Kinetic modeling of CO2 + CO hydrogenation to DME over a CuO-ZnO-ZrO2@SAPO-11 core-shell catalyst
(Elsevier, 2020-09-01)
A kinetic model for the CO2 + CO hydrogenation to dimethyl ether (DME) in a single step over an original core-shell structured CuO-ZnO-ZrO2@SAPO-11 bifunctional catalyst (metallic in the core and acid in shell) has been ...
Taking advantage of the excess of thermal naphthas to enhance the quality of FCC unit products
(Elsevier B.V., 2020-09-26)
Today, many European refineries finish up with excess of low-quality thermal naphthas that are hard to be marketed and, commonly, end being absorbed by catalytic naphthas at the expense of their higher quality. In this ...
Lessening coke formation and boosting gasoline yield by incorporating scrap tire pyrolysis oil in the cracking conditions of an FCC unit
(Elsevier, 2020-11-15)
We have studied the effect of adding scrap tire pyrolysis oil (STPO) as feed or co-feed in the cracking of vacuum gasoil (VGO) using a commercial equilibrated catalyst. The cracking experiments were performed in a laboratory ...
Towards waste refinery: Co-feeding HDPE pyrolysis waxes with VGO into the catalytic cracking unit
(Elsevier Ltd., 2020-01-28)
The co-feeding of high-density polyethylene pyrolysis waxes (HDPE waxes) with vacuum gasoil (VGO) on the catalytic cracking has been investigated. Runs have been conducted by feeding a blend of HDPE waxes/VGO (1/4 in mass) ...
Upgrading of heavy coker naphtha by means of catalytic cracking in refinery FCC unit
(Elsevier B.V., 2020-08)
The upgrading of heavy coker naphtha under conditions of the industrial fluid catalytic cracking (FCC) unit has been investigated, with the aim of obtaining light olefins and a gasoline fraction suitable to be used in the ...
Model validation of a packed bed LTA membrane reactor for the direct synthesis of DME from CO/CO2
(2020-10-16)
A model for simulating the direct synthesis of dimethyl ether (DME) in a packed bed membrane reactor (PBMR) has been validated, using a LTA zeolite hydrophilic membrane in a lab-scale reaction equipment. In the model, ...
