摘要:
Embodiments are disclosed that relate to a compact steam boiler which may provide steam to a steam reformer in a fuel cell system. For example, one disclosed embodiment provides a steam boiler including an outer shell and a first inner tube and a second inner tube within the outer shell, the first and second inner tubes spaced away from one another. The steam boiler further includes a twisted ribbon positioned inside each of the first and second inner tubes.
摘要:
A reactor and process for using same, for containing a solid catalyst for heterogeneous gas-phase reactions into which reactor there extends at least one inlet pipe for a molecular oxygen-containing gas which has means for surrounding a substantial portion of the pipe in the reactor with an inert fluid and optionally also has means for suppressing ingress to the inlet pipe from the reactor of flame, reagents, products, catalyst or combinations thereof. The reactor and process are particularly suitable for fluid bed reactions.
摘要:
A method and apparatus for carrying out partial oxidation of hydrocarbon feeds to produce hydrogen rich gases suitable for steam reforming, utilizes a monolithic platinum and palladium containing catalyst. The process comprises introducing an oxygen containing oxidant gas (e.g., air), steam and a hydrocarbon feed into a catalytic partial oxidation apparatus comprising an adiabatic reaction vessel. The oxidation catalyst preferably comprises platinum, palladium and optionally rhodium distended upon a stabilized alumina washcoat. At least one half by weight of the hydrocarbon feed is catalytically oxidized in the monolith at a high throughput rate to produce an effluent suitable for further processing, such as steam reforming.
摘要:
A catalytic synthesis method, a device and a system for ammonia synthesis through orderly regulation of the electronic domain of nitrogen are provided. Nitrogen and hydrogen are used as raw materials, and a multi-composition material with magnetic material as active site is used as a catalyst, thermal field, magnetic field and electric field or thermal field and electromagnetic field are applied to nitrogen, hydrogen and catalyst at the same time. The invention adopts the catalytic synthesis method, device and system for the mild ammonia synthesis at low temperature and low pressure conditions through orderly regulation of the electronic domain of nitrogen.

The present disclosure provides a premixer for at least two gases, comprising: a tabular body having a closed end and an opposite, open end; a first flow passage for receiving a first gas, the first flow passage axially extending through the closed end into the tabular body in a sealable manner; a conical tube arranged in the tabular body, wherein a small end of the conical tube communicates with the first flow passage, and a large end of the conical tube extends toward the open end with an edge thereof being fixed to an inner wall of the tabular body, thereby defining a sealed distribution chamber between the tabular body and the conical tube; and a second flow passage arranged on a side portion of the tabular body for receiving a second gas, wherein the second flow passage communicates with the distribution chamber, so that the second gas can be introduced into said conical tube via the distribution chamber in a substantially radial manner. The present disclosure further relates to a radially fixed bed reactor comprising the premixer, a reaction system of oxidative dehydrogenation of butene comprising the racially fixed bed reactor, and a corresponding process.
