Description
Technical field
The present invention relates to silica decoloration sand technical field, the regeneration of especially a kind of oil product silica decoloration sand is prepared and its is answered
Use method.
Background technique
Oil product silica decoloration sand is white particle, and main component is silica, and oil product silica decoloration sand breaks tradition
Acid, alkali, carclazyte decolouring and deodorizing complicated technology, directly using filtering mode be filtered to remove impurity and oxide in oil product, collect
It cleans, de-taste, decolourize, be located away from one, the oil product of blackening is made to become the liquid of light-coloured transparent, make the acid of liquid oil body after processing
Value, coloration meet national fuel standard, and store that non-discolouring, stability is good for a long time, have greatly saved cost of investment, shorten
Process flow and time.
Obtained by silica decoloration sand is processed using silica gel as raw material, silica decoloration sand can use this body structure of silica gel
In a large amount of nanoscale molecular structural principle that contains, the absorption of the pigment and impurity in used oil or waste diesel can be carried out.Silicon
The oil product that glue decoloration sand washes out, slag yield are considerably less than the slag yield using Traditional Method washing oil；It is at low cost, it is widely applicable,
Silica decoloration sand can not only clean the small oil refining with crude refining, moreover it is possible to handle lubricating oil, reduce line oil, two wires oil, useless machine
The diesel oil of the refinings such as oil and the oil product that cannot be washed out with old method, applicable surface are quite extensive；It is saving of labor, time saving, laborsaving, significantly mention
