66-4 FIELD Section Title:Surface Chemistry and Colloids Research Institute of Petroleum Processing, SINOPEC, Beijing, Peop. Rep. China. FIELD URL: written in EnglishIn this paper, a new delaminated mesoporous material was prepd. by swelling the lamellar phyllosilicate Magadiite using cetyltrimethylammonium bromide and tetrapropylammonium hydroxide soln., followed by delamination under the cavitation of ultrasonic treatment. Various characterization tools including XRD, N2 adsorption, NMR, IR, SEM and TEM were employed to observe its structure and morphol. XRD results show that the delaminated material has no long-range cryst. order. Furthermore, not only high surface area is obtained, but almost half of it is external surface. The observation for the morphol. further reveals that it is made up of the random stacking of single or few layers. All these characters show that this delaminated mesoporous material meets the requirements for application as support in the hydrotreatment of heavy mols. [on SciFinder(R)

The new petroleum coke slurry fuel supply system was adopted in a R180 diesel engine, which was modified into the engine fueled with petroleum coke slurry. An investigation was carried out in the modified engine fueled with petroleum coke slurry. The engine fueled with 30 wt.% petroleum coke slurry could run steadily. The comparison test to velocity characteristic between engine fueled with 30 wt.% petroleum coke slurry and engine fueled with No. 0 diesel fuel was performed at full load running condition and at partial load running condition(75% load and 50% load). The test result showed that when burning petroleum coke slurry the specific fuel consumption was increased compared with that when burning diesel fuel. The brake torque and the brake power of the engine fueled with petroleum coke slurry were decreased compared with the engine fueled with diesel fuel, and the exhaust temperature of the engine fueled with petroleum coke slurry was similar to that of the engine fueled with diesel fuel.

Metal ions were implanted into the surface of fiber with metal vapor vacuum arc source implanter. The resin matrix composite was made of the surface modified fibers. The microwave absorbing property of the composite was measured. It is shown that the microwave absorbing property of the composite was improved effectively by the ion implantation and the extreme reflectivity reached -6.13dB. The paper studied the microwave absorbing property of the composite material treated by ion impregnation and discussed mechanism.
