Biomass fast pyrolysis oil is a potential renewable alternative to fossil fuels, but its viability constrained by corrosiveness, low higher heating value and instability, caused high oxygenate concentrations. A few studies have outlined layered double hydroxides (LDHs) as possible catalysts for the improvement of biomass characteristics. In this study, goal was reduce concentration oxygen-rich ...

This paper examines the question: what does corrosive capital mean, and enables it in Serbia? Through design of an analytical framework robust literature review, this adds value to understudied topic International Political Economy by giving rigidity a term that is generally used as ostensive buzzword. deter-mines projects are extent they benefit elites at public's expense. Corrosive elements c...

Iron (Fe(0) ) corrosion in anoxic environments (e.g. inside pipelines), a process entailing considerable economic costs, is largely influenced by microorganisms, in particular sulfate-reducing bacteria (SRB). The process is characterized by formation of black crusts and metal pitting. The mechanism is usually explained by the corrosiveness of formed H(2) S, and scavenge of 'cathodic' H(2) from...

Coiled tubing corrosion was investigated for 16 field water samples (S5 to S20) from a Canadian shale gas field. Weight loss corrosion rates of carbon steel beads incubated with these field water samples averaged 0.2 mm/yr, but injection water sample S19 had 1.25±0.07 mm/yr. S19 had a most probable number of zero acid-producing bacteria and incubation of S19 with carbon steel beads or coupons d...

Efficient control of pathogenic bacteria, specifically Legionella pneumophila, is one the main concerns when operating industrial cooling towers. Common practices to limit proliferation involves use disinfectants, leading formation disinfection by-product and increase in water corrosiveness. A disinfectant-free method would make industry more environmentally friendly. pilot-scale tower (1 m3/h)...

The aims of this study were to assess and analysis of drinking water quality of Chabahar villages in Sistan and Baluchistan province by water quality index (WQI) and to investigate the water stability in subjected area. The results illustrated that the average values of LSI, RSI, PSI, LS, and AI was 0.5 (±0.34), 6.76 (±0.6), 6.50 (±0.99), 2.71 (±1.59), and 12.63 (±0.34), respectively. The calcu...

A fundamental study of scale formation of calcium carbonate (CaCO3) for producing oil wells has been carried out. This article presents the study of the prediction of salt deposition in two different synthetic formation waters and investigates the effects of temperature and pressure on calcium carbonate precipitation. The dependence of the induction period of the precipitation of calcium carbon...

Abstract Many wooden Chinese historic buildings are destroyed due to the ravages of frequent fire disasters. The risk highly enlarged since a long-time weathered structures in natural environment. clean fire-extinguishing technology using fluorinated chemical gases put out building rapidly at initial stage is recommended and widely used. However, gaseous hydrogen fluoride (HF) yielded during su...
