Poly (aniline-co-2-methoxy aniline-5-sulfonic acid) (PAMAS) was synthesized by an oxidative polymerization in this paper. The resulted copolymer was characterized by Fourier transform infrared spectroscopy and UV-vis spectroscopy, respectively. The PAMAS fibrous membranes and PAMAS/PEO fibrous membranes were prepared via electrospinning. The influence of the molecular weight of PEO and the ratio of PAMAS/PEO in spinning solution on the fibrous morphology was studied. The results showed that PAMAS has fiber-forming ability separately. The addition of PEO was helpful to the the electrospinning of PAMAS. With the increasing of PEO’s molecular weight, the average diameter of the PAMAS/PEO fibers increased. With the increasing of PAMAS content, the fibrous average diameter has an increasing tendency.

In this paper, we developed an effective method for purifying oil sludge using a sorbing electrochemical matrix and assessed the prospects of this method in comparison with conventional hydrocracking. We synthesized Ni-W supported hydrocracking catalysts with different morphology and studied their activity under various conditions, we compared the obtained catalysts with commercial catalyst SGK-5. We demonstrated that the introduction of a secondary mesoporous structure in the catalyst leads to an increase in the yield of light fractions to 52 wt.%. The possibility is demonstrated to obtain hydrocarbons from reservoir oil sludge, dispersed into an aqueous solution of detergent, by the method of low-temperature hydrogenation in sorbing electrochemical matrices. The obtained product was characterized by low viscosity, low content of transition metals (<320 ppm), and sulphur (<260 ppm).
