Abstract: Disclosed are a hydrogenation catalyst, a preparation method for same, and applications thereof. Also disclosed is a hydrogenation reaction method employing the hydrogenation catalyst. The hydrogenation catalyst of the present invention comprises a binding agent and an active component. The active component comprises nickel and a group VIB metal element. The binding agent comprises zirconium oxide and aluminum oxide. The catalyst of the present invention has nickel serving as the main active ingredient and is inexpensive. Moreover, the catalyst of the present invention exhibits an increased catalytic activity in a hydrogenation reaction of phenolic compounds and specifically provides an increased low-temperature reaction activity. The catalyst of the present invention is applicable in a continuous production process, thus implementing the continuous production of a hydrogenated bisphenol A product and providing the product with high and stable quality.

Abstract: The invention provides a suspension modifier directly added into fracturing fluid for real-time proppant modification during fracturing and the application thereof, relating to the field of oil and gas production technologies. The suspension modifier is a controlled release nanoemulsion and comprises surface hydrophobic modifier, surfactant, cosurfactant and water. The suspension modifier is directly added into clear-water or active-water fracturing fluid while the proppant is added into water. After stirring, the suspension modifier is capable of self-assembling and being adsorbed on the proppant surface, so that the proppant surface becomes hydrophobic and aerophilic. The invention no longer requires the proppant to be pretreated, and the bubble-suspended proppant can be obtained directly by adding the suspension modifier to the clear-water or active-water fracturing fluid, and meanwhile adding the proppant to the fracturing fluid.
