The invention discloses a hydrogenation method for treating high-nitrogen high-aromatic hydrocarbon inferior diesel oil raw materials. An integrated two-section process flow of a first reaction area, intermediate separation and a second reaction area is adopted. The method comprises the following steps: performing hydrodenitrogeneration and bicyclo- or multi-cyclo aromatic hydrocarbon hydrogenation saturation reactions on inferior diesel oil with high nitrogen and aromatic hydrocarbon content in the first reaction area, performing intermediate separation, obtaining a hydrogenated material flow in which the organic nitrogen content is less than 200 ug/g and the total aromatic hydrocarbon content is more than 60 weight percent, and providing the raw materials for the second reaction area; performing moderate refining and hydro-upgrading in the second reaction area, and performing fractionation to obtain gasoline components with high octane value. By adoption of the method provided in the invention, the inferior diesel oil fraction with high nitrogen and aromatic hydrocarbon content can be treated, and the gasoline components with high octane value and low sulfur content are obtained at high yield.

The invention discloses a combined process for pretreating and catalytically cracking hydrocarbon oil. The process comprises the following steps of: feeding a residual oil raw material and catalytic cracking slurry oil into a solvent de-asphalting device for performing de-asphalting treatment; mixing de-asphalted oil with deep drawing VGO (Vacuum Gas Oil), feeding into a hydrogenation demetalization reaction area, and undergoing a reaction under the actions of hydrogen and a demetalization catalyst; mixing one or two of obtained hydrogenation demetalization effluent, light wax oil and coking gas oil, feeding into a hydrotreatment reaction area, and undergoing a reaction in the presence of hydrogen and a hydrotreatment catalyst, wherein a liquid phase separated from hydrotreatment reactor effluent is taken as a catalytic cracking raw material; and feeding the catalytic cracking raw material into a catalytic cracking device for reacting, and circularly returning the catalytic cracking slurry oil to the solvent de-asphalting device for performing circular processing. Due to the adoption of a method disclosed by the invention, different catalytic cracking raw materials can be treated segmentally, the operating flexibility and desulfuration efficiency of a device are increased, and the cost is lowered.

The invention belongs to the technical field of agricultural machinery, particularly relates to a corn ear chopping and kernel crushing device as well as a working method and an application thereof, and discloses a corn ear smashing device capable of completing corn ear feeding, corn ear chopping, kernel crushing and material throwing. After corn ears are fed into the smashing device, the ears arechopped through the interaction of a movable cutter and a fixed cutter of a chopping device, chopped ear materials pass through kernel crushing rollers rotating oppositely, corn kernels are smashed into 1/3-grain to 1/4-grain, then the materials are conveyed to one side under the action of a conveying auger and thrown out through a throwing device and a throwing barrel, the ear smashing quality can be effectively improved, and high-quality feed is provided for the animal husbandry.

The invention relates to a method for treating green plum fruit wine vinasse residues and liquor. The method comprises the following steps that firstly, the green plum fruit wine vinasse residues and liquor are recycled in a settling basin, and the pH value of the green plum fruit wine vinasse residues and liquor is measured; secondly, alkali or alkaline matter is added in the settling basin in the first step to regulate the pH value of the green plum fruit wine vinasse residues and liquor to be 6-9; thirdly, destabilizing and settling accelerating agents polyaluminum chloride or/and polyferric sulfate are added with the adding quantity of the desertion stabilizing and settling accelerating agents accounts for 0.0015-0.003% of the plum fruit wine vinasse residues and liquor, and the mixture is evenly stirred and then subjected to standing; fourthly, water liquid on the middle and upper layers is drained; fifthly, bottom layer sediment obtained in the third step is dehydrated; sixthly, the dehydrated sediment is dried and ground, and an end vinasse powder product is obtained.
