摘要:
Disclosed is a process for the production of ammonia comprising a step wherein synthesis gas is formed by catalytic partial oxidation. Also disclosed is a process of producing urea, wherein ammonia is formed in a process involving a step of catalytic partial oxidation, and carbon dioxide formed in the same process is reacted with said ammonia so as to form urea.
摘要:
In some implementations, a method for separating components includes receiving off-gas from a Fischer-Tropsch hydrocarbon synthesis reaction process. The off-gas is scrubbed with a light oil at least proximate atmospheric temperature to substantially remove a mixture of C3 and C4. The C3 and C4 are separated from the mixture into two separate streams using distillation columns in a Fischer-Tropsch system.
摘要:
A bottom fraction of a product of a hydrocatalytic reaction is gasified to generate hydrogen for use in further hydrocatalytic reactions. In one embodiment, an overhead fraction of the hydrocatalytic reaction is further processed to generate higher molecular weight compounds. In another embodiment, a product of the further processing is separated into a bottom fraction and an overhead fraction, where the bottom fraction is also gasified to generate hydrogen for use in further hydrocatalytic reactions.
摘要:
A method of operating a fuel cell system on a by-product gas containing a fuel constituent. The fuel cell system includes a fuel reformer for forming a reformate stream, a combustor for supplying heat energy to the fuel reformer, and a fuel cell stack. The method includes the steps of separating a by-product gas into a purified gas stream and a residual stream with a gaseous fuel purifier, feeding the purified gas stream to the fuel reformer configured to transform the purified gas stream to produce a reformate stream, and feeding the residual gas stream to a combustor configured to provide heat energy to the fuel reformer. The purified gas stream contains a higher concentration of preferable fuel constituents and a lower concentration of contaminants than the residual gas stream.

A method and system for producing carbon dioxide and electricity from a gaseous hydrocarbon feed using a solid oxide fuel cell, a water-gas shift reactor and a reformer.
摘要:
Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zur Erzeugung eines Wasserstoff und/oder Kohlenmonoxid umfassenden Gasproduktes (21), wobei ein aus einem Kohlenwasserstoffe enthaltenden Ausgangsstoff (1) gebildeter Kohlenwasserstoffeinsatz (5) gemeinsam mit überhitztem Dampf (13) einer bei erhöhtem Druck ablaufenden Dampfreformierung (D) zugeführt wird, um ein Wasserstoff und Kohlenmonoxid enthaltendes Syntheserohgas (17) zu erhalten, aus dem das Gasprodukt (21) gewonnen wird. Kennzeichnend hierbei ist, dass Kesselspeisewasser (8) bei einem höheren als seinem kritischen Druck Wärme zugeführt wird (E1), um überkritisches Wasser (10) zu erhalten, von dem nachfolgend zumindest eine Teilmenge (12) als Treibmedium in einer Dampfstrahlpumpe (V) eingesetzt wird, mit deren Hilfe der Kohlenwasserstoffeinsatz (5) und/oder ein zu dessen Bildung eingesetzter Stoff verdichtet wird.
摘要:
A hydrogen generation system (100) includes a reformer (10) that produces a hydrogen-containing gas from a raw material and reforming water, a combustor (11) that burns the hydrogen-containing gas and air, an exhaust-gas path (12), a cooling-water path (13), a condenser (14) that produces condensed water by exchanging heat between the exhaust gas and the cooling water, a water tank (21) that stores the cooling water, a water pump (19) that feeds the cooling water into the condenser (14), a reforming-water path (18) along which part of the cooling water is passed into the reformer (10) to serve as reforming water which is branched from the cooling-water path (13), and a controller (30). The water tank (21) is disposed at a position higher than the water pump (19). The water pump (19) is disposed at a position higher than the junction (40). The controller (30) detects an insufficient supply of the cooling water on the basis of the rotational speed of the water pump (19).
