The method includes synthesizing olefin from the syngas in the vessel, wherein the olefin includes ethylene, propylene, or butene, or any combinations thereof.

A catalytic reaction analysis dual reactor system and a method for measuring the catalytic activity of a catalyst by correcting for non-catalytic effects with the catalytic reaction analysis dual reactor system. The dual reactor system contains a first reactor comprising a first catalyst on a first catalyst support, and a second reactor comprising a second catalyst support, wherein the particle size and amount of the first catalyst and the second catalyst support are substantially the same, and the effect of the catalyst is isolated by correcting the result obtained from the first reactor containing the catalyst with the result obtained from the second reactor containing the catalyst support.

Provided herein is a gas mixer for the safe mixing of a hydrocarbon containing gas with a gaseous oxidant. The gas mixer and method for mixing described includes a closed mixing vessel where bubbles of gas injected at the bottom of the vessel are mixed during their rise to the top of the vessel, forming a homogeneous mixture that can safely be removed. This simple design and method allows for safe mixing of gases and is applicable to catalytic oxidative processes such as oxidative dehydrogenation of paraffins where there is a risk of thermal runaway of reactions.

Systems, devices, and methods for transferring heat associated with an interface corresponding to a reactor. In some aspects, a system includes a sleeve having a body portion that defines a channel that extends from a first end to a second end of the body portion. The channel is configured to define a flow path that extends through a flange that is coupled to a pipe via a welding point a lip portion extending radially away from the first end and configured to be positioned between the flange and a reactor.

Systems and methods are provided for hydrogenation of CO.sub.2 in a reverse flow reactor environment via a reverse water gas shift reaction. A reverse flow reactor environment is suitable for performing endothermic reactions at high temperatures, where a reactant flow is passed into the reactor in a first portion of the cycle in a first flow direction while a combustion or heating flow is passed into the reactor during a second portion of the reaction cycle from the opposite direction. This can allow for efficient heating of surfaces within the reactor to provide heat for the endothermic reverse water gas shift reaction while reducing or minimizing incorporation of combustion products into the desired reaction products.

The invention provides a thermal cracking system which comprises a reactor, and a feed module or a solid product discharge module. The feed module transports a feed material from the outside environment to the reactor. While being transported, the feed material is heated by the feed module to become molten and fills up the interior of the feed module, thereby preventing air from entering the reactor. The solid product discharge module transports a solid product from the reactor to the outside environment. One end of the solid product discharge module is connected with the reactor. The other end of the solid product discharge module comprises a first opening interfacing with the outside environment. When the solid product is transported to the outside environment, the opening size of the first opening is selected such that the speed at which the solid product is entering the solid product discharge module form the reactor is equal to or greater than that at which the solid product is leaving the solid product discharge module, through the first opening, and into the outside environment. Benefit of the invention includes a higher production efficiency and enhanced safety for a thermal cracking system at industrial scale.

Disclosed is a system and method for wirelessly monitoring 5 process conditions within a reactor vessel. A plurality of sensor-enabled radio frequency identification (RFID) tags are disposed at unspecified or random locations throughout a catalyst bed of a vessel and are used to measure various conditions within the vessel. The sensor-enabled RFID tags are encoded with individual identification codes and are wirelessly linked to multiple 10 transceivers. The use of multiple transceivers allows for the application of triangulation methods to identify the location of each of the sensor-enabled RFID tags in three dimensional space and for the interrogation of each sensor-enabled RFID tag to receive responsive transponder signals that carry information representative of the sensed condition within the reactor.
