Currently, the cost of electricity for electrolysis producing hydrogen is about 70–90% total cost. Scientists predict that share renewable energy in expected to reach 70% 2050, as wind photovoltaic power generation China low 0.13¥/(kW·h), and use sources, mainly power, can effectively reduce electricity. Meanwhile, with improvement technology, an electrolyzer used proton exchange membrane production technology be reduced by 50%, which will more than 20%. According distribution resources each...

The moisture content of biomass (biomass MC) is related to the costs power plants and affects efficiency boiler. Online monitoring MC will be beneficial for combustion control fuel management. In this study, dimensions crushing height near-infrared (NIR) spectrum acquisition on a plant conveyor belt were simulated in an experimental setup.

Fabrication of p-n heterojunction materials is an efficient strategy for improving the photocatalytic activity by suppressing recombination photogenerated electrons and holes. In this study, a consisting Cu₂O In₂O₃ was synthesized using hydrothermal in situ deposition method. The Cu₂O/In₂O₃ hybrid exhibited enhanced performance hydrogen evolution reaction degradation organic pollutants compared with pure In₂O₃. sensitization considerably light response hybrid, close contact between led to...

The corrosion of refractories by sodium salts in waste liquid at high temperature has become a serious problem. This paper focuses on the thermodynamic characterization carbonate (Na₂CO₃) six FactSage modelling combination with X-ray diffraction (XRD). Three are oxides (Fe₂O₃, Al₂O₃, and Cr₂O₃), other three synthetics spinels (magnesium chromium, MgO·Cr₂O₃; magnesioferrite, MgO·Fe₂O₃; and, magnesium aluminium, MgO·Al₂O₃). First, simulations were carried out thermodynamics model using...

As a kind of renewable resource, biomass has been used more and widely, but the potassium contained in can cause corrosion refractory. For better understanding thermodynamic mechanisms, five components common refractory materials (magnesium chrome spinel MgO·Cr₂O₃, magnesium aluminum MgO·Al₂O₃, Al₂O₃, MgO, Cr₂O₃) with salts (K₂CO₃, K₂SO₄, KCl) under high-temperature were studied by using FactSageTM 7.0 software. Thermodynamic calculation results indicate that MgO is best resistance...

Abstract A simple, green, and efficient mechanochemical approach was developed herein to prepare tunable magnetic graphene oxide nanoparticles. The obtained nanoparticles were successfully used as adsorbents in a dispersive solid‐phase extraction method extract three cationic dyes (i.e., thioflavine T, auramine‐O, basic orange 2) found food samples. Our proposed also utilized high‐performance liquid chromatography with ultraviolet detection. Several key variables affecting the recovery...

This paper presents the melting temperature (MT) and energy consumption (EC) of model municipal solid waste incineration (MSWI) fly ash (FA) under influence calcium oxide (CaO), silicon dioxide (SiO 2 ), aluminium (Al O 3 ) boron (B based on thermochemistry simulations. Nine different base-to-acid ratios (B/A) raw FA have been explored.
