Coupling of an acoustic emissions system to a laboratory torrefaction reactor 10.1016/j.jaap.2017.12.008 2017-12-23 This article describes the use and characterization of an acoustic system coupled to a torrefaction reactor. The reactor, including phase shift and frequency, was characterized by applying both Lissajous/Hilbert and cross-spectrum techniques. Optimum acoustic...
Valorization of coffee silverskin industrial waste by pyrolysis: from optimization of bio-oil production to chemical characterization by GC × GC/qMS 10.1016/j.jaap.2017.12.005 2017-12-13 Coffee bean tegument (silverskin) is a by-product derived from the coffee roasting process. This residue has been discarded, which constitutes a serious environmental problem. The depletion of oil reserves and environmental issues promoted by the combustion o...
Cement catalyzed conversion of biomass into upgraded bio-oil through Microwave metal interaction Pyrolysis in aluminum coil reactor 10.1016/j.jaap.2017.12.006 2017-12-12 Metal objects spark in the microwaves, exposing metals to melting point temperatures. The resulting heat can be utilized for the pyrolysis of biomass into upgraded bio oil. In this work pyrolysis was carried out both in the presence and absence of catalyst an...
Catalytic fast pyrolysis of cellulose to produce furan compounds with SAPO type catalysts 10.1016/j.jaap.2017.12.004 2017-12-10 Furans, such as furfural (FF) and 5-hydroxymethyl-furfural (HMF), are recognised as target high-value chemicals produced through catalytic fast pyrolysis (CFP) of biomass. In this work, a series of SAPO type catalysts were introduced in the CFP of cellulose t...
Pyrolytic behaviors of decocting residues of Rhodiola rosea 10.1016/j.jaap.2017.12.003 2017-12-06 Pyrolysis behaviors of decocting residues of Rhodiola rosea (RR) were studied by TGA and Py-GC/MS. Results indicated that with an increase of decocting time from 0 to 4 h, the contents of extractives and hemicellulose decreased from 29.15 and 5.35 wt.% to 28....
