Screening of MgO- and CeO_2-Based Catalysts for Carbon Dioxide Oxidative Coupling of Methane to C_(2+) Hydrocarbons

引用

Journal of natural Gas Chemistry 2004年第1期13卷 23-35页

作者： Istadi Nor Aishah Saidina Amin chemical Reaction engineering Group(CREG) Faculty of Chemical and Natural Resources EngineeringUnivevsiti Teknologi MalaysiaUTM SkudaiJohor Bahru81310 Malaysia

The catalyst screening tests for carbon dioxide oxidative coupling of methane (CO2-OCM) have been investigated over ternary and binary metal oxide catalysts. The catalysts are prepared by doping MgO- and CeO2-based solids with oxides from alkali (Li2O), alkaline earth (CaO), and transition metal groups (WO3 or MnO). The presence of the peroxide (O2-2) active sites on the Li2O2, revealed by Raman spectroscopy, may be the key factor in the enhanced performance of some of the Li2O/MgO catalysts. The high reducibility of the CeO2 catalyst, an important factor in the CO2-OCM catalyst activity, may be enhanced by the presence of manganese oxide species. The manganese oxide species increases oxygen mobility and oxygen vacancies in the CeO2 catalyst. Raman and Fourier Transform Infra Red (FT-IR) spectroscopies revealed the presence of lattice vibrations of metal-oxygen bondings and active sites in which the peaks corresponding to the bulk crystalline structures of Li2O, CaO, WO3 and MnO are detected. The performance of 5%MnO/15%CaO/CeO2 catalyst is the most potential among the CeO2-based catalysts, although lower than the 2%Li2O/MgO catalyst. The 2%Li2O/MgO catalyst showed the most promising C2+ hydrocarbons selectivity and yield at 98.0% and 5.7%, respectively.

The impact of land afforestation on carbon stocks surrounding Tehran,Iran

Journal of Forestry Research 2014年第1期25卷 135-141页

The city of Tehran, like many polluted metropolises of the world, has higher emissions of greenhouse gases than other cities in Iran, due to heavy consumption of fossil fuel and landuse changes. To estimate carbon sequestration in two 40 year-old stands of plantedCupressus arizonica andFraxinus rotundifolia in degraded lands surrounding Tehran , sampling of above- and below- ground biomass, soil （at two depths of 0-15 and 15-30 cm）, and leaf litter was done by systematic random sampling. The total carbon stocks ofC. arizonica and F. rotundifolia stands were respectively 328.20 and 150.69 Mg·ha-1. The aboveground biomass with 233.16（71%） Mg·ha-1 inC. arizonica and 88.16 （58.50%） Mg·ha-1 inF. rotundifolia contributed the most shares to carbon sequestration. The diameter at breast height, total height, basal area, total volume, and biomass ofC. arizonica were significantly （p 〈0.01） higher than those ofF. rotundifolia. Also the depth of 0-30 cm of soil contributed between 18.29 % and 32.15 % of total ecosystem carbon, respectively. The economic value of carbon sequestration in the two stands in 2011 was calculated at 3.5 and 2.5 million dollars, respectively. Our results indicate that afforestation of the degraded land surrounding Tehran would sequester more carbon than would continuously degraded land, the current status quo. These stands can absorb atmospheric CO2at different rates, thus tree species selection and stand development should be considered in planning future afforestation projects.

作者： Fangqin Cheng Na Zhou Nazeer Muhammad Nouman Li Cui Caixia Yin Institute of resources and Environmental engineering State Environmental Protection Key Laboratory of Efficient Utilization of Coal Waste ResourcesShanxi University Key Laboratory of chemical Biology and Molecular engineering of Ministry of Education Institute of Molecular ScienceShanxi University

In recent years, the demand for strategic metal resources, essential for scientific and technological progress and industrial development, has multiplied. Ensuring a stable supply of these metals is critical to national security and the well-being of the population. As global industrialization accelerates, the daily demand for nonferrous metals continues to rise. Consequently,extracting and recovering strategic metals from low-grade raw materials, such as solid waste, has become crucial for maintaining their supply and economic development. However, the extraction process is fraught with challenges, including mineral phase stability and complex composition. This review focuses on key strategic metals such as lithium, aluminum, gallium, and vanadium. It introduces and examines various methods for extracting nonferrous metals from different raw materials, including traditional mining technologies applied to low-grade solid wastes. It also outlines future development opportunities and challenges in this field.
