	The reactor chamber itself will have no active role and will simply be a container that can be connected to different input and output lines, and is optimized for mixing of components and maintenance of optimal reaction conditions. Use of an external frame seems to be fairly standard in industry and would allow separate mixing, reaction, and velocity reduction zones to be simply, and securely combined. FBRs could be a versatile platform for many OSE natural resource and chemical engineering ecologies. The reactor core will be designed so that it can be used without modification in a wide variety of applications through reconfiguration of the components. As OSE identifies chemical processes that should be conducted in a fluid bed reactor a thorough open source literature review should be conducted within this page and necessary subsystems and components identified.

			=Basics=
	Fluidized bed reactors (FBR) are chambers that allow the mixing of liquid or gas substrates with powdered catalysts such that the catalyst acts like a fluid, maximizing mixing and interaction. The basic configuration is detailed to the right where a substrate is passed upward into the chamber under pressure through a plate that supports the catalyst. FBRs are essential for the production of many materials and chemicals, and could be an effective tool for several basic capabilities of the GVCS.

	An OSE FBR should be built of discrete components that are integrated rather than dependent on one another, so a machine can be assembled into configurations for applications that use different pieces of equipment. This approach is also necessary for scrum and decentralized development by breaking down this complex machine into self-evident pieces. As a complex machine it will also be useful to develop components that are involved in a common task or reaction parameter as part of a subsystem, an example would be thermal flow controllers that control injection of substrate and vacuum pumps that remove products. Components of subsystems should be designed to control a specific parameter in the most flexible way possible while being under the control of a system controller (computer) that integrates the system components into a cohesive action. This will allow component actions in the form of programs to be distributed and replicated. Much of this is already industry standard practice.

	FBRs have been been studied for their effectiveness in biomass pyrolysis applications and have been found to be effective at controlling the gas and liquid phase processes. A typical configuration of a FBR for pyrolysis is shown with simplified components at http://www.pyne.co.uk/Resources/user/Bubbling%20fluid%20bed.bmp. Pyrolysis as a degradative process can yield a variety of products which are characterized generally as gas and liquid combustibles and solid char. Fast pyrolysis yields a high fraction of oily liquid products, while gasification yields gaseous products. Pyrolysis in an FBR will primarily be for the production of chemicals or liquid components as the [[Gasifier Burner]] seems to be a more appropriate technology for conversion of biomass to combustible gas for heating.

	A reactor configured for polylactic acid dehydration will use a reactor core that can maintain a near vacuum (0.5 torres) and can be heated to 200 C. The melt\solid state would be disturbed by gas flow and heat must be added through a heat jacket either configured for hot oil, steam, or electric heating. The bottom port will be ~~seal~~ with a screw in end cap with high heat O-ring and a sealing grease if temperature allows. The reaction zone will not be constrained by a distributor plate.

	A reflux condenser removes moisture from the product stream which is necessary to prevent fouling of the vacuum pump. Condensers use a lower temperature to cause gases to enter liquid phase and collect the liquid. A Dean-Stark apparatus is a form of condenser that is commonly used, it is h shaped with the right side ~~connnected~~ to the reaction and the a collecting chamber connected to the bottom left.
