Catalytic hydrogenation process utilizing multi-stage ebullated bed reactors

A process for catalytic multi-stage hydrogenation of heavy carbonaceous feedstocks using catalytic ebullated bed reactors is operated at selected flow and operating conditions so as to provide improved reactor operations and produce increased yield of lower boiling hydrocarbon liquid and gas products. The disclosed process advantageously takes advantage of an external gas / liquid separation unit associated with the first stage reactor to allow for a more efficient and effective catalytic hydrocracking process. The more efficient process is primarily a result of the increased catalyst loading and lower gas hold-up in the ebullated reactors.

Metal Nitrides and Process for Production Thereof

To provide a method for efficiently producing a high quality metal nitride containing a small amount of impurities, particularly gallium nitride.A method for producing a metal nitride characterized by employing a container made of a nonoxide material. By using a nonoxide for a material of a container to be in contact with a raw metal or a metal nitride to be formed, reaction or adhesion of the raw metal or the metal nitride to be formed to the container can be avoided, and inclusion of oxygen derived from the material of the container can be prevented, whereby a high quality metal nitride having high crystallinity will be obtained. By securing a certain or larger supply amount and a certain or higher flow rate of the nitrogen source gas, the raw metal can be converted into a nitride with an extremely high conversion, and a metal nitride having a small amount of an unreacted raw metal remaining and containing a metal and nitrogen in a stoichiometric constant can be obtained with a high yield. The obtained metal nitride having a small amount of oxygen included and containing a metal and nitrogen in a stoichiometric constant, is very useful as a raw material for bulk crystal growth.

Light emitting device and method for manufacturing the same

A light emitting element containing an organic compound has a disadvantage in that it tends to be deteriorated by various factors, so that the greatest problem thereof is to increase its reliability (make longer its life span). The present invention provides a method for manufacturing an active matrix type light emitting device and the configuration of such an active matrix type light emitting device having high reliability. In the method, a contact hole extending to a source region or a drain region is formed, and then an interlayer insulation film made of a photosensitive organic insulating material is formed on an interlayer insulation film. The interlayer insulation film has a curved surface on its upper end portion. Subsequently, an interlayer insulation film provided as a silicon nitride film having a film thickness of 20 to 50 nm is formed by a sputtering method using RF power supply.

High-purity fishy smell and foreign odor-free fish collagen protein peptide and preparation method thereof

The invention discloses a high-purity fishy smell and foreign odor-free fish collagen protein peptide and a preparation method thereof. The preparation method comprises the following steps: cleaning fish skins, and then cutting into blocks and mincing; performing stirring treatment with NaCl solution; centrifugally degreasing to remove paraprotein; adding water to regulate the pH value of initial slurry to be 8.0-8.5; performing combined gradient enzymolysis on alkali protease and neutral protease; deactivating enzyme after the enzymolysis is ended; performing adsorption bleaching by activated carbon; and then performing rough filtration, fine filtration, evaporation concentration and spray drying to prepare the high-purity fishy smell and foreign odor-free fish collagen protein peptide. The high-purity fishy smell and foreign odor-free fish collagen protein peptide disclosed by the invention has a simple process and is easy to industrial production; fishy smell, foreign odor and non-collagen proteins are fully removed in production; the low-temperature biological enzymolysis technology is adopted, and other substances are not added, thereby, the product quality is improved; an obtained fish collagen protein peptide powder has the characteristics the content of amino acid hydroxyproline is not less than 9 percent, and the average molecular weight is lower than 1000Dal; no fishy smell or foreign odor cannot generated, and obvious fishy smell or foreign odor also cannot be generated through heating treatment under the acid conditions. The high-purity fishy smell and foreign odor-free fish collagen protein peptide can be widely applied to processing of various foods and cosmetics as a green functional ingredient.

Method for producing synthetic leather by using solvent-free double-component polyurethane scraping and coating method

The invention discloses a method for producing synthetic leather by using a solvent-free double-component polyurethane scraping and coating method and the synthetic leather produced by using the same. The method comprises the following steps: (1) controlling the flow of a material loading machine so that an M material and an N material are mixed in the mixing chamber of the material loading machine and then poured, scraped and coated to release paper coated with an isolation layer, drying so as to obtain a foamed material layer, wherein the coating amount of scraping and coating is 50-2000g/m<2>; (2) pressing and compounding the foamed material layer, heating and solidifying; and (3) coiling, curing, and separating out the release paper at last, so as to obtain the synthetic leather finished product. According to the invention, an organic solvent and water are not used in the synthesis and mixing of polyurethane resin on a foaming layer and a bonding layer and in the various links of embarkation. Compared with the method for producing the foaming layer with a water-based polyurethane composite material, the method disclosed by the invention can greatly reduce energy consumption; and the synthetic leather has good property and excellent hand feeling.
