Continuous acoustic chemical microreactor
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.
ENERGY-EFFICIENT SOLVENT-FREE METHOD FOR PRODUCING METAL CHELATES
The invention relates to a method for producing, amongst other things, amino-acid and/or hydroxycarboxylic-acid metal chelates, a solvent-free mixture of at least one metal oxide, metal hydroxide, metal carbonate or oxalate, and the solid organic acid is subjected to intensive mechanical stress. According to the invention, this is done in that the reaction partners are introduced in particle form into a fluid stream of a fluid-bed countercurrent mill operating without grinding elements, wherein mechanical activation of at least one of the reaction partners is effected by collision processes within a reaction chamber formed in a region of the fluid stream, and a solid body reaction to form the metal chelate is triggered. The novel method operates very energy-efficiently and with a high specific yield. It leads to a product having compact particles in the small, single-digit micrometer range having a comparatively narrow particle size distribution and a large surface. The product is homogenous and very pure. Thermal loading or decomposition of the organic chelate ligands, in particular of the amino acids, is likewise avoided, as are contaminants from milling and grinding element abrasion.
Self cleaning reactor system
This invention relates to a self cleaning reactor and to a process for the oligomerization of ethylene that employs a self-cleaning reactor. The reactor includes a mass of inert, particulate cleaning bodies that are entrained by the liquid in the reactor and scour the internal surfaces of the reactor during normal operation. This scouring action reduces the level of fouling on the reactor surfaces. Foulant material (polyethylene) is removed from the process on a continuous basis but the cleaning bodies remain within the reactor.
Synthesis method and synthesis device for cyclododecene
A synthesis method and a synthesis device of cyclododecene according to the present invention have a high conversion rate of cyclododecatriene which is a reactant and a high selectivity of cyclododecene which is a required product, and even so, have an effect of significantly decreasing a reaction time. In addition, the method and the device have an excellent conversion rate of cyclododecatriene and an excellent selectivity of cyclododecene, while maintaining excellent reactivity without an organic solvent such as ethanol.

METHOD FOR PYROLYTIC DECOMPOSITION OF GASEOUS HYDROCARBONS AND APPARATUS FOR PERFORMING THE SAME
The invention relates to the chemical industry and can be used for processing methane and other volatile, liquid, solid fusible hydrocarbons when producing hydrogen, soot, and other flammable gases. The invention relates to a method for the pyrolytic decomposition of hydrocarbons, in which a pyrolysis reactor arranged in a space bounded by a lining is heated by flue gases generated by combusting a hydrogen-enriched mixture of air and gaseous hydrocarbons, while ensuring a maximum decrease in CO.sub.2 emissions into the atmosphere. The invention also relates to a unit for the pyrolytic decomposition of hydrocarbons. The technical result is a high degree of separation of hydrogen and carbon by fast high-temperature pyrolysis at atmospheric pressure without oxygen supply and without CO.sub.2 production.
