Gasification of pelletized renewable fuel for clean energy production

2011

Abstract The main aim of the study was to develop and investigate a small-scale experimental gasification technique for the effective thermal decomposition of pelletized renewable fuels (wood sawdust, wheat straw). The technical solution of the biomass gasifier for gasification of renewable fuels presents a downdraft gasifier with controllable additional heat energy supply to the biomass using the radial propane flame injection into the bottom part of the biomass layer. From the kinetic study of the mass conversion rate of pelletized biomass and variations of the composition of produced gas it is concluded that the process of biomass gasification is strongly influenced by the amount of addi…

Self-assembly of Clicked Star-Shaped Triazines into Functional Nanostructures

2019

Two non‐amphiphilic star‐shaped 2,4,6‐tris(1,2,3‐triazol‐4‐yl)‐1,3,5‐triazines showing different behavior in terms of self‐assembly and luminescent properties are described. They aggregate in the liquid phase to form low‐dimensional nanostructures with a variety of morphologies, such as spherical particles, one‐hole hollow spheres, toroids, twisted fibers or helical nanotubes, just by varying the conditions of a straightforward reprecipitation method. Aggregation has an opposite effect concerning the fluorescent properties of the proposed compounds, either causing the enhancement or the quenching of the emission after the self‐assembly. Quantum chemical calculations have been also performed…

Recent developments and applications of smart nanoparticles in biomedicine

2022

Abstract Over the last decades, nanotechnology applied in medicine (nanomedicine) has sparked great interest from the scientific community, thanks to the possibility to engineer nanostructured materials, including nanoparticles (NPs), for a specific application. Their small size confers them unique properties because they are subject to physical laws in the middle between classical and quantum physics. This review is proposed to explain better how to design a specific NP and clarify the relationship between the type, size, and shape of NPs and the specific medical applications. NPs are classified into inorganic (metallic NPs, quantum dots, carbon-based nanostructures, mesoporous silica NPs)…

Towards controlling PCDD/F production in a multi-fuel fired BFB boiler using two sulfur addition strategies. Part II: Thermodynamic analysis

2014

Abstract A staged equilibrium process model was developed for a bubbling fluidized bed boiler firing SRF, bark and sludge. The model was used to study the influence of sulfur addition strategies (S-pellet additive and peat co-firing) on the behavior of copper, bromine, and alkalis. Aerosol samples collected from the backpass of the boiler were used to validate the chemistry predicted by the model. The model revealed that Cu existed as Cu 2 S (s3) in the reducing zone, and CuCl (g) (for all test cases) and CuO (s) (during peat co-firing) in the oxidation zones. CuBr 3(g) was also present after the introduction of tertiary air. However the model failed to predict the formation of CuSO 4 , an …

Demographic Analysis of Bucharest-Ilfov Region

2013

Abstract This paper aims to achieve a study was to research, analyze and interpret statistical data, in conjunction with theoretical aspects that allowed assessment of regional information on population structure in the Bucharest-Ilfov. Bucharest-Ilfov region's population (2,264,865 inhabitants in 2012) is distributed inversely proportional to the size of two administrative entities (Bucharest - the capital of Romania - Ilfov county). Bucharest is the largest urban agglomeration in Romania, its population being 1,924,299 inhabitants, representing about 85% population of the region, more than 16.4% of the urban population of the country, or around 9% of the total population of Romania and ha…
