The invention proposes an apparatus (110) comprising a multitude of tubes. At least one of the tubes is set up as a reaction tube (112) for at least one feedstock to flow through. The apparatus (110) has at least one energy recovery shell (130) at least partly surrounding the reaction tube (112). The energy recovery shell (130) has at least one thermoelectric generator set up to convert heat to electrical energy.

The present disclosure relates to a process and an apparatus for the purification of polyetherketoneketone (PEKK). The process involves purifying the PEKK by using a solvent with continuous reflux to obtain the purified PEKK with enhanced product characteristics. The process of the present disclosure is simple, and economical, reduces the solvent usage and time for purification, and produces purified PEKK with comparatively high yield and purity.

The invention generally relates to systems and methods for increasing reaction yield. In certain embodiments, the invention provides systems for increasing a yield of a chemical reaction that include a pneumatic sprayer configured to generate a liquid spray discharge from a solvent. The solvent includes a plurality of molecules, a portion of which react with each other within the liquid spray discharge to form a reaction product. The system also includes a collector positioned to receive the liquid spray discharge including the unreacted molecules and the reaction product. The system also includes a recirculation loop connected from the collector to the pneumatic sprayer in order to allow the unreacted molecules and the reaction product to be recycled through the pneumatic sprayer, thereby allowing a plurality of the unreacted molecules to react with each other as the unreacted molecules cycle again through the system.

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.

There is a high-temperature tube bundle reactor built from material derived from metal oxides such as alumina-zirconia. The heat exchange surfaces of the reactor have a specific surface finish, and the bulk matrix of the material of the various components of the reactor has a specific grain, pore size and porosity characteristics. There is also a high-temperature redox process using the reactor.
