Development of catalytic combustion and CO2 capture and conversion technology

Abstract

Changes are needed to improve the efficiency and lower the CO2 emissions of traditional coal-fired power generation, which is the main source of global CO2 emissions. The integrated gasification fuel cell (IGFC) process, which combines coal gasification and high-temperature fuel cells, was proposed in 2017 to improve the efficiency of coal-based power generation and reduce CO2 emissions. Supported by the National Key R&D Program of China, the IGFC for near-zero CO2 emissions program was enacted with the goal of achieving near-zero CO2 emissions based on (1) catalytic combustion of the flue gas from solid oxide fuel cell (SOFC) stacks and (2) CO2 conversion using solid oxide electrolysis cells (SOECs). In this work, we investigated a kW-level catalytic combustion burner and SOEC stack, evaluated the electrochemical performance of the SOEC stack in H2O electrolysis and H2O/CO2 co-electrolysis, and established a multi-scale and multi-physical coupling simulation model of SOFCs and SOECs. The process developed in this work paves the way for the demonstration and deployment of IGFC technology in the future.

Advances in Enhancing the Stability of Cu-Based Catalysts for Methanol Reforming

“…According to the continuous efforts of researchers, the main factors that affect the deactivation of copper-based catalysts are summarized as follows: (1) The interaction of the active metal and support forms an alloy, which leads to the deactivation [63,64]. Then, the alloying process reduces the adsorption of relevant reactants.…”

“…With the booming economy, energy consumption and harmful gas emissions have increased sharply [1][2][3], and the decline of fossil fuels has become a major obstacle to sustainable development. With the needs of global sustainable development, we urgently need some new fuels.…”

Improving the performance for direct electrolysis of CO2 in solid oxide electrolysis cells with a Sr1.9Fe1.5Mo0.5O6−δ electrode via infiltration of Pr6O11 nanoparticles

“…The innovation in CO 2 emission reduction and energy conversion technologies has attracted increasing attention from governments and industries due to the severe environmental problems caused by fossil fuel consumption. 1,2 Converting carbon dioxide into a variety of chemicals and high-value fuels can effectively mitigate these global energy security and environmental problems. Electrochemical CO 2 reduction reaction (CO 2 RR) using solid oxide electrolysis cells (SOECs) can directly convert CO 2 to CO at the cathode while producing O 2 at the anode at an external voltage.…”

Confinement effects over Ni-based catalysts for methane dry reforming

“…3,4 CO 2 catalytic conversion technology is a method of utilization that can convert CO 2 into high value-added fuels and chemicals. [5][6][7] Among them, dry reforming of CH 4 and CO 2 can simultaneously transform two greenhouse gases together to syngas (a mixture of CO and hydrogen), and the molar ratio of the product CO : H 2 is close to 1, which can be directly used for the Fischer-Tropsch reaction to synthesize high-value fuels and chemicals. [8][9][10][11][12][13] It can also be used as an effective technical route to obtain clean hydrogen energy.…”
