Biogas upgrading and utilization is a novel technology to obtain resource-efficient vehicle fuel. In this study, mass transfer model for CO2 absorption from biogas into potassium argininate (PA) solutions was developed. The computational fluid dynamics (CFD) methods were employed solve the differential equations in three domains of membrane contactor. simulations focused on characteristics both gas absorbent phases demonstrate concentration distributions axial radial directions module....
Combustion characteristics and thermal dynamic of blends inferior coal core plywood under different oxygen-enriched atmospheres were investigated using thermogravimetric (TG) analysis. According to the results, with increasing oxygen concentration, TG DTG curves tended move a lower temperature region. The comprehensive combustion characteristic index SM was first proposed in this work, suggesting that enriched concentration can significantly improve conditions. Apparent activation energies...
Chemical looping hydrogen production is a kind of technology with great potential. NiFe2O4 one the oxygen carriers best comprehensive performance, but carrier still has disadvantages low and poor reaction stability. In this paper, small amount Ce was doped in to improve efficiency. And stability improved by loading an inert carrier. The experimental results showed that 6 wt% Ce-NiFe2O4 had highest H2 yield, yield per unit mass increased from 194 367 mL/g. Thermodynamic simulation...
In the chemical looping hydrogen generation process, CoFe2O4 is regarded as one of most excellent candidates for oxygen carriers (OCs). this paper, synergistic effect Cu and Ce added to was studied. The doping improved reactivity with methane, also increased yield purity. results indicated that introduction facilitated deep reduction CoFe2O4, which ascribed enhanced migration capacity lattice oxygen. addition, addition inhibited decomposition CH4 alleviated carbon deposition. Cu4Ce4-CoFe had...
Summary In the research of biomass chemical looping gasification technology, production hydrogen‐rich synthesis gas has received increasing attention. this paper, iron‐nickel oxygen carriers were prepared by mechanical and impregnation method. Chemical experiments performed with pine sawdust in a self‐built fixed‐bed reactor to prepare gas. Experimental results showed that for carrier loading ratio 3% NiO under reaction conditions 800°C, steam content (S/B) 1.25, lattice (O/B) 0.2, volume...
Combustion experiments were performed in a bubbling bed combustor to explore the effects of various oxygen concentrations (21% 40%), temperatures (850 °C 950 °C), and mixing ratios (0% 30%) on formation NO gas. In order correspond different combustion stages, generated distinguished as volatile-NO coke-NO, respectively, total amount conversion rate analyzed. The results indicated that comes mainly from fixed carbon combustion, an increased concentration environment could produce more during...
The CaO-based sorbent is considered to be a potential candidate for high-temperature CO2 capture. However, its application limited by the loss in sorption activity with increasing number of calcium looping (CaL) cycles, which leads vast spent sorbents pollution. To solve problem, optimized utilization through novel process achieve sequential capture and SO2 retention studied work, sulfation pattern CaO coming from CaL under different variables investigated. It observed that experiencing...
In this study, Ce-modified BaFe2O4 prepared by the sol–gel method was subjected to batch gasification experiments in a fixed bed. The effects of temperature (T), steam-to-biomass ratio (S/B), oxygen supply coefficient (α), and Ce loading on performance were explored. optimal carrier selected as 6 wt % (6Ce-BF).

In 2021, a questionnaire investigation conducted mainland using multi-stage sampling approach. After statistical description, logistic regression used analyze considering safety. rate 96.61%. Of these, 65.84% considered be essential, while 58.72% prioritized efficacy....
The control of anthropogenic CO2 emissions has attracted worldwide attention because global warming. Among diverse carbon capture technologies, calcium looping (CaL) is proposed as a favorable approach for postcombustion mitigation. However, the sorbents' capacitive loss with increased CaL cycling severely limited efficient application method. Therefore, obtaining sintering-resistant Ca-based sorbents high capacity, fast kinetics, and superior stability considered research priority. Here, we...
