Bio-hydrogen production by APR of C 2 -C 6 polyols on Pt/Al 2 O 3 : Dependence of H 2 productivity on metal content
(Elsevier Science, 2017-11)
The effect of the platinum loading on the production of hydrogen by aqueous-phase reforming of ethylene glycol, glycerol, xylitol and sorbitol was studied on Pt/Al2O3 catalysts containing 0.30, 0.57, 1.50 and 2.77 Pt%. ...
The effect of different palm oil-based bio-polyols on foaming process and selected properties of porous polyurethanes
(John Wiley & Sons Ltd, 2017-06-02)
Rigid polyurethane foams were successfully prepared by blending up to 70wt% of two different palm oil-based bio-polyolswith a petrochemical polyether polyol. The bio-polyols were synthesized by epoxidation?oxirane ring-opening ...
Linseed oil-based polyurethane rigid foams: synthesis and characterization
(Scrivener Publishing, 2015-03-01)
Rigid polyurethane foams were synthesized by using a vegetable oil-based polyol and 4,4-diphenylmethane diisocyanate prepolymer as the majority of reactives,. The polyol was produced by hydroxylation of crude linseed oil ...
Flexible polyurethane foams modified with bio-based polyols: synthesis and physical/chemical characterization
(John Wiley & Sons Inc, 2016-05-30)
A series of flexible polyurethane foams with different polyol compositions were synthesized through the replacement of aportion of the petroleum-based polyether polyol with biobased polyols, namely, glycerol (GLY) and ...
Solid"green" polyurethanes based on rapeseed oil polyol and modified withglycerol and microcellulose
(Scrivener Publishing, 2016-08-01)
Solid bio-based polyurethanes (PUs) were prepared from a rapeseed oil-based polyol (ROPO) synthesized by epoxidation reaction followed by oxirane ring-opening with diethylene glycol. The reference material was modified by ...
Cellulose nanocrystal reinforced acylglycerol-based polyurethane foams
(Budapest University of Technology and Economics, 2020-05)
This work presents the preparation of polyurethane composite foams based on castor oil or modified canola oil as a polyol, and cellulose nanocrystals (CN) as nanofiller (0.10, 0.25, and 0.50 wt% of CN content). The bio-based ...
