Synthesis of methanol from recirculated CO2 and H2 produced by water electrolysis allows sustainable production fuels chemical storage energy. Production renewable has, however, not achieved commercial breakthrough, novel methods to improve economic feasibility are needed. One possibility is alter the reaction route using catalytic alcoholic solvents, which makes process possible at lower temperatures. To estimate techno-economic potential this approach, feasibilities conventional gas-phase...
Sorption enhanced synthesis has been previously shown to improve carbon dioxide hydrogenation methanol by mitigating the thermodynamic limitations. This work investigates efficiency of via sorption focusing on determining optimal process parameters. The study is based upon a fully dynamic experimentally validated model which extended account for adsorbent regeneration, downstream product separation and recirculation unreacted gases. An additional reactor configuration with guard layer...
Plastics are essential materials for modern societies, but their production contributes to significant environmental issues. Power-to-X processes could produce plastics from captured CO2 and hydrogen with renewable electricity, these technologies may also face challenges perspective. This paper focuses on sustainability assessment of CO2-based low-density polyethylene (LDPE) compared bio-based LDPE. Life cycle has been applied study climate impacts land use related biodiversity different...
In order to limit climate change, fast greenhouse gas reductions are required already before 2030. Ethanol commonly produced by fermentation of sugars derived either from starch-based raw material such as corn, or lignocellulosic biomass is an established fuel decarbonizing the transport sector. We present a novel selective and flexible process concept for production ethanol with electricity main inputs. The consists several consecutive steps. First synthesis gasification purified filtration...
The ambitious CO2 emission reduction targets for the transport sector set in Paris Climate Agreement require low-carbon energy solutions that can be commissioned rapidly. production of gasoline, kerosene, and diesel from renewable methanol using methanol-to-olefins (MTO) Mobil’s Olefins to Gasoline Distillate (MOGD) syntheses was investigated this study via process simulation economic analysis. current work presents a model comprising liquid fuel heat integration. According analysis, total...
This research work presents the integration of polypropylene hollow fiber membrane contactor–based CO2 absorption unit using aqueous sodium hydroxide (NaOH) as absorbent solution, and precipitation high-quality calcium carbonate by addition chloride. The integrated crystallization process bypasses need for cost-intensive energy regeneration solution. Given lifetime high added value precipitated carbonate, proposed approach integrating solid particle formation a carbon dioxide mitigation...
The chemical industry needs new methods for sourcing carbon-containing feedstocks from renewable sources to decrease CO 2 emissions and reduce reliance on fossil fuels. Ethylene, a crucial base used making polymers ethylene oxide, is primarily produced through steam cracking of feedstocks. However, an evolving technology the electrochemical reduction or produce ethylene. study assesses environmental, economic energetic performance biomass-based process that produces based CO. results are...
