The researches on Kazakhstan oil-wet oil sand were carried out by the solvent extraction method, from which the best solvent was found out. The influences of oil sand particle, the weight ratio of oil sand, the solvent type, and the extraction time of the oil yield were discussed in the experiment. When naphtha was chose as the solvent with the oil sand size blow 40 mesh, the ratio of solvent and oil sand fixed at about 4∶1, and the reaction time about 10 min at room temperate. The recovery yield of oil from oil sand is above 98%. The experiment is instructive to oil-wet oil sand separation.

The weight percentage of Fe2+ can be determined with 1,10-phenanthroline as chromogenic agent, and Fe2+ would be oxidized by bromate to Fe3+ and then 1,10-phenanthroline faded. Therefore, the content of bromate in water can be indirectly determined according to the stoichiometry amount of Fe2+. The linear range, detection limit, recovery, chromogenic conditions were studied and found that the recovery is 92.5%~108.7%, detection limit is 15~36 ng/L, the precision is less than 0.312.

Taking crude oil from Inner Mongolia oil sands as an example, dehydration by adding demulsifier and heating settlement combined methods are used to study the optimum operation conditions. The results show that water can be effective removed from the oil-sands oil at 90 ℃ for 5 h, and the water content can be reduced to 1%.

MTBE (methyl tert-butyl ether), is an additive with high octane number (RON118, MON101), low vapor pressure and similar calorific value with the hydrocarbon, it can be with methanol gasoline miscible in any proportion and can increase the tolerance on water and layered ability of methanol gasoline. According to vehicle M15 methanol gasoline local standard, the influence of methanol and MTBE dosages on vehicle gasoline properties was studied to blend new M15 vehicle methanol gasoline which can reach the requirements of automobile engine usability. The results show that when the addition of MTBE is 50%, water tolerance of M15 is about 3.0%, and 1.5% water content of M15 is not layered in condition of -38 ℃.

The oxidation of vacuum residue of Russian fuel oil M100 was studied with self-made device for 10 h under the oxidation temperatures 225 and 250 ℃ with the ventilation capacity of 0.2 m3/(h•kg). The results show that three asphalt of oxidized samples can meet well with technical requirements of road asphalt (JTG F40-2004) for 130#C, the standard grade of asphalt and bitumen and 110#C grade standards. A modifier SBS was added with the weight ratio of 1% to 5%, and the MAW-1-type stabilizer was also added with the mass ratio of stabilizers to SBS 1∶(10~15). Two polymer modified bitumen were in line with the standard of the SBS class I-A in the technical requirements (JTG F40-2004).

A high efficient decalcification agent without phosphorus or metal included was developed for Liaohe crude oil with high calcium content. The calcium contents in the crude oil before and after decalcification were analyzed by atomic absorption spectrometry. Influences of decalcification agent to calcium radio, water injection amount, working temperature, time for sedimentation and reaction were studied. The results show that when the decalcification agent dosage is 0.6, filling water ratio is 10%, reaction temperature is 90 ℃,the time for settlement is 10 h and reacting time is 5 min, the decalcification rate of Liaohe crude can reach more than 90%.
