Abstract:

Abstract Hetero-element doped lithium orthosilicates have been considered as advanced tritium breeders due to the superior performances. In this work, Li4Si1−xTixO4 ceramics were prepared by proprietary hydrothermal process and multistage reactive sintering. The reaction mechanism of Li4Si1−xTixO4 was put forward. XRD and SEM analyses indicate that insertion of Ti leads to lattice expansion, which promotes the grain growth and changes the fracture mode. The compressive tests show that the crush load increases almost four times by increasing x from 0 to 0.2. However, the thermal conductivity an

Abstract:

Using cheap and porous diatomite or zeolite as silicon sources, we prepared firstly Li4SiO4 matetials for high temperature CO2 capture through solid-state method, and mainly investigated effects of silicon sources on the CO2 absorption properties of Li4SiO4 materials. Phase composition was analyzed by X-ray diffraction, and the CO2 absorption properties were studied by the simultaneous thermal thermogravimetric analyzer (TG-DSC). The results showed that Li4SiO4 materials using zeolite as silicon source showed little CO2 absorption properties, while Li4SiO4 materials using diatomite as silicon

Abstract:

Lithium silicate (Li4SiO4) material can be applied for CO2 capture in energy production processes, such as hydrogen plants, based on sorption-enhanced reforming and fossil fuel-fired power plants, which has attracted research interests of many researchers. However, CO2 absorption performance of Li4SiO4 material prepared by the traditional solid-state reaction method is unsatisfactory during the absorption/regeneration cycles. Improving CO2 absorption capacity and cyclic stability of Li4SiO4 material is a research highlight during the energy production processes. The state-of-the-art kinetic an

We have studied the structural, electronic and dynamic properties of γ- Li4SiO4(lithium orthosilicate) using density functional theory (DFT) with the generalized gradient approximation (GGA). The crystal structure is fully relaxed. The electronic band structure and Density of States (DOS) calculations indicate that γ- Li4SiO4is an insulator with an indirect band gap of 5.19 eV and it has a conduction band with the width of 5.92 eV and two valance bands with the width of 4.45 eV and 0.57 eV, respectively. In the partial DOS, Li and Si electronic densities increase more sharply than O atoms. Com

Abstract:

Lithium orthosilicate (Li4SiO4) is known to be a high temperature CO2 capture material. This work was focused on comparing Li4SiO4 to the extensively studied CaO as an adsorbent in sorption enhanced catalysis. Thermogravimetric analysis was used to study the effects of sorption temperature and compaction on Li4SiO4 using 15vol% CO2 in N2. After 2 hours of CO2 adsorption at 550°C the powder reached 35wt% uptake of CO2, corresponding to 93.6% of maximum efficiency and complete regeneration was possible at 700°C. Pressing Li4SiO4 to granular forms greatly decreased CO2 adsorption rates. Efforts t

Negli ultimi decenni è emersa l'urgenza di limitare gli impatti ambientali dovuti all'emissione di gas serra, ed in particolare della CO2. Una delle tecniche individuate per contribuire a limitare queste emissioni nel settore della produzione elettrica è la Carbon Capture and Storage (CCS). La CO2 può essere rimossa dai fumi della combustione attraverso sorbenti solidi: in un primo reattore (il carbonator) i sorbenti solidi adsorbono la CO2 dalla corrente di fumi mentre in un secondo reattore (il calciner) i sorbenti vengono rigenerati.
