A system for processing solid waste including a segmented gasifier having a first segment detachably connected to a second segment, and a burner positioned downstream of the segmented gasifier and coupled to the segmented gasifier. A process for treating solid waste including introducing the solid waste into a first end of a segmented gasifier having a first segment detachably connected to a second segment. Gasifying the solid waste as it traverses from the first end of the gasifier to a second end of the segmented gasifier, and producing a gaseous output and a solid output at the second end of the segmented gasifier. Separating the gaseous output and the solid output, and introducing a portion of the gaseous output to a burner and recycling a portion of the gaseous output to the segmented gasifier as an energy source.

A methanol synthesis plant comprising: a feed pretreating section operable to pretreat a feed stream; a synthesis gas (syngas) generation section comprising one or more reactors operable to produce a syngas synthesis product stream comprising synthesis gas from the feed stream; a methanol synthesis section comprising one or more methanol synthesis reactors operable to produce a synthesis product comprising methanol; and/or a methanol purification section operable to remove at least one component from the synthesis product to provide a purified methanol product; wherein the methanol synthesis plant is configured such that, relative to a conventional methanol synthesis plant, more of the net energy required by the methanol synthesis plant, the feed pretreating section, the syngas generation section, the methanol synthesis section, the methanol purification section, or a combination thereof, is provided by a non-carbon based energy source, a renewable energy source, and/or electricity.

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

Reactors and systems for producing fuel gases are provided herein. In some embodiments, the reactor comprises: an outer sleeve, and inner reaction tube received within the outer sleeve, and an induction heater comprising an induction coil wrapped around the outer sleeve, wherein the induction coil is approximately the same length as the inner reaction tube and longitudinally aligned with the inner reaction tube. Systems including the reactor can be modular such that they can be installed on site at fuel stations and other locations. Related methods for making a fuel gas are also provided.

The present invention relates to energy storage systems and reactors useful in such systems. Inventive reactors comprise a reaction vessel defining an inner volume and a compensation element, whereby said inner volume is filled with a fixed bed that is essentially free of cavities and that comprises particles of formula (I), FeOx (I), where 0≤x≤1.5; said compensation element is adapted to adjust said inner volume. The reactors are inherently explosion—proof and thus suited for large scale use. The systems are useful for compensating long-term fluctuations observed in production of renewable energy.

There are provided systems and methods for using fuel-rich partial oxidation to produce an end product from waste gases, such as flare gas. In an embodiment, the system and method use air-breathing piston engines and turbine engines for the fuel-rich partial oxidation of the flare gas to form synthesis gas, and reactors to convert the synthesis gas into the end product. In an embodiment the end product is methanol.

Methods and systems for processing construction and demolition (C&D) materials to produce a product gas stream and/or electricity are disclosed herein. In some embodiments, the method comprises pre-processing C&D materials to produce a C&D feed, and processing the C&D feed to produce syngas. The C&D feed can comprise untreated wood, treated wood, paper and cardboard, yard waste, plastic, rubber, and/or foam. Processing the C&D feed can comprise gasifying the C&D feed, steam, and oxygen in a gasifier at a temperature of no more than 950° C. and/or a pressure of no more than 200 psi to produce syngas.

The present invention provides a blended fuel and methods for producing the blended fuel, wherein a low carbon fuel derived from a renewable resource such as biomass, is blended with a traditional, petroleum derived fuel. A blended fuel which includes greater than 10% by volume of low carbon fuel has an overall improved lifecycle greenhouse gas content of about 5% or more compared to the petroleum derived fuel. Also, blending of the low carbon fuel to the traditional, petroleum fuel improves various engine performance characteristics of the traditional fuel.
