A nozzle inclination angle and swirl combustor inside the low-tar biomass (LTB) gasifier reactor were tested optimized to evaluate these effects on tar reduction design tar-free producer gas. The process is mainly based concept of a swirling flow created by angle, with 55° radial line, allowing good mixing between pyrolysis gases gasifying agents. separate has large internal annular reverses zo...

Surface plasmon resonance (BIACORE) was used to determine the kinetic values for formation of the HIV TAR-TAR* ('kissing hairpin') RNA complex. The TAR component was also synthesized with the modified nucleoside 2-thiouridine at position 7 in the loop and the kinetics and equilibrium dissociation constants compared with the unmodified TAR hairpin. The BIACORE data show an equilibrium dissociati...

The pyrolysis of briquettes made from biomass is an available and economic technological route for the production of briquette charcoal, but by-products (tar and gas) cannot be brought into full utilization, leading to the waste of resources and the addition of environmental concerns. Temperature is the most important parameter that affects the distributions and properties of briquette charcoal...

Pyrolysis is a process by which a biomass feedstock is thermally degraded in the absence of air/oxygen. It is used for the production of solid (charcoal), liquid (tar and other organics) and gaseous products. In the present study, a mathematical model to describe the pyrolysis of a single solid particle of biomass is used to study the effect of convective heat transfer coefficient and orders of...

The main purpose of this study is to investigate the thermal stability and mechanism decomposition Mogoin gol coal, possibility liquefaction by pyrolysis thermolysis, enriching heavy liquids reduce mineral content coal improve its quality. Under purpose, was characterized proximate ultimate analysis, thermogravimetry, investigated (thermolysis pyrolysis). Thermogravimetric analysis performed us...

NREL's thermochemical biomass conversion research is focused on ex-situ upgrading of fast-pyrolysis (FP) vapors as an efficient route to completely biogenic pyrolysis-based fuel precursors, fuels, and value-added chemicals depending catalyst process conditions. A near term pathway being developed uses these liquids for co-processing with petroleum feedstocks assess carbon incorporation in hydro...

Disposal of chrome tanned leather waste (CTLW) generated in leather processing industries has many environmental implications. This paper presents a double pyrolysis (PI & PII) method to dispose hazardous chrome tanned leather solid waste by converting it into useful products. When CTLW was subjected to double pyrolysis, three major products obtained were; (i) an energy enriched combustible gas...
