The invention relates to a method for producing hydrogen, in which, in a non-electrolytic method, a carbonaceous feed material is converted into non-electrolytically produced hydrogen and one or more further non-electrolytically produced products, and furthermore excess steam is provided using the non-electrolytic process. According to the invention at least a part of the excess steam is used at least intermittently to provide feed steam, which is converted by means of steam electrolysis to electrolytic hydrogen and electrolytic oxygen. The present invention also relates to a corresponding plant.

Systems and methods for integrated glycerol carbonate and/or urea production. This disclosure pertains to development of a process for production of glycerol carbonate and/or urea from ammonia, carbon dioxide and glycerol. The process integrates glycerol carbonate production into a urea production process. The urea produced in the production facility may be used to produce glycerol carbonate by reacting urea with glycerol. The ammonia generated by glycerol carbonate production may be recycled back to urea production. Unreacted urea from the glycerol carbonate production may be separated and recycled to the urea product stream. The systems and methods can reduce the cost for urea production and increase product value of the excessive glycerol produced from other chemical plants.

Provided is a water-soluble film for molding a packaging capsule which is capable of enclosing chemical agents especially a detergent, has a robust property that prevents leakage of the detergent through suitable thickness and strength and an easy-processing property that keeps robustness not to make a drawn portion break in mold-processing such as deep drawing, further has a soluble resistance that does not make the chemical agent elute within 30 seconds in water at 20° C. and a complete-solubility property within a short period of time in dish-washing and clothes-washing, also has sufficient solubility and complete-solubility properties for film portions around the perimeter edge pasted with a water-soluble film for a top, and exhibits a strong-sealing property to have a temporal stability.

A water-soluble film comprises one or more kinds of anion-group-modified polyvinyl alcohols including repeating units from a fatty acid vinyl ester comonomer and anion-group-containing repeating units, in which a degree of saponification thereof is set from 91 mol% or more to 99 mol% or less and a degree of modification by anion groups is set from 1.0 mol% or more to 6.0 mol% or less so that an amount of anion-group modification is set from 1.0 mol% or more to 3.5 mo%l or less to a total amount of the anion-group-modified polyvinyl alcohols, and are formed by including less than 45 parts by mass of a plasticizer per 100 parts by mass of a total amount of the anion-group-modified polyvinyl alcohols, and have a tensile modulus of 100 MPa or less.

A process for preparing C.sub.2 to C.sub.5 olefins includes introducing a feed stream comprising hydrogen and at least one carbon-containing component selected from the group consisting of CO, CO.sub.2, and mixtures thereof into a reaction zone. The feed stream is contacted with a hybrid catalyst in the reaction zone, and a product stream is formed that exits the reaction zone and includes C.sub.2 to C.sub.5 olefins. The hybrid catalyst includes a methanol synthesis component and a solid microporous acid component that is selected from molecular sieves having 8-MR access and having a framework type selected from the group consisting of CHA, AEI, AFX, ERI, LTA, UFI, RTH, and combinations thereof. The methanol synthesis component comprises a metal oxide support and a metal catalyst. The metal oxide support includes titania, zirconia, hafnia or mixtures thereof, and the metal catalyst includes zinc.

The present invention relates to a monolith catalyst for carbon-dioxide/methane reforming and a method of manufacturing the same, and more particularly to a novel monolith catalyst for a reforming reaction having improved thermal durability, configured such that a sintering inhibiting layer is formed by coating the surface of a monolith support with at least one element selected from the group consisting of Group 2, 3, 6, 13, 15 and 16 elements among elements in Period 3 or higher and an active catalyst layer is formed on the sintering inhibiting layer, thereby preventing carbon deposition and catalyst deactivation due to deterioration even upon reaction at high temperatures.
