Title: Purificn. and re-use of expanded graphite - used to absorb hydrocarbons, by distn., extn. or burning-off
Inventor: BITZER DIETHELM DIPL CHEM DR
IPC: C02F1/68
Filed: 1975-09-12
Abstract: Expanded graphite used to absorb oil, petrol, liquid hydrocarbons and hydropholic chemicals e.g. from the surface of water, is purified by distn., extraction or burning-off of the absorbed liq. Pref. density of the expanded graphite is 0.002-1.7, and it is used as an aq. dispersion in concn. of 0.001-5% for compression into oil-bearing strata to extract residual oil. The dispersion pref. also contains up to 5 wt.%, pref. 0.001-1% polyacrylamide to prevent deposition of graphite in the strata. Cost of the expanded graphite is reduced, together with transport costs, and the graphite is left in its original condition. Since no water is absorbed, the liquid hydrocarbons can be quickly and completely burnt off. In an example 15 g ligroin on the surface of water is immediately absorbed by 1.5 g expanded graphite. After skimming off the graphite contg. ligroin, it is burnt on a sieve, through which the purified graphite falls.
