Co-liquefaction of Coal and Used Tire in Supercritical Water

open access: yesEnergy and Power Engineering, 2010
The co-liquefaction of lignite coal and used tire was performed in a 250-ml batch reactor, in supercritical water under a nitrogen atmosphere to investigate the effects of temperature (380-440℃), water/feedstock ratio (4/1-10/1 (wt./wt.)) and the % used tire content in the feedstock (0-100 wt.%) on the conversion efficiency, liquid yield and oil ...

Total Site Heat and Mass Integration and Optimisation using P-graph: A Biorefinery Case Study

open access: yesChemical Engineering Transactions, 2017
The aim of this paper is to solve total site heat and mass integration and optimisation using P-graph framework, with a biorefinery case study. Total site heat and mass integration is important for the selection of biorefinery processes because it must ...

Hydrothermal co-liquefaction of microalgae, wood, and sugar beet pulp [PDF]

open access: yesBiomass Conversion and Biorefinery, 2017
AbstractHydrothermal co-liquefaction of mixed (wet and dry) biomass residue streams would greatly enhance the viability and scale up potential of the technology as platform in bioenergy and biorefinery applications. This study aims to identify possible interaction effects between three different feeds (protein-rich microalgae, lignocellulosic wood, and

Supercritical water/CO liquefaction and a model for coal conversion

open access: yesFuel Processing Technology, 1986
Abstract Studies of Illinois No. 6 coal in CO/water at 400°C over a range of conversions to toluene-soluble (TS) products show product yields in D2O consistently superior to those in H2O, the yields leveling off respectively at 60% and 50%. These findings are compelling toward a conversion scheme in which coal is partitioned in parallel, competitive ...

Correlation of epididymal protease inhibitor and fibronectin in human semen. [PDF]

open access: yesPLoS ONE, 2013
OBJECTIVE:Epididymal protease inhibitor (Eppin) was located on the surface of spermatozoa and modulates the liquefaction of human semen. Here, we identify the correlative protein partner of Eppin to explore the molecular mechanism of liquefaction of ...

Synergetic hydrothermal co-liquefaction of crude glycerol and aspen wood [PDF]

open access: yesEnergy Conversion and Management, 2015
Crude glycerol-assisted hydrothermal co-liquefaction of aspen wood was studied in batch micro-reactors. An experimental matrix of 14 experiments was defined to investigate the effects of three different process parameters on the yields of biocrude and char, and on biocrude quality.
