Waste tyre valorization by catalytic pyrolysis – A review
(Elsevier, 2020-06-05)
[EN] The environmental concern associated with waste tyre disposal and the necessity of sustainable waste management policies has promoted the development of waste tyre valorization processes in the last decades. Within ...
Influence of reactor and condensation system design on tyre pyrolysis products yields
(Elsevier B.V., 2019-09-07)
This study investigates the effect the pyrolysis reactor and the condensing system type have on the tyre derived oil (TDO) and DL-limonene yield, as well as benzothiazole concentration in the TDO. All the experiments were ...
Experimental study and modeling of biomass char gasification kinetics in a novel thermogravimetric flow reactor
(Elsevier B.V., 2020-04-25)
[EN]This work pursues the validation of a new reactor for the evaluation of char gasification kinetics. This novel reactor allows continuous gas flow through the fixed bed sample and accurately monitoring the mass loss ...
Pyrolysis of plastic wastes in a fountain confined conical spouted bed reactor: determination of stable operating conditions
(Elsevier, 2020-12-31)
[EN] The performance of both fluidized and spouted bed reactors in the pyrolysis of waste plastics is conditioned by particle agglomeration phenomena, which worsen the quality of the gas-solid contact and eventually lead ...
Cost-effective upgrading of biomass pyrolysis oil using activated dolomite as a basic catalyst
(Elsevier B.V., 2019-07-19)
This study deals with a continuous process on a calcined dolomite operating at atmospheric pressure and by cofeeding
water for cost-effective upgrading of raw bio-oil at 400 °C and 500 °C. The distribution of carbon in ...
A sequential process for hydrogen production based on continuous HDPE fast pyrolysis and in-line steam reforming
(Elsevier, 2016-07-15)
A continuous process has been developed consisting in the flash pyrolysis (500 ºC) of high density polyethylene (HDPE) in a conical spouted bed reactor (CSBR) followed by steam reforming in a fluidized bed reactor (Ni ...
Catalysts of Ni/α-Al2O3 and Ni/La2O3-αAl2O3 for hydrogen production by steam reforming of bio-oil aqueous fraction
(Elsevier, 2012-12-04)
This paper reports on the steam reforming, in continuous regime, of the aqueous fraction of bio-oil obtained by flash pyrolysis of lignocellulosic biomass (sawdust). The reaction system is provided with two steps in series: ...
A comparative thermodynamic study on the CO2 conversion in the synthesis of methanol and of DME
(Elsevier, 2017-02-01)
A thermodynamic approach of the synthesis processes of methanol and DME from H2+CO+CO2 has been conducted, in order to compare the feasibility of incorporating CO2 in the feed of both processes. The effects of reaction ...
Coking and sintering progress of a Ni supported catalyst in the steam reforming of biomass pyrolysis volatiles
(Elsevier, 2018-10)
The valorization of biomass (pine wood) for hydrogen production has been studied in a
two-step process, comprising pyrolysis and subsequent steam reforming of the volatiles
produced in the first step. This work focuses ...
Comparison of Ni based and Rh based catalysts performance in the oxidative steam reforming of raw bio-oil
(ACS, 2017-06-17)
The effect of O2 content in the oxidative steam reforming (OSR) of raw bio-oil has been studied, and the kinetic behavior, particularly deactivation, has been compared between two catalyst (Ni/La2O3-αAl2O3 and Rh/CeO2-ZrO2). ...
