摘要:
The present invention involves a process and materials for simultaneous desulfurization and water gas shift of a gaseous stream comprising contacting the gas stream with a nickel aluminate catalyst. The nickel aluminate catalyst is preferably selected from the group consisting of Ni2xAl2O2x+3, Ni(2−y)Ni0yAl2O(5−y), Ni(4−y)Ni0yAl2O(7−y), Ni(6−y)Ni0yAl2O(9−y), and intermediates thereof, wherein x≧0.5 and 0.01≦y≦2. Preferably, x is between 1 and 3. More preferably, the nickel containing compound further comprises Ni2xAl2O2x+3−zSz wherein 0≦z≦2x.

摘要:
The present invention provides a reactor containing catalysts that are situated on or within a cloth like material which is either in a filter cake-like shape or a spiral wound reactor configuration. One application is the desulfurization of synthesis gas.
摘要:
An inexpensive heat exchanger is disclosed, wherein the heat exchanger is made up of a plurality of plates and each plate has at least one channel defined in the plate. The plates are stacked and bonded together to form a block having conduits for carrying fluids, and where each fluid is in thermal communication with the other fluids.
摘要:
An apparatus is disclosed for the generation of hydrogen peroxide. The apparatus provides for the production of a large scale volume of hydrogen peroxide by the generation of a liquid bearing bubble cloud. The bubbles are generated with a tiny volume before flowing over the reactor bed to generate the hydrogen peroxide.
摘要:
A novel mixing apparatus and process for mixing at least two fluids are disclosed. Excellent mixing and superior pressure drop characteristics are achieved in a device comprising at least two supply channels to feed a mixing chamber and create a vortex. The alignment of the supply channels is such that fluids are introduced into the chamber at both tangential and radial directions. In the case of gas/liquid mixing, particularly advantageous is the injection of the liquid stream tangentially and the gas stream radially. When two liquid streams are mixed, it is desirable to distribute them into fine, interdigitated channels prior to introduction into a supply channel and finally into the chamber. The mixed stream is generally withdrawn from the center of the swirling vortex and in a direction perpendicular to the plane of the vortex.

A novel apparatus for mixing and reacting at least two fluids are disclosed. Excellent mixing and superior pressure drop characteristics are achieved in a device comprising at least two supply channels to feed a mixing chamber and create a vortex. The alignment of the supply channels is such that fluids are introduced into the chamber at both tangential and radial directions. In the case of gas/liquid mixing, particularly advantageous is the injection of the liquid stream tangentially and the gas stream radially. Reaction of the fluids can take place within the mixing chamber or in a separate reactor in fluid communication with the mixing chamber outlet. The mixer/reactor apparatus is especially useful for reactions where rapid diffusion is critical.
摘要:
A process for simultaneously testing a plurality of catalysts using combinatorial chemistry has been developed. The process involves containing the plurality of catalysts in an array of parallel reactors with each reactor containing a bed of catalyst. Each bed of catalyst is then simultaneously contacted, at reaction conditions, with a reactant to form an effluent of each reactor. The reactant or an inert fluid is at a space velocity sufficient to fluidize the catalyst beds. Each of the effluents is analyzed.
