A shrinking core model and empirical kinetic approaches in supercritical CO2 extraction of safflower seed oil
(Elsevier, 2014)
Utilization of supercritical CO2 in safflower seed extraction was performed using a semi-batch extractor. Different extraction parameters, such as 40-60 MPa pressure, 323-347 K temperature, 20-76 min time, and 1-3 mL/min ...
Co-pyrolytic behaviors of biomass and polystyrene: Kinetics, thermodynamics and evolved gas analysis
(Korean Institute Chemical Engineers, 2018)
The pyrolytic degradation mechanism of chestnut shell (CNS) and its blend with waste polystyrene (PS) were investigated. Individual pyrolysis behavior of samples obtained separately was compared with those of the blends ...

A Comparative Characterization of the HPA-MCM-48 Type Catalysts Produced by the Direct Hydrothermal and Room Temperature Synthesis Methods
(Hindawi LTD, 2012)
MCM-48 type support materials synthesized by the direct hydrothermal synthesis (HTS) and room temperature synthesis (RTS) methods were incorporated with tungstophosphoric acid (TPA) in the range of 10-40 wt% by using a wet ...
Bio-oil production via co-pyrolysis of almond shell as biomass and high density polyethylene
(Pergamon-Elsevier Science LTD, 2014)
Biomass from almond shell (aS) was co-pyrolyzed with high density polyethylene (HDPE) polymer to investigate the synergistic effects on the product yields and compositions. The pyrolysis temperature was selected as 500 C, ...
Rapid and catalytic pyrolysis of corn stalks
(Elsevier Science BV, 2009)
Non-catalytic and catalytic rapid pyrolysis of corn stalks was studied in a tubular fixed-bed reactor. The optimum operating conditions giving the highest liquid yield was determined as pyrolysis temperature of 500 degrees ...
Comparative analysis of pyrolysis oils and its subfractions under different atmospheric conditions
(Elsevier Science BV, 2006)
In this paper comparative analysis of bio-oils and their subtraction from static, sweeping gas and steam pyrolysis of apricot pulp, a food industry waste, was investigated. Experimental studies were conducted in a well-swept ...
Kinetics of esterification of acetic acid with 1-octanol in the presence of Amberlyst 36
(Elsevier Science BV, 2012)
Kinetic data on the esterification of acetic acid with 1-octanol were obtained from both uncatalyzed and heterogeneously catalyzed reactions using a stirred batch reactor in toluene. The equilibrium constant, K-C, which ...
