Abstract: A method and reactor system for depolymerizing a terephthalate polymer into reusable raw material are described, as well as a raw material obtainable by the method. The method inter alia comprises providing the polymer and a solvent such as ethylene glycol as a reaction mixture in a reactor. A heterogeneous catalyst, such as a metal containing particle, and/or a homogeneous catalyst is provided in the reaction mixture and the reaction mixture heated to depolymerize the polymer. Monomer comprising bis-(2-hydroxyethyl)-terephthalate (BHET), and 2-hydroxyethyl[2-(2-hydroxyethoxy)ethyl]terephthalate (BHEET) as byproduct are formed. The BHET is recovered from a depolymerized product stream exiting the reactor and a BHET-depleted stream is formed. A mass fraction of BHEET in the depolymerized product stream and/or in the BHET-depleted stream is monitored and adjusted to below a predetermined limit value of the BHEET-mass fraction in the depolymerized product stream.

Abstract: A method and reactor system for depolymerizing a terephthalate polymer into reusable raw material are described, as well as a raw material obtainable by the method. The method inter alia comprises providing the polymer and a solvent such as ethylene glycol as a reaction mixture in a reactor. A reusable catalyst complex comprising a catalyst entity, a metal containing nanoparticle, and a bridging moiety connecting the catalyst entity to the metal containing nanoparticle is dispersed in the reaction mixture and the reaction mixture heated to depolymerize the polymer into monomers comprising bis-(2-hydroxyethyl)-terephthalate (BHET). 2-hydroxyethyl[2-(2-hydroxyethoxy)ethyl]terephthalate (BHEET) is formed as byproduct. The BHET is recovered from the depolymerized product stream and a BHET-depleted stream is formed. A mass fraction of BHEET in the depolymerized product stream and/or in the BHET-depleted stream is monitored and, optionally, adjusted to below a predetermined limit value of the BHEET-mass fraction in the depolymerized product stream.

Abstract: A method of decomposing a feedstock gas includes introducing the feedstock gas into a mixing chamber and introducing a combustion gas into a combustion chamber connected to the mixing chamber. The combustion gas is combusted so as to produce combustion product gases. A first portion of the combustion products gases flows into the mixing chamber and mixes with the feedstock gas, and a second portion of the combustion products gases initially remains in the combustion chamber. At least some of the feedstock gas is decomposed as a result of the first portion of the combustion products gases flowing into the mixing chamber and mixing with the feedstock gas. At least some of the second portion of the combustion product gases is flowed into the mixing chamber, and the at least some of the second portion of the combustion product gases is mixed with undecomposed feedstock gas, so as to decompose at least some of the undecomposed feedstock gas.

Abstract: Control methods are disclosed for continuous, unmodulated, multiple catalytic conversion step processes using at least two catalysts, a first catalyst and a second catalyst, that accommodate changes in the performance of each catalyst and the relative performances of the catalysts. In the methods, certain process parameters are used in a manner that is indicative of changes in catalyst performance, and the control methods provide for adjustment of at least one of: the absolute amount of catalytically active species and relative amounts of each of the first catalyst and second catalyst and at least one of the rate of feed or concentration of the raw material to the reaction zone.

Abstract: A device for converting cellulose to sugar has a reaction chamber with a plurality of control components, and a control assembly. The control assembly is operatively connected to the reaction chamber, a drive assembly and control components to transmit and receive interoperability signals. The device has an inlet hopper with a detector, a crusher, an outlet hopper, a sensor assembly, a steam inlet, and a carbon dioxide inlet. The inlet hopper is configured to receive and analyze proportion data of matters in a feedstock and catalyst mixture via the detector. The crusher receives and grinds the mixture from the inlet hopper to induce chemical reaction for producing sugar. The outlet hopper is configured to determine a proportion data of matter in the grinded mixture. The control assembly is configured to determine adjustments need to be performed on the components and drive assembly to optimize the sugar production.

Abstract: A device for magnetic field-assisted simulation of zero-microgravity flame synthesis of nanoparticles includes a gradient magnetic field device, a combustor and a product collection device. The gradient magnetic field device is composed of two magnetic field devices arranged face to face. The combustor is located between the two magnetic field devices. The outlet of the combustor is vertically upward. The position is below the magnetic field center of the gradient magnetic field device. The body force acting on the flame and surrounding magnetic species thereof by the gradient magnetic field device counteracts the gravitational buoyancy lift effect, so that flame synthesis is carried out under a simulated zero/microgravity flame to prepare the nanoparticles. The device is able to use a gradient magnetic field to simulate the zero/microgravity flame on the ground to synthesize the nanoparticles under special flame characteristics, with reduced flame disturbance, improved stability, and no overheated region.
