摘要:
A heating system for a vehicle includes a reaction space (16) containing a first reactant (22) and a reactant storage space (20) containing or/and receiving a second reactant (24), wherein the first reactant and the second reactant form such a reaction system. A reaction of the first reactant with the second reactant produces a reaction product that releases heat. The second reactant can be separated from the first reactant by introducing heat into the reaction product. A reactant-releasing device (26) releases second reactant from the reactant storage space into the reaction space (16). A first heat removal device (58) removes heat from the first reactant or/and reaction product contained in the reaction space (16). A heating unit (52) heats the first reactant or/and heats the reaction product contained in the reaction space. A reactant-recirculating device (36) recirculates second reactant from the reaction space into the reactant storage space.

Related to is a system for preparing xylose liquid by continuously hydrolyzing hemicellulose, including a neutralizing unit, an acid-adjusting unit, a feeding unit, a liquefaction ejecting unit, a feed and discharge heat-exchanging unit and a discharge controlling unit. The neutralizing unit includes a raw material tank, a neutralizing concentrated sulfuric acid pump and a neutralizing pipeline mixer, the acid-adjusting unit includes an acid-adjusting concentrated sulfuric acid pump, an acid-adjusting pipeline mixer and an acid-adjusting tank, the feeding unit includes a feed tank, the liquefaction ejecting unit includes a liquefaction ejector and a liquefaction maintainer, the feed and discharge heat-exchanging unit includes a plate-type teed and discharge heat exchanger and a first discharge temperature sensor, and the discharge controlling unit includes a discharge valve and a reflux valve. The obtained xylose liquid exchanges heat with the hemicellulose liquid in the plate-type feed and discharge heat exchanger to decrease a temperature of the xylose liquid, whereas a temperature of the hemicellulose liquid is increased. Further disclosed is a method using the system. The simultaneous feed and discharge heat exchanges greatly reduce energy consumption, and feed and exchange are continuously run, thereby improving the production efficiency and simplifying manual operations.

摘要:
Energy savings in an integrated DCE/VCM plant, optionally also containing a PVC plant, is accomplished by using at least part of the vapor from a DEC quenching column to supply heat to an HCl column. The DCE plant has a high boiler column operating at superatmospheric pressure, and heat is removed from an overhead stream and used to supply heat to other portions of the process.

Integrated systems are provided for the production of higher hydrocarbon compositions, for example liquid hydrocarbon compositions, from methane using an oxidative coupling of methane system to convert methane to ethylene, followed by conversion of ethylene to selectable higher hydrocarbon products. Integrated systems and processes are provided that process methane through to these higher hydrocarbon products.
摘要:
Reactors for conducting thermochemical processes with solar heat input, and associated systems and methods. A system may include a reactor having a reaction zone, a reactant source coupled in fluid in communication with the reactant zone, and a solar concentrator having at least one concentrator surface positionable to direct solar energy to a focal area. The system can further include an actuator coupled to the solar concentrator to move the solar concentrator relative to the sun, and a controller operatively coupled to the actuator. The controller can be programmed with instructions that, when executed, direct the actuator to position the solar concentrator to focus the solar energy on the reaction zone when the solar energy is above a threshold level, and direct the actuator to position the solar concentrator to point to a location in the sky having relatively little radiant energy to cool an object positioned at the focal area when the solar energy is below the threshold level.
