A reactor system and a process for carrying out steam cracking of a feed gas comprising hydrocarbons is provided, i where the heat for the reaction is provided by resistance heating by means of electrical power, so that a product stream comprising at least one olefin compound is obtained.

The invention relates to a device, stacked plate reactor and to a method for investigating chemical processes to be carried out simultaneously or almost at the same time on a large number of functional element variations of the process parameters.

A waste gas treatment equipment includes a reactor defining a waste gas reaction space, an induction heating pipe disposed in and dividing the waste gas reaction space into inner and outer spaces, a coil protector disposed in the outer space and surrounding the induction heating pipe, a flow guide tube inserted into the inner space through a bottom wall of the reactor, and a high frequency coil disposed in the coil protector. A catalyst barrel has a barrel body sleeved on a top portion of the flow guide tube, including an outer wall provided with a plurality of through holes, and defining a receiving space communicating with the through holes and for receiving a catalyst. A scraper mechanism is provided in the reactor for scraping dust or crystals attached to the inner wall surface of the flow guide tube and the outer wall of the barrel body.

The invention relates to a device, stacked plate reactor and to a method for investigating chemical processes to be carried out simultaneously or almost at the same time on a large number of functional element variations of the process parameters.

An apparatus for accelerated multi-stage synthesis of quantum dots (QDs) includes an injector which injects a material for producing QDs, a first reactor connected to the injector and including at least one selected from a coil reactor and a plate reactor, a second reactor connected to the first reactor and including at least one selected from the coil reactor and the plate reactor, and a first junction connected between the first reactor and the second reactor and provided with an inlet for injecting the material for producing the QDs.
