Processes and systems for the production of heavy isoparaffinic hydrocarbons include feeding hydrogen and a mixed isoolefin stream, including C8-C12 olefins, isoolefins, and oligomers, and C8-C12+ hydrogenated hydrocarbons to a trickle-bed reactor system. The hydrogen and mixed isoolefin are reacted over a hydrogenation catalyst, producing a liquid effluent comprising hydrogenated hydrocarbons and unreacted olefins and oligomers, and a vapor effluent comprising hydrogenated hydrocarbons, hydrogen and unreacted olefins and oligomers. The liquid effluent is fed to a first heat exchanger, producing a cooled liquid effluent stream, which is combined with the vapor effluent, producing a mixed phase effluent. The mixed phase effluent is cooled in a second heat exchanger, producing a partially condensed effluent, which is fed to a drum, producing a vent stream, a hydrogenated product stream having greater than 95 wt % C8-C12 saturated hydrocarbons, and a hydrogenated recycle stream. The hydrogenated product stream may be provided to downstream blending systems.

The present invention is generally directed to a reactor for the production of low-carbon syngas from captured carbon dioxide and renewable hydrogen. The hydrogen is generated from water using an electrolyzer powered by renewable electricity or from any other method of low-carbon hydrogen production. The improved catalytic reactor is energy efficient and robust when operating at temperatures up to 1800° F. Carbon dioxide conversion efficiencies are greater than 75% with carbon monoxide selectivity of greater than 98%. The catalytic reactor is constructed of materials that are physically and chemically robust up to 1800° F. As a result, these materials are not reactive with the mixture of hydrogen and carbon dioxide or the carbon monoxide and steam products. The reactor materials do not have catalytic activity or modify the physical and chemical composition of the conversion catalyst.

A method of installing a temperature measuring device inside a reactor tube while filling the tube with catalyst is provided. The method includes inserting a positioning system, including a single inflatable bladder connected at a central location to a centering ring, into a reactor tube, the reactor tube comprising a distal end and a proximal end. Then inserting the centering ring around the temperature measurement device. Then locating the positioning system at a first predetermined distance from the distal end, and inflating the single inflatable bladder, thereby centering the centering ring and the temperature measurement device within the SMR tube. Then introducing catalyst into the SMR tube, thereby enclosing the temperature measurement device in catalyst.

A submerged propylene hydration micro-interface strengthening reaction system and a method are proposed. The system includes a reactor, a first micro-interface generator and a second micro-interface generator. Through the micro-interface generators, the propylene is broken to form micron-scale bubbles, which are mixed with reactants and deionized water to form a gas-liquid emulsion, so as to increase a phase boundary area between gas and liquid phases, and achieve a strengthening mass transfer effect under a lower preset operating condition. The micro-scale bubbles can be fully mixed with the deionized water to from a gas-liquid emulsion. By fully mixing gas and liquid phases, it can ensure that the deionized water in the system is in full contact with propylene, and they are fully in contact with the catalyst, which effectively improves the efficiency of preparing isopropanol.
