Carbon dioxide is a primary greenhouse gas that plays vital role in shaping life on Earth. However, the continuous anthropogenic emissions of CO2 at prominent levels have caused severe damage to earth as they increase global average temperature earth, causing warming. To restrict further rise temperature, it necessary capture efficiently by various means. Technological carbon sequestration would benefit manufacturing industry minimizing and saving taxes. This review article explore methods improving storage technology, using captured economically industries, making fuel from carbon. Cooling towers can be used through direct air (DAC) method integrated with Natural Draft Dry Tower systems (NDDCTs) lower power consumption requirements thus operational costs. The make employing solid directly both an anode fuel, 80% higher efficiency than oxide cells. It also emits fewer pollutants typical coal-burning plants.

Abstract. Furans are emitted to the atmosphere during biomass burning from pyrolysis of cellulose. They one major contributing volatile organic compound (VOC) classes OH and NO3 reactivity in plumes. The removal process furans at night is reaction with nitrate radical, NO3. Here, we report a series relative rate experiments 7300 L indoor simulation chamber Institut de Combustion Aérothermique Réactivité et Environnement, Centre national la recherche scientifique (ICARE-CNRS), Orléans, using number different reference compounds determine coefficients for four furans, two furanones, pyrrole.

Domestic, or household-level, open burning of plastic waste is a source air pollutants and greenhouse gases that are often neglected in emission inventories. Domestic considerable concern Guatemala due to the lack access collection services, particularly rural areas. This paper offers first attempt estimate emissions from domestic at city departmental levels Guatemala. Data were collected Xalapán region Jalapa, analyzed determine change generation over time as well socioeconomic factors may affect extent burning. The annual per capita masses burned used Xalapán, cities Jutiapa city, all 22 departments Our results show areas burn more domestically, likely because collection, 30.4% OC, 24.0% BC, 23.6% PM

Comprehensive characterization of particulate intermediate-volatility and semi-volatile organic compounds (I/SVOCs) from heavy-duty diesel vehicles using two-dimensional gas chromatography time-of-flight mass spectrometry

Abstract. Tailpipe emissions from three heavy-duty diesel vehicles (HDDVs), complying with varying emission standards and installed diverse aftertreatment technologies, are collected at a certified chassis dynamometer laboratory. The HDDV-emitted intermediate-volatility semi-volatile organic compound (I/SVOC) the gas–particle partitioning of I/SVOCs investigated. Over 4000 compounds identified grouped into 21 categories. dominant groups particulate alkanes phenolic compounds. For HDDVs without devices, i.e., oxidation catalysts (DOCs) filters (DPFs), emitted partition dramatically gas phase (accounting for ∼ 93 % total I/SVOC mass), few exceptions: hopane, four-ring polycyclic aromatic hydrocarbons (PAH4rings), five-ring (PAH5rings). DPFs DOCs, fractions reduced to negligible level (i.e., less than 2 %). Nevertheless, 50 two-ring PAH mass is detected in particle phase, which much higher high-molecular-weight PAHs, arising positive sampling artifact quartz filter absorbing vapors. vapors clearly observed, uncertainties discussed quantified.

Abstract. Solid fuel (SF) combustions, including coal and biomass, are important sources of pollutants in the particle gas phase therefore have significant implications for air quality, climate, human health. In this study, we systematically examined gas-phase emissions, using Vocus proton-transfer-reaction time-of-flight (PTR-TOF) mass spectrometer, from a variety solid fuels, beech logs, spruce/pine branches needles, straw, cow dung, coal. The average emission factors (EFs) organic vapors ranged 4.8 to 74.2 g kg−1, depending on combustion phases types. Despite slight differences modified efficiency (MCE) some experiments, increasing EFs were observed with lower MCE. relative contribution different classes showed large similarities between logs stove burning, change observed. CxHyOz family is most abundant group vapor emitted all SF combustion. However, among these greater nitrogen-containing species CxHy families (related polycyclic aromatic hydrocarbons) dung burning respectively. Intermediate-volatility compounds (IVOCs) constituted fraction emissions combustion, ranging 12.6 % 39.3 %. This was particularly notable needles (39.3 %) (31.1 %). Using Mann–Whitney U test studied identified specific potential new markers fuels based measurements. product pyrolysis coniferyl-type lignin extract cedar pine needle as open (e.g., C10H14O2, C11H14O2, C10H10O2).
