Life-cycle assessment has been used to investigate the global warming potential (GWP) and fossil-energy requirement of a hypothetical operation in which biodiesel is produced from freshwater alga Chlorella vulgaris, grown using flue gas gas-fired power station as carbon source. Cultivation two-stage method was considered, whereby cells were initially high concentration biomass under nitrogen-sufficient conditions, before supply nitrogen discontinued, whereupon accumulated triacylglycerides....
The capacity of calcined limestone to react repeatedly with CO2, according CaO(cr) + CO2(g) = CaCO3(cr) (eq I), and also its regeneration in the reverse reaction have been studied a small, electrically heated fluidized bed sand, for five different limestones. forward step eq I is promising way removing CO2 from exhaust of, example, coal-fired power station, ready sequestration or as part scheme generate H2 using an enhanced water−gas shift reaction. regenerates sorbent. uptake by CaO,...
Microalgae have the potential to provide large amounts of lipid-containing biomass that could be used as a renewable oil feedstock for biofuel use. Many fast-growing algae, such Chlorella vulgaris, when grown under nutrient-sufficient conditions, lipid profile is unsuitable biodiesel use, since triacylglyceride content too low. However, growth nitrogen limitation has been shown increase triacylglycerides. Here we investigate most effective nitrogen-limitation regime and find rather than...
A chemical looping process, which uses a packed bed of the various oxides iron, has been formulated to produce separate, pure streams H2 and CO2 from syngas. The process following stages: (1) Reduction Fe2O3 Fe0.947O in syngas gasifying coal or biomass. This stage generates CO2, once water condensed. (2) Subsequent oxidation Fe3O4 using steam, simultaneously H2. (3) Further air return oxide step 1. Step 1 was studied here mixture CO + N2 as feed iron particles, while measuring concentrations...
Chemical looping combustion (CLC) is a novel technology that involves cyclic reduction and oxidation of oxygen storage materials to provide for the fuels CO2 H2O, whilst giving pure stream suitable sequestration or utilisation. Here, we report method preparing from layered double hydroxides (LDHs) precursors demonstrate their applications in CLC process. The LDHs precursor enables homogeneous mixing elements at molecular level, high degree dispersion high-loading active metal oxide support...
Abstract Cyanobacteria perform photosynthesis and respiration in the thylakoid membrane, suggesting that two processes are interlinked. However, role of respiratory electron transfer chain under natural environmental conditions has not been established. Through targeted gene disruption, mutants Synechocystis sp. PCC 6803 were generated lacked combinations three terminal oxidases: membrane-localized cytochrome c oxidase (COX) quinol (Cyd) cytoplasmic alternative oxidase. All strains...
Rationale: Electronic cigarette (e-cig) use has been widely adopted under the perception of safety. However, possibly adverse effects e-cig vapor in never-smokers are not well understood.Objectives: To test nicotine-containing vapors on airway mucociliary function differentiated human bronchial epithelial cells isolated from and airways a novel, ovine large animal model.Methods: Mucociliary parameters were measured sheep. Systemic nicotine delivery to sheep was quantified using plasma...
Abstract Coprecipitation and hydrolysis of CaO have been employed to produce Ca‐based synthetic sorbents suitable for capturing CO 2 in a fluidized bed. Their composition, uptake, volume small pores (2–200 nm) resistance attrition were measured compared those limestone dolomite. Sorbents produced by showed the highest uptake attrition. After 20 cycles carbonation calcination, two exceeded both dolomite, when subjected same regimes reaction. A sorbent's was shown be determined narrower than ∼200 nm.
