20 years. Petrol contains actual and potential resins; the latter is formed due to oxidation, which can be accelerated in tests at elevated pressures and temperatures. Relationships are then established between events during these tests and under storage conditions. Petrols differ in their storage stability; by applying a least value of A constant in a formula relating to rate of reaction, storage stability can be predicted with reasonable accuracy. If A petrol contains 2-4 mg resin per 100 ml, it can be regarded good, while if the quantity of resin exceeds 10 mg, the petrol cannot be approved. Petrol stored at 20 degrees C will remain stable for a long time, while that kept at 40 degrees c decomposes in 18 months. It has been found that storage times can be increased from 5 to at least 10 years provided that periodical checks are made. /TRRL/
