Накратко на български

Никелеви катализатори от порест силиций се разработват за превръщане на въглеродния диоксид и метана в синтез газ (смес от водород и въглероден моноксид). Това помага за намаляване на вредните емисии и създаване на полезни химикали за чиста енергия.

Design of low-cost and carbon-resistant Ni-based mesoporous silicas for chemical CO2 utilization through tri-reforming of methane

The EU-funded Marie Skłodowska-Curie Individual Fellowship, MesoSi-CO2 project, aimed to design low-cost and carbon-resistant nickel-based mesoporous silicas for chemical CO2 utilization through tri-reforming of methane. This research targeted at developing an efficient synthesis route for KIT-6 mesoporous silica by taking advantage of renewable bio-sources, zero-cost waste, and microwave technology. Reforming of methane is one of the most vital industrial processes which converts natural gas into synthesis gas/syngas (a mixture of H2 and CO). Syngas is an important building block for transforming carbon-based feedstock into hydrocarbons and hydrogen for fuel cells. The advantage of the studied process is the production of value-added products which is essential to complete the carbon cycle (from hydrocarbons to CO2, then back to carbon-containing chemicals). The usage of CO2 as a valuable resource will lead to creation of new economies with high potential of job creation, as well as business competitiveness for using and proposing clean energy sources. These aspects support the perspective that all sectors should employ low-pollution renewable energy with net “zero-emission” of CO2. Additionally, it is necessary to combat future CO2 emissions to prevent nature changes, such as global temperature increase, melting glaciers and extinction of animal species. The overall aim of this MSCA-IF project was to design Ni-containing KIT-6 catalysts for tri-reforming of methane, leading to conversion of CO2 during electricity generation and production of value-added products, such as H2 and CO (synthesis gas). The Scientific Objectives (SO) were: SO1: Synthesis of catalysts with new properties for CO2 utilization: novel synthesis routes were proposed by involving industrial waste of rice husk ash and microwave usage. SO2: Control of new properties by physicochemical characterization techniques: XRF, SAXS, XRD, N2 sorption, TPR-H2, TPD-CO2, TPD-NH3, H2 chemisorption, TGA/DSC-MS, SEM to determine the suitable conditions for preparation of the catalysts. In situ XAS-XRD was utilized to understand the course of reduction. SO3: Evaluation of catalytic performance in reforming of methane reactions for CO2 transformation to synthesis gas: understanding of catalysts activation and obtained selectivity. In situ XAS-XRD analyses were carried out to investigate a possible cause of catalyst deactivation (carbon formation, sintering, oxidation of metallic nickel).

Цел на проекта

Increasing carbon dioxide (CO2) concentrations in our atmosphere are becoming evident and are having a tremendous effect on the global temperature rise. Growing awareness of greenhouse gas emissions has led to the implementation of chemical CO2 utilization technologies. Tri-reforming of methane (TRM) can not only produce synthesis gas (CO + H2) with desired H2/CO ratios (1.5–2.0) but can also eliminate carbon formation which is a serious problem in reforming of methane. Moreover, TRM allows converting CO2 directly from flue gases when applied in natural gas-fired power plants. However, a lack of catalysts able to operate efficiently with sufficient long-term stability hinders the development of the process. In this project, the proposed solution is to design a Ni-based mesoporous silica resistant to sintering and carbon formation and able to perform superior catalytic conversion of CO2. The synthesis of catalysts takes advantage of renewable bio-sources, zero-cost industrial waste and assistance of microwaves. The latter is applied to reduce power usage. The catalytic measurements will be performed with gas composition typical of flue gases from a natural-gas-fired power plant. The materials will be characterized by methods dedicated to examine physico-chemical features, such as XRD, N2 sorption, TPR, H2 chemisorption, TGA/DSC-MS, and XPS. The catalysts with optimal properties will be studied by steady-state isotopic transient kinetic analysis (SSITKA). Moreover, density functional theory (DFT) will be carried out to support the experiments. The understanding of possible deactivation mechanisms (carbon formation, sintering, selectivity towards side reactions) will be studied during the Secondment stay (Sorbonne Université, France). Operando XAS-XRD measurements will be performed to reveal the nature of active sites on the tri-reforming catalysts.
