In this work, corn starch (St) was firstly grafted with polyacrylamide (PAM) to obtain StAM, which subsequently immobilized arginine a guanidine-containing starch-based resin, StAM-Arg. The synthesized products were characterized via Fourier transform infrared spectroscopy (FT-IR), 13C-NMR nuclear magnetic resonance (13C-NMR), scanning electron microscopy (SEM), X-ray diffraction (XRD), gel permeation chromatography (GPC), photoelectron (XPS) and thermogravimetric analysis (TGA). StAM-Arg...
Abstract Land use change, tillage practices and straw incorporation are known to affect soil organic carbon (SOC) as well inorganic (SIC) turnover in agricultural soils. SOC SIC, particularly pedogenic carbonates (PC), were assessed a semi‐humid region of China depth 160 cm. δ 13 C values used calculate the percentage PC lithogenic (LC) total SIC. Over 39‐y period intensive agriculture including 14 y × experiment, three treatments, i.e ., with wheat maize return (TWM), (TW), no‐tillage (WM)...
The sinter process of iron ore with biomass carbon instead coke breeze as fuel was investigated via thermodynamic analysis in this paper through a comparison composition indexes, metallurgical properties, and pollutant emissions. Straw charcoal used paper, its replacement does not adversely affect the index ore, namely Fe, FeO, basicity, S, nor reduction degradation index. However, has great effect on emissions gases, including SO2, NOx, CO, CO2. result shows that gases produced...
Abstract In this article, the bifunctional NiO/CaO@C12A7 catalysts having reforming catalytic effect and CO 2 adsorption were prepared with co‐precipitation method, used in sorption‐enhanced steam process of tar from RCOG for hydrogen production. Among six kinds samples different load ratios, catalyst CaO:C12A7:NiO ratio 70:15:15 showed best performance to produce H as well excellent characterization. Under action catalyst, yield obtained 1‐methylnaphthalene (C 11 10 ) model compound higher...
The utilization of biomass can not only alleviate the energy crisis but also reduce pollution fossil fuels to environment. Biomass gasification is one main methods, which effectively convert into high-value and wide-use gas. However, this process inevitably produces by-product tar, affects yield syngas. In order solve problem, a two-stage combining pyrolysis CO2 catalytic reforming proposed in paper, used prepare high calorific value syngas rich H2 CO tar while realizing resource CO2....
Abstract From the thermodynamic analysis of steam reforming process raw coke oven gas, H 2 amplification factor after can reach highest (over 3.5) in temperature range between 650 and 800°C, where bifunctional catalysts to be prepared should have best CO adsorption performances as well excellent catalytic performances. In this article, NiO/CaO@C12A7 were at different preparation parameters, among them, catalyst sample calcination 1,000°C time 4 h with co‐precipitation (CP) method showed...
The double-effect Ni-based catalysts, modified with Ce, Mg, and Fe synthesized by the coprecipitation method, were applied into enhanced steam reforming process of real tar. effects catalysts different doping mass proportions (3, 6, 9, 12%) on H 2 yield, CO concentrations studied. results revealed that tar efficiency was improved appropriate additives added. Ce- or Mg-doped catalyst could change distribution morphology active component Ni. 6% Ce 3% Mg showed best catalytic activity in...
Variation laws of growth conditions and root cortical aerenchyma (RCA) 15 common maize hybrids (Zea mays L.) in Yunnan Province under simulated rare extreme drought rehydration were tested this paper.The relationship between functions tissues process resilience after was discussed.Results demonstrated: 1) middle period, RCA area is closely related with resistance varieties 2) Varieties large or small stress have poor rehydration, while present strong resilience.We concluded that formed will...
Abstract Organic substitution management (OSM) is critical for soil conservation and nitrogen efficiency. However, integrated assessment of quality crop productivity under paddy‐upland rotation systems after OSM introduction still lacking. Here, nitrogen‐related properties use efficiency (NUE) were evaluated in 2018, 2019, 2020, based on a long‐term rice‐fava bean experiment started 2015. In comparison to chemical fertilization, increased total (TN) available (AN) by 13.1% 13.8%,...
