The catalysts prepared on (poly)dopamine (Pdop) coated silica showed enhanced activity for the hydrogenation of toluene reaction and the selective HDS of FCC gasoline model feed. Pdop coating lowers the MoS2 nanocrystallites' stacking on silica, thereby improving the accessibility of active edge ...

In fact, E10 fuel absorbs some water, which can be positive unless it saturates and a layer of water and ethanol begins to form on the bottom of the tank. However, there would be lower octane and no ethanol in the gasoline in the layer above. There is no realistic way of stabilizing ...
Before then, despite overwhelming medical science, lead was added to gasoline. A mass of studies has found that HIGH levels of lead in the blood of fetus and children results in lowered intelligence, behavioral problems, etc. And studies have found some post-war chemi...
At some stations, it’s 93 octane, and can be even higher. As with using mid-grade gas to quell knock, premium may work if mid-grade doesn’t quite do the trick. The best place to find what gasoline should be used in your car is in the owner’s manual; look under “Fuel” in...
