A flow reactor having two or more raw material feeding units, a mixing unit to mix raw materials fed from the raw material feeding units, and a reactor unit in which a mixed solution prepared in the mixing unit flows, wherein at least a part of an inner wall of the reactor unit is formed of a fluororesin containing a conductive filler.

The invention relates to a multitubular reactor for dehydrogenation of liquid phase alcohol dehydrogenation and a method of liquid phase alcohol dehydrogenation. Most of the alcohol dehydrogenation reaction is endothermic reaction, the reaction temperature is high and the equilibrium conversion rate is low.

A chemical reactor for use in a chemical process wherein a reactant and/or a target product is prone to produce undesirable byproducts through secondary reactions. The reactor is configured with a first flow passage for passing a flow of an overly reactive reactant; a permeable first wall for controlled flow of the overly reactive reactant into a second flow passage providing a flow of a second reactant; a permeable second wall having a catalyst supported on an inner surface thereof for catalyzing reaction of the reactants flowing in the second flow passage; the permeable second wall passing through a flow containing the target product; and a non-permeable third wall defining a third flow passage for exiting the product mixture. The reactor can be employed in selective oxidation, oxidative dehydrogenation, and alkylation processes to reduce the formation of byproducts.

The problem addressed by the invention is that of providing a plasma reactor for decomposition of hydrocarbons which allows stable operation over a prolonged time period. This problem is solved by a plasma reactor for decomposing a hydrocarbon fluid, which comprises a reactor chamber surrounded by a reactor wall and further comprises at least one hydrocarbon inlet and an outlet. A plasma torch having at least two electrodes, which comprise a base part at a first end, is fixed to the reactor wall. At a second end, the electrodes comprise a burner part which projects into the reactor chamber, and a plasma zone is defined between the burner parts of adjacent electrodes. In a region between the plasma zone and the outlet, the hydrocarbon inlet opens into the reactor chamber, and the hydrocarbon inlet is oriented toward the plasma zone such that hydrocarbon fluid flowing therefrom is directed towards the plasma zone. In the plasma reactor disclosed herein, primarily small C particles are formed which prevent fouling or overgrowing of the reactor chamber. Furthermore some large and heavy C particles, which may statistically be formed, penetrate the plasma cloud and can attach specifically to the electrodes.

A system and a process for reducing greenhouse gas emissions are disclosed herein. The system may include a combustion zone, a catalytic converter, a methanation reactor, a compressor, a normal venting unit, a vacuum protection unit, and a control system. The process may include feeding a fuel, a methane-containing gas, and an oxygen-containing gas into a first reactor unit, and producing a combustion products stream comprising carbon monoxide, carbon dioxide, and water. The process may include cooling the combustion products stream via a cooling system, feeding the cooled exhaust stream and hydrogen to a second reactor unit. The second reactor unit may include a first catalyst for reacting oxygen with carbon monoxide to form carbon dioxide, and a second catalyst for reacting carbon dioxide with hydrogen to produce methane. The process may include recovering an effluent from the second reactor unit and feeding it to the first reactor unit.

The present disclosure provide for methods of reforming a hydrocarbon such as methane. In an aspect, when the method is driven via renewable energy (e.g., use of solar energy, wind energy, or other renewable energy) and coupled with zero-energy input product gas separation, this enables the capture of pure CO.sub.2 (i.e., carbon sequestration) and carbon-neutral utilization of methane can be achieved. As a result, the present disclosure can provide for a method to reform methane with zero-energy input product gas separation.

Provided herein are processes for carrying out a chemical reaction of a substrate in a diluted reaction mixture. The processes include conducting the reaction mixture having reaction product and solvent to a filtration membrane which is permeable to the solvent but impermeable to the reaction product. Solvent which permeates the filtration membrane for dilution of the substrate feed is recycled.

A cascade reactor scheme with acid and hydrocarbon flowing in reverse directions. The systems and processes for alkylation of olefins herein may include providing a first olefin to a first alkylation zone, and a second olefin to a second alkylation zone. Isoparaffin may be provided to the first alkylation zone. The isoparaffin and first olefin may be contacted with a partially spent sulfuric acid in the first alkylation zone to form a spent acid phase and a first hydrocarbon phase including alkylate and unreacted isoparaffin. The first hydrocarbon phase and second olefin may be contacted with a sulfuric acid feed in the second alkylation zone to form a second hydrocarbon phase, also including alkylate and unreacted isoparaffin, and the partially spent sulfuric acid that is fed to the first alkylation zone. Further, the second hydrocarbon phase may be separated, recovering an isoparaffin fraction and an alkylate product fraction.

A method for revamping a system comprising at least two ammonia production units, each unit comprising an ammonia converter each having an inlet for receiving a process gas and an outlet for releasing a purge gas, the method for revamping comprising the step of fluidly connecting the inlet of the converter of a first ammonia production unit to the outlet of the converter of a second ammonia production unit, for transporting the purge gas being produced by the converter of the second ammonia production unit, to the converter of the first ammonia production unit.
