摘要:
A multiple stage synthesis gas generation system is disclosed including a high radiant heat flux reactor, a gasifier reactor control system, and a Steam Methane Reformer (SMR) reactor. The SMR reactor is in parallel and cooperates with the high radiant heat flux reactor to produce a high quality syngas mixture for MeOH synthesis. The resultant products from the two reactors may be used for the MeOH synthesis. The SMR provides hydrogen rich syngas to be mixed with the potentially carbon monoxide rich syngas from the high radiant heat flux reactor. The combination of syngas component streams from the two reactors can provide the required hydrogen to carbon monoxide ratio for methanol synthesis. The SMR reactor control system and a gasifier reactor control system interact to produce a high quality syngas mixture for the MeOH synthesis.

摘要:
Various processes and apparatus are discussed for an ultra-high heat flux chemical reactor. A thermal receiver and the reactor tubes are aligned to 1) absorb and re-emit radiant energy, 2) highly reflect radiant energy, and 3) any combination of these, to maintain an operational temperature of the enclosed ultra-high heat flux chemical reactor. Particles of biomass are gasified in the presence of a steam carrier gas and methane in a simultaneous steam reformation and steam biomass gasification reaction to produce reaction products that include hydrogen and carbon monoxide gas using the ultra-high heat flux thermal energy radiated from the inner wall and then into the multiple reactor tubes. The multiple reactor tubes and cavity walls of the receiver transfer energy primarily by radiation absorption and re-radiation, rather than by convection or conduction, to the reactants in the chemical reaction to drive the endothermic chemical reaction flowing in the reactor tubes.

A desktop includes a first portion, a second portion, and a linkage assembly attached to the first and second portions. The first desktop portion has a first, substantially planar, upper surface, and an edge. The second desktop portion has a second, substantially planar, upper surface, a proximal edge, and a distal edge. The linkage assembly is configured such that the second desktop portion is movable between a first configuration and a second configuration. At the first configuration, the second desktop portion is substantially coplanar with the first desktop portion, and the proximal edge of the second desktop portion is adjacent the edge of the first desktop portion. At the second configuration, the proximal edge of the second desktop portion is beneath the edge of the first desktop portion, and the second desktop portion is not coplanar with the first desktop portion and is not parallel to the first desktop portion.
摘要:
A method, apparatus, and system for a solar-driven bio-refinery that may include a entrained-flow biomass feed system that is feedstock flexible via particle size control of the biomass. Some embodiments include a chemical reactor that receives concentrated solar thermal energy from an array of heliostats. The entrained-flow biomass feed system can use an entrainment carrier gas and supplies a variety of biomass sources fed as particles into the solar-driven chemical reactor. Biomass sources in a raw state or partially torrified state may be used, as long as parameters such as particle size of the biomass are controlled. Additionally, concentrated solar thermal energy can drive gasification of the particles. An on-site fuel synthesis reactor may receive the hydrogen and carbon monoxide products from the gasification reaction use the hydrogen and carbon monoxide products in a hydrocarbon fuel synthesis process to create a liquid hydrocarbon fuel.

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.

A mat includes a mat body defining an upper surface dimensioned for a user to stand on the upper surface. The upper surface is non-planar and includes at least one terrain feature defining the non-planarity. The terrain feature has a size that is on the order of magnitude of the size of the user's foot. Presenting this surface to the user may help remind him or her to move his or her feet to thereby adopt multiple poses, thereby preventing the user from maintaining any single pose for a fatigue-inducing duration.

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.
摘要:
A method, apparatus, and system for an integrated solar-driven chemical plant that manages variations in solar energy are disclosed. In some embodiments, a chemical reactant, including particles of biomass, are converted in a solar driven chemical reactor into synthesis gas containing carbon monoxide and hydrogen using concentrated solar energy to drive the conversion of the chemical reactant. The synthesis gas is supplied for a catalytic conversion of the synthesis gas in a methanol synthesis plant to methanol. Cycling occurs between an operational state and an idle state for a number of methanol trains in the methanol synthesis plant depending upon an amount of synthesis gas generated in the solar driven chemical reactor. A control system for the chemical reactor sends control signals to and receives feedback from a control system for the methanol synthesis plant.
