| Summary: | Porous membranes are prepared through micro phase separation of immiscible polymers consisting of hydrophobic polymer (polystyrene) and hydrophilic polymer (poly(2-vinylpyridine)). The greatest difficulties during petrolatum deoiling are related to the filtration stage for obtaining microcrystalline wax. The present study deals with the addition of porous membrane as modifier for the crystal structure of solid hydrocarbons, which will be the cornerstone in rearrangement and reformulation of new hard crystals in deoiling process. XRD and SEM photographs were used to evaluate the crystallinity and crystal sizes of the separated hard waxes. |
