Disclosed are a sorbent produced by recycling waste paper, which is an eco-friendly recycling paper resource, to adsorb and remove a marine spilled oil and other types of oil and a method of producing the same. The oil sorbent is produced by hydrophobizing a biomass material such as waste paper using a gas-grafting method. Compared to the oil sorbent of the prior art formed of synthetic resin, it is possible to provide excellent oil adsorption selectivity, a high oil adsorption rate, and a low water absorption rate. Therefore, an incineration process for processing the waste oil sorbent after use is easy advantageously. The oil sorbent generates less harmful substances during combustion because the eco-friendly material is used. Since a biomass material is hydrophobized using vegetable fatty acids, decomposition is performed fast within a short time in a landfill process, and there is no risk of environmental pollution.

A process of granulation of a urea melt, comprising: adding a first additive containing carboxymethyl starch to one or more first stage(s) of the granulation process, to form a carboxymethyl starch containing inner layer of urea granules, and adding a second additive containing calcium lignosulfonate to one or more second stage(s) of the granulation process, downstream said first stages, to form granules with a coating containing calcium lignosulfonate.

Hydrophobized granular material comprising from 30 to 95% by weight of a pyrogenic mixed oxide based on silica and at least one oxide of metal M selected from of Al, Ti and Fe with the content of metal M oxide in the mixed oxide being from 01 to 10% by weight, and from 5 to 70% by weight of at least one IR-opacifier selected from the group consisting of silicon carbide, zirconium dioxide, ilmenites, iron titanates, zirconium silicates, manganese oxides, graphites, carbon blacks and mixtures thereof.

A thermal extrusion method to fabricate large-dimension superhydrophobic cylinder pillar arrays with droplet pancake bouncing phenomenon. Preparing thermal extrusion mold: the through-hole arrays with 0.8˜1.25 mm diameter, 0.25 mm interval space and 0.6˜1.0 mm height are first obtained on metals, and are then polished, rinsed and dried. Thermal extrusion: polymer materials are first thermally extruded on the obtained mold and cooled to room temperature. Demold: excess polymer materials flowing from the through hole are cut off and then the polymer cylinder pillar arrays are lifted off from the mold. Superhydrophobic treatment: the whole polymer sample is treated using mixed liquid spray consisting of titanium oxide nanoparticles dispersed in fluoroalkylsilane ethanol solution, and the superhydrophobic cylinder pillar arrays are obtained. The method is easy to operate, low-cost, recyclable, effective for different polymer materials, and can obtain cylinder pillar arrays with large dimensions, which can realize efficient large-area and industrial fabrication of the droplet pancake bouncing surfaces.

Methods, processes, and apparatuses for preparing and transporting bitumen. Bitumen may be prilled such that a bitumen product comprising a prill core and a non-stick coating is produced. The non-stick coating may comprise asphaltenes and the prill core may comprise bitumen, deasphalted oil, or both bitumen and deasphalted oil. The resultant non-stick coated prills have reduced adhesion to transportation vessels and other non-stick coated prills at a temperature below an adhesion temperature, facilitating transport.

A hydrophobic palladium/metal organic framework (MOF) material, which is a solid catalyst material obtained by taking a porous MOF as a carrier, introducing elementary palladium by means of an immersion-reduction method, and performing polydimethylsiloxane coating layer processing. A method which uses hydrophobic palladium/MOF material to selectively catalyze hexoses to prepare 2,5-dimethylfuran comprises: dissolving a hexose into an alcohol; using the hydrophobic palladium/MOF material as a catalyst and polymethylhydrosiloxane as a hydrogen donor, reacting at 70 to 130° C. for 0.25 to 12 h under the action of an acidic additive; the concentration of the hexose in the alcohol is 0.2 to 10 wt %, and the total amount of Pd contained in the hydrophobic palladium/MOF material relative to a hexose is 0.1 to 5 mol %. The hydrophobic palladium/MOF material has a stable structure, and under the same conditions, has a catalyzing efficiency which is significantly higher than that of commercially available palladium on carbon and common palladium/MOF materials.
