A continuous acoustic chemical microreactor system is disclosed. The system includes a continuous process vessel (CPV) and an acoustic agitator coupled to the CPV and configured to agitate the CPV along an oscillation axis. The CPV includes a reactant inlet configured to receive one or more reactants into the CPV, an elongated tube coupled at a first end to the reactant inlet and configured to receive the reactants from the reactant inlet, and a product outlet coupled to a second end of the elongated tube and configured to discharge a product of a chemical reaction among the reactants from the CPV. The acoustic agitator is configured to agitate the CPV along the oscillation axis such that the inner surface of the elongated tube accelerates the one or more reactants in alternating upward and downward directions along the oscillation axis.

A system and method including providing a feed having alkyl-bridged multi-aromatic compounds to a tubular reactor, heating the tubular reactor, and cleaving an alkyl bridge of the alkyl-bridged multi-aromatic compounds.

Processes and systems for making recycle content hydrocarbons, including olefins, from recycled waste material. Recycle waste material may be pyrolyzed to form recycle content pyrolysis oil composition (r-pyoil), at least a portion of which may then be cracked to form a recycle content olefin composition (r-olefin). In some cases, the pyrolysis and cracking may be carried out in different sections of the same furnace, or in different furnaces in the same cracker facility. Pyrolysis conducted in a furnace may or may not require retrofitting a furnace previously used to crack alkanes to form olefins.

Alkylene oxides are polymerized in a tubular reactor. The alkylene oxide is continuously introduced into the tubular reactor through multiple introduction points located along the length of the tubular reactor. Monomer flow rates are increased along the length of the reactor to maintain a nearly constant concentration of unreacted alkylene oxide.

An object is to provide a novel flow reactor capable of measuring the internal temperature. The flow reactor including a tubular reaction line, wherein the flow reactor further includes an internal temperature measurement unit provided at one or more location of the tubular reaction line, the internal temperature measurement unit includes a thermometer with a temperature sensor, and the temperature sensor is inserted into the tubular reaction line.

A supercritical water oxidation-flame piloted vortex reactor has a hydrothermal flame produced within the interior of the reactor fed by a fuel including a waste water stream, and has a subcritical wash stream, including water below its critical point, that creates an upward helical flow in the material within the reactor. The hydrothermal flame and upward helical flow produce within the reactor a supercritical core region, a subcritical outer region around the core region, and a transcritical intermediate region between them. The upward helical flow serves to transfer precipitated ionic compounds out of the supercritical core region, through the transcritical intermediate region, and into the subcritical outer region where they re-dissolve. A processed flow, including purified water, is removed from an upper portion of the supercritical core region by an aspirator.

A continuous flow reactor for the efficient synthesis of nanoparticles with a high degree of crystallinity, uniform particle size, and homogenous stoichiometry throughout the crystal is described. Disclosed embodiments include a flow reactor with an energy source for rapid nucleation of the .[.procurors following.]. .Iadd.precursors to form nucleates followed .Iaddend.by a separate heating source for growing the nucleates. Segmented flow may be provided to facilitate mixing and uniform energy absorption of the precursors, and post production quality testing in communication with a control system allow automatic real-time adjustment of the production parameters. The nucleation energy source can be monomodal, multimodal, or multivariable frequency microwave energy and tuned to allow different precursors to nucleate at substantially the same time thereby resulting in a substantially homogenous nanoparticle. A shell application system may also be provided to allow one or more shell layers to be formed onto each nanoparticle.

A reactor and process for the production of bio-diesel. The reactor includes one or more coiled reaction lines. The lines are positioned within a tank containing a heat transfer media such as molten salt, maintained at about 750 F. A pump circulates the media within the tank. An emulsion of alcohol; refined feed stock, including glycerides and/or fatty acids; and preferably water is pumped through the reaction lines at temperatures and pressures sufficient to maintain the alcohol in a super-critical state. The curvature of the coils, pump pulsing, and the flow rate of the emulsion keep the emulsion in a turbulent state while in the reactor, ensuring thorough mixing of the alcohol and feed stock. The alcohol reacts with the glycerides and fatty acids to form bio-diesel. The reaction is fast, efficient with regard to energy input and waste generation, and requires minimal alcohol.
