Abstract:
A decomposition reaction apparatus for the decomposition treatment of a thermosetting resin, which comprises a reaction apparatus comprising an introduction section for introducing a resin composition containing the thermosetting resin and a solvent containing a monomer component of the thermosetting resin or a component similar to the monomer component, a decomposition reaction section for heating and pressuring the resin composition and the above solvent so as for the solvent to have a supercritical state or a subcritical state, to thereby prepare a treated and recovered product containing a recycled resin formed by the reduction of the molecular weight of the above thermosetting resin, and a discharge section for discharging the treated and recovered product. In the above reaction apparatus, the introduction of the resin composition and the solvent, the decomposition treatment of the thermosetting resin in the decomposition reaction section and the discharge of the treated and recovered product from the discharge section are all carried out continuously, and therefore, a raw material for a recycled resin composition using an industrial or general waste containing a thermosetting resin as the above resin composition can be produced continuously.

Abstract:
Enhanced macromixing, mesomixing, and micromixing of multiple discrete reactant streams, particularly for precipitation reactions of low density pumpable fluids, are obtained by controlled continuous high pressure multiple reactant streams flowing into a chemical mixer/reactor. Individual reactant streams are pressurized to about 8,000 to 50,000 psi and achieve velocities up to about 250 meters/second in the final stage of the chemical mixer/reactor. Reactant flows are controlled by a combination of a fixed restriction and a variable driving pump.
Abstract:
A process and an apparatus for recovering a noble gas, which can recover a noble gas exhausted from a noble gas employing system efficiently and also can supply the noble gas of a predetermined purity to the noble gas employing system and which can reduce consumption of the noble gas. In the process and apparatus for recovering a noble gas, when a noble gas contained in an exhaust gas exhausted from a noble gas employing system operated under reduced pressure is recovered, switching between introduction of the exhaust gas to a recovery system and exhaustion of the exhaust gas to an exhaust system is carried out under reduced pressure, and this switching operation is carried out depending on the content of impurity components contained in the exhaust gas or on the running state of the noble gas employing system.
Abstract:
Systems and methods for heating, reacting, and/or treating a stream containing oxidizable matter. Recycle reactor is used alone or in conjunction with plug-flow reactor. Density differences in the recycle reactor facilitate flow within the recycle reactor without substantial external heat exchange.
Abstract:
A method for producing an enhanced adsorbent and/or enhanced catalytic particle and/or for producing a catalytic particle, comprising the steps of: (a) removing an effective amount of air from a closed chamber containing an adsorbent and/or catalytic particle, wherein the resultant chamber pressure is less than one atmosphere; (b) raising the chamber pressure with an inert gas to at least one atmosphere; (c) contacting the particle with an energy beam of sufficient energy for a sufficient time to thereby enhance the adsorbent and/or catalytic properties of the particle and/or produce catalytic properties in the particle. A continuous process directed to step (c) alone is also provided. Also disclosed are adsorbent and/or catalytic particles, methods of contaminant reduction or elimination, including room temperature catalysis, particle binders, apparatuses of the present invention, and methods of increasing the surface area of adsorbent and/or catalytic particles.
