Thermal and chemical utilization of carbonaceous materials, in particular for emission-free generation of energy
10450520 · 2019-10-22 · ·

A process for the generation of energy and/or hydrocarbons and other products utilizing carbonaceous materials. In a first process stage (P1) the carbonaceous materials are supplied and are pyrolysed, wherein pyrolysis coke (M21) and pyrolysis gas (M22) are formed. In a second process stage (P2), the pyrolysis coke (M21) from the first process stage (P1) is gasified, wherein synthesis gas (M24) is formed, and slag and other residues (M91, M92, M93, M94) are removed. In a third process stage (P3), the synthesis gas (M24) from the second process stage (P2) is converted into hydrocarbons and/or other solid, liquid, and/or gaseous products (M60), which are discharged. The three process stages (P1, P2, P3) form a closed cycle. Surplus gas (M25) from the third process stage (P3) is passed as recycle gas into the first process stage (P1), and/or the second process stage (P2), and pyrolysis gas (M22) from the first process stage (P1) is passed into the second process stage (P2), and/or the third process stage (P3).

All-steam gasification with carbon capture

A carbonaceous fuel gasification system for all-steam gasification with carbon capture includes a micronized char preparation system comprising a devolatilizer that receives solid carbonaceous fuel, hydrogen, oxygen, and fluidizing steam and produces micronized char, steam, volatiles, hydrogen, and volatiles at outlets. An indirect gasifier includes a vessel comprising a gasification chamber that receives the micronized char, a conveying fluid, and steam. The gasification chamber produces syngas, ash, and steam at one or more outlets. A combustion chamber receives a mixture of hydrogen and oxidant and burns the mixture of hydrogen and oxidant to provide heat for gasification and for heating incoming flows, thereby generating steam and nitrogen. The heat for gasification is transferred from the combustion chamber to the gasification chamber by circulating refractory sand. The system of the present teaching produces nitrogen free high hydrogen syngas for applications such as IGCC with CCS, CTL, and Polygeneration plants.

First stage process configurations in a 2-stage bio-reforming reactor system

Disclosed herein is an integrated plant including, in some embodiments, an interconnected set of two or more stages of reactors forming a bio-reforming reactor configured to generate syngas from wood-containing biomass. A first stage of the bio-reforming reactor is configured to cause a set of chemical reactions in the biomass to produce reaction products of constituent gases, tars, chars, and other components. The first stage includes a fluidized-bed gasifier, a fluidized-bed combustor, and a moving-bed filtration system, each of which includes media inputs and outputs to respectively receive and supply heat-absorbing media to another operation unit for recirculation in a media recirculation loop. The moving-bed filtration system includes a tar pre-reformer configured to capture and reform heavier tars into lighter tars for subsequent processing in one or more fuel-producing reactor trains. Fuel products produced by the one or more reactor trains have a biogenic content of between 50% and 100%.

Gasification with enriched oxygen for production of synthesis gas

Systems and methods are provided for producing high quality synthesis gas from a fluidized coking system that includes an integrated gasifier. Additionally or alternately, systems and methods are provided for integrating a fluidized coking process, a coke gasification process, and processes for production of compounds from the synthesis gas generated during the coke gasification. The integrated process can also allow for reduced or minimized production of inorganic nitrogen compounds by using oxygen from an air separation unit as the oxygen source for gasification. Although the amount of nitrogen introduced as a diluent into the gasification will be reduced, minimized, or eliminated, the integrated process can also allow for gasification of coke while reducing, minimizing, or eliminating production of slag or other glass-like substances in the gasifier. Examples of compounds that can be produced from the synthesis gas include, but are not limited to, methanol, ammonia, and urea.
