The article presents the results of research on impact feeding marine reciprocating internal combustion engines with blends diesel fuel and n-butanol their performance parameters. study includes a plan empirical results, in which engine efficiency emissions harmful compounds exhaust gases were determined. indicates that it is resonable to use containing n-butanol. N-butanol positively affect co...

In recent decades, many kinds of research have been conducted on alternative fuels for compression ignition (CI) engines. Low/zero-carbon fuels, such as bioalcohols and hydrogen, are the most promising extensively studied because their availability, ease manufacturing, environmental benefits. Using these in CI engines is environmentally economically beneficial. The common alcohols methanol, eth...

This work reports an experimental and numerical analysis on the sooting characteristics of butanol isomers. Light extinction gas chromatography were used to measure soot gas-phase species, respectively. Kinetic tested flames was performed with detailed mechanism a sectional model. The present aims provide understanding effects isomeric structures tendencies. For comprehensive analysis, both nea...

The main objective of this study was assessment the performance, emissions and combustion characteristics a diesel engine using RME–1-butanol blends. In assessing process, great importance placed on evaluating stability process. Not only were typical COVIMEP indicators assessed, but also non-burnability characteristic stages: ignition delay, time 50% heat release end combustion. evaluation proc...

the whole plant, pergularia daemia (family: asclepediaceae), was extracted with 50% alcohol and a fresh batch of the plant material was successively extracted with petroleum ether, ethyl acetate and n-butanol to determine its diuretic activity. the diuretic activity of the different extracts at a dose of 400 mg/kg was assessed orally in rats with furosemide as a standard drug using lipschitzs t...

UNLABELLED BACKGROUND Previously we have developed a butanol tolerant mutant of Clostridium acetobutylicum Rh8, from the wild type strain DSM 1731. Strain Rh8 can tolerate up to 19 g/L butanol, with solvent titer improved accordingly, thus exhibiting industrial application potential. To test if strain Rh8 can be used for production of high level mixed alcohols, a single secondary alcohol deh...

2-Butanol has been an issue of industries in many areas, for example, biofuel production (as an advanced alternate fuel), fermented beverages, and food (as taste-altering component). Thus, its source of production, the biological pathway, and the enzymes involved are of high interest. In this study, 42 different isolates of lactic acid bacteria from nine different species were screened for thei...

BACKGROUND Traditional approaches to phenotype improvement include rational selection of genes for modification, and probability-driven processes such as laboratory evolution or random mutagenesis. A promising middle-ground approach is semi-rational engineering, where genetic modification targets are inferred from system-wide comparison of strains. Here, we have applied a metabolomics-based, se...

A counter-current CO₂ fractionation method was applied as a mean to recover n-butanol and other compounds that are typically obtained from biobutanol fermentation broth from aqueous solutions. The influence of operating variables, such as solvent-to-feed ratio, temperature, pressure and feed solution composition was experimentally studied in terms of separation efficiency, butanol removal rate,...

Saccharomyces cerevisiae has increasingly been engineered as a cell factory for efficient and economic production of fuels and chemicals from renewable resources. Notably, a wide variety of industrially important products are derived from the same precursor metabolite, acetyl-CoA. However, the limited supply of acetyl-CoA in the cytosol, where biosynthesis generally happens, often leads to low ...
