摘要:
The present invention provides improved methods and apparatus for producing syngas from any carbon-containing feed material. In one aspect, a multi-zone reformer system is provided. A first reaction zone can reduce the presence of refractory tars, while a second reaction zone in communication with the first reaction zone can steam-reform methane and other components from the first reaction zone, to generate high-quality syngas suitable for conversion to liquid fuels, such as ethanol. Other embodiments employ a plurality of reaction zones for added system functionality.
摘要:
Methods and apparatus for producing alcohols from syngas are disclosed herein. In some variations, syngas is catalytically converted to methanol in a first reaction zone, and residual syngas from the first reaction zone is then catalytically converted to ethanol in a second reaction zone. Also, in some variations, syngas is catalytically converted to methanol in high yield in a first reaction zone, and the methanol is then converted (optionally, with additional syngas) to ethanol in a second reaction zone.
摘要:
A method, apparatus, and system for solar-driven chemical plant may include a solar thermal receiver to absorb concentrated solar energy from an array of heliostats. Additionally, some embodiments may include a solar driven chemical reactor that has multiple reactor tubes. The concentrated solar energy drives the endothermic gasification reaction of the particles of biomass flowing through the reactor tubes. Some embodiments may also include an on-site fuel synthesis reactor that is geographically located on the same site as the chemical reactor and integrated to receive the hydrogen and carbon monoxide products from the gasification reaction.

A method, apparatus, and system for a solar-driven chemical plant that manages variations in solar energy are disclosed. Some embodiments include a solar thermal receiver to absorb concentrated solar energy, a solar driven chemical reactor contained within the solar thermal receiver, and an entrained gas biomass feed system that uses an entrainment carrier gas and supplies a variety of biomass sources fed as particles into the solar driven chemical reactor. Inner walls of the solar thermal receiver and the chemical reactor can be made from materials selected to transfer energy. Some embodiments include a control system that may be configured to balance the gasification reaction of biomass particles with the available concentrated solar energy and additional variable parameters including, but not limited to, a fixed range of particle sizes, temperature of the chemical reactor, and residence time of the particles in a reaction zone in the chemical reactor.
