摘要： The invention relates to a method for separating gases which comprises: a first step in which a gas fuel stream comprising combustible substances that produce gas products when oxidised, and an oxygen-rich inlet stream are passed through at least two modules of oxygen-separating ceramic membranes, such that the two streams come into contact through the membranes and exchange heat; a second step of selective diffusion of oxygen from the oxygen-rich stream to the fuel stream, such that the outlet streams from the membrane modules are an oxygen-depleted or completely oxygen-free stream and a partially or completely oxidised stream; and a third step of recovery of at least two separate outlet streams of at least two gases selected from oxygen, nitrogen, carbon dioxide and hydrogen.

摘要： A method of producing advanced carbon materials can include extracting a coal sample from a location, performing a spectral analysis on the coal sample, determining one or more desired advanced carbon materials based at least in part on spectral analysis, extracting an amount of coal from the location, beneficiating the amount of coal, and processing the beneficiated amount of coal to produce the one or more desired advanced carbon materials from at least some of the amount of coal.

摘要： The present invention relates to a biomimetic-hybrid solvent system for simultaneous capture of H2S and CO2 from any gaseous composition. The present invention also relates to a process for upgradation of biogas to bio CNG by removing gaseous contaminants, including microbial removal of H2S, to obtained purified CO2. The biomimetic-hybrid solvent system contains three components selected from tertiary amine compounds, a functional colloidal fluid, and an enzyme mimic.

摘要： The present invention provides a process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; sequentially removing ammoniacal, sulphurous and carbon dioxide impurities from the raw synthesis gas to form desulphurised gas and recovering carbon dioxide in substantially pure form; converting at least a portion of the desulphurised synthesis gas to a useful product. Despite having selected a more energy intensive sub-process i.e. physical absorption for removal of acid gas impurities, the overall power requirement of the facility is lower on account of lower steam requirements and thereby leading to a decrease in the carbon intensity score for the facility.

摘要： A hydrocarbon is reacted with water in the presence of a catalyst to form hydrogen, carbon monoxide, and carbon dioxide. Hydrogen is selectively allowed to pass through a hydrogen separation membrane to a permeate side of a reactor, while water and carbon-containing compounds remain in a retentate side of the reactor. An outlet stream is flowed from the retentate side to a heat exchanger. The outlet stream is cooled to form a cooled stream. The cooled stream is separated into a liquid phase and a vapor phase. The liquid phase is flowed to the heat exchanger and heated to form steam. The vapor phase is cooled to form condensed water and a first offgas stream. The first offgas stream is cooled to form condensed carbon dioxide and a second offgas stream. The steam and the second offgas stream are recycled to the reactor.

摘要： A reduction device, an acid gas recovery device, a recovery device collector, and a first removed substance returning line are provided. The reduction device is configured to perform a reduction process to turn iron oxide to reduced iron by adding a reducing agent. The acid gas recovery device is configured to recover CO2 being acid gas with CO2 absorbing liquid being acid gas absorbing liquid from exhaust gas containing at least powder-shaped iron-based solid substances and the acid gas, which are discharged from the reduction device. The recovery device collector is configured to collect the iron-based solid substance contained in the absorbing liquid with a filter. The iron-based solid substances collected by the recovery device collector are removed, and removed substances containing the removed iron-based solid substances are returned to the reduction device side through the first removed substance returning line.

摘要： The present disclosure provide for methods of reforming a hydrocarbon such as methane. In an aspect, when the method is driven via renewable energy (e.g., use of solar energy, wind energy, or other renewable energy) and coupled with zero-energy input product gas separation, this enables the capture of pure CO2 (i.e., carbon sequestration) and carbon-neutral utilization of methane can be achieved. As a result, the present disclosure can provide for a method to reform methane with zero-energy input product gas separation.

摘要： In a process for separating carbon dioxide from a waste gas (3) of a fluid bed catalytic cracking installation (1) containing carbon dioxide, nitrogen and possibly carbon monoxide, the waste gas (3) is separated by adsorption to form a gas enriched in carbon dioxide and depleted in nitrogen (29) and a gas rich in nitrogen and depleted in carbon dioxide (31), and at least a portion of the gas enriched in carbon dioxide and depleted in nitrogen is separated in a separation device (30) by way of separation at a temperature of less than 0° C. by partial condensation and/or by distillation to form a fluid rich in carbon dioxide (35) and a fluid depleted in carbon dioxide (37).
