摘要： A method of retorting oil shale is provided, comprising: continuously feeding oil shale into a retorting unit; heating the retorting unit using renewable electrical energy; converting the oil-shale kerogen into kerogen oil; conveying a cross-flow sweep gas across a moving bed of the oil shale, to carry the kerogen oil out of the retorting unit; recovering the kerogen oil; and recovering spent oil shale. The combination of electrical heating and cross-flow retorting achieves uniform heating to optimize the production of hydrocarbons. A system for retorting oil shale is also provided, comprising: a retorting unit; an inlet for continuously feeding oil shale; electrical-energy elements within the retorting unit; an inlet for conveying a cross-flow sweep gas through the retorting unit; and an outlet for the cross-flow sweep gas carrying the kerogen oil. The principles of the invention may be applied to ex situ systems, in situ systems, or hybrid systems.

摘要： The present disclosure relates generally to a two-stage biomass pyrolysis processes that maximize pyrolysis vapor yield from a lignocellulosic biomass while being conducive to commercial-scale throughput of biomass. A lignocellulosic feedstock is first pyrolyzed in a reactor first stage comprising at least one auger at a temperature and residence time that produces pyrolysis vapors derived predominantly from cellulose and hemi-cellulose fractions of the feedstock. Partially-pyrolyzed feedstock from the reactor first stage is then pyrolyzed in a reactor second stage at a higher temperature for an additional residence time to produce additional pyrolysis vapors that are predominantly derived from lignin. Certain embodiments arrange multiple reactor first stages around a single reactor second stage.

摘要： Methods, devices and systems for continuously converting biomass are described herein. A device has a feed section for holding a moving bed of biomass, namely wood, having a drying section, a flame zone for degassing, and a, smolder zone for carbonizing the biomass into a solid converted product, namely charcoal. The device includes a tank for collecting the solid converted product arranged below a grate and coupled with the feed section in a gas-tight manner. The system comprising the device, a biogas plant and/or a combined heat and power plant conveys the liquid converted product, namely pyroligneous acid or acetic acid, to the biogas plant and/or the solid converted product, namely charcoal, to the combined heat and power plant.

摘要： A biomass torrefaction system is provided which enables a continuous torrefaction process that involves the introduction of biomass particles into a rotating reactor drum having a low oxygen environment. The particles are conveyed through the drum by a heated gas stream and simultaneously torrefied thereby. Gas exiting the drum is recirculated back to a heat source for reheating the gas prior to reentering the drum. A method of biomass torrefaction is also provided.

摘要： A retort oven for decomposition of waste materials through pyrolysis employing a deck with a variable angle of inclination for adjusting the retention time and processing rate of waste material flowing unassisted through the oven interior. The oven includes an outer shell lined with a refractory material and houses an inner oven chamber. The deck is adjustably hinge mounted to the inner chamber supporting sidewalls extending in a decline from a waste material entrance to a charred material exit. The deck is operated in a preferred angle range of inclination between 28°-50° from the oven floor normal. A controlled heat source is positioned within the oven to heat a first outer volume whose heated gases are transferred into a second inner volume of the inner chamber using an array of heat gun tubes heating the deck and material as it descends along the declined deck. The deck can be adjusted for varying the retention time of material within the oven for varied exposure to heat and charring efficiency.
