To understand the effect of torrefaction severity on structure changes hemicellulose, cellulose, lignin and their subsequent catalytic fast pyrolysis (CFP) behavior, lignin, cellulose was performed in a tubular reactor with different reaction temperatures (210–300 °C) residence times (20–60 min). The experimental results show that rank order thermal stability during > hemicellulose. torrefied hemicelulose, were subsequently catalytic-fast-pyrolyzed over HZSM-5 semi-batch pyroprobe reactor....
Chemical-looping reforming (CLR) is a technology that can be used for partial oxidation and steam of hydrocarbon fuels. It involves the use metal oxide as an oxygen carrier, which transfers from combustion air to fuel. Composite carriers cerium added with Fe, Cu, Mn oxides were prepared by co-precipitation investigated in thermogravimetric analyzer fixed-bed reactor using methane fuel oxidizing gas. was revealed addition transition-metal into improve reactivity Ce-based carrier. The three...
Chemical looping gasification (CLG) is considered as a novel technology because gas-phase oxygen of the gasifying medium can be replaced by lattice carrier. The mediums (e.g., pure O2 and steam) used source apparently improve char conversion in traditionally biomass gasification. Similarly, objective this study to investigate CLG with carrier an individual source. A NiO-modified iron ore was prepared impregnation method coupled ultrasonic treatment. characteristics were analyzed X-ray...
Torrefaction experiments of sprucewood and bagasse were performed in an auger reactor at 260 °C, 280 300 °C. The chemical composition pyrolysis behavior the resulting torrefied biomass examined detail. A number water lightweight organic compounds removed from through torrefaction treatment. Chemical component analysis showed that more acid insoluble fibers formed bagasses obtained which suggested cross-linking carbonization carbohydrates probably took place torrefaction. FTIR (Fourier...
The objective of this paper is to systematically investigate the influences different preparation methods on properties NiFe2O4 nanoparticles as oxygen carrier in chemical looping hydrogen production (CLH). solid state (SS), coprecipitation (CP), hydrothermal (HT), and sol–gel (SG) were used prepare carriers. Samples characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), photoelectron spectroscopy (XPS), Brunauer–Emmett–Teller (BET) surface area...
Chemical looping oxidative dehydrogenation (CL-ODH) represents a redox approach to convert ethane into ethylene under an autothermal scheme. Instead of using gaseous oxygen, CL-ODH utilizes lattice oxygen in transition metal oxides, which acts as carrier or catalyst, facilitate the ODH reaction. The oxygen-deprived catalyst is subsequently regenerated with air and releases heat. current study investigated alkali (Li, Na, and/or K)-promoted LaxSr2–xFeO4−δ (LaSrFe) catalysts for ethane. While...
Chemical looping steam reforming (CLSR) is a novel technology for hydrogen production using metal oxide as an oxygen carrier (OC). During the CLSR, OC (MeO) first reduced to final state (Me) by fuel, and then decomposes water vapor produce hydrogen, while it recovers part of lattice intermediate (MeO1−δ); finally, remaining into initial under air atmosphere. This work explore reactivity NiFe2O4 during CLSR based on thermodynamic predictions experimental analysis. The analysis shows that...
We firstly propose the coupling conversion of bio-derived furans and methanol over ZSM-5 for enhancing aromatic production. The was conducted in a continuous fixed bed reactor. 2-Methylfuran (MF) used as probe molecule to identify possible reaction pathways. effects MF molar ratio, temperature weight hourly space velocity (WHSV) on product distribution from were investigated. experimental results showed that yield is about 5.2 times higher than catalytic fast pyrolysis only MF. In addition,...
