A kinetic model has been proposed for the synthesis of dimethyl ether in a single reaction step from (H2 + CO) and CO2), parameters have calculated CuO−ZnO−Al2O3/γ-Al2O3 bifunctional catalyst. The suitably fits experimental results obtained an isothermal fixed bed reactor within wide range operating conditions: 225−325 °C; 10−40 bar; space time, 1.6−57.0 (g catalyst) h (mol H2)-1. crucial steps modeling are methanol CO)synthesis CO2) is not importantmethanol dehydration (very fast),...
The catalytic cracking of a blend raw bio-oil (20 wt %) from black poplar sawdust fast pyrolysis and vacuum gasoil (VGO, 80 has been studied. runs have performed in riser simulator reactor (RSR) under fluid (FCC) conditions; that is, 500–560 °C, catalyst to feed mass ratio 6 gcat (gfeed)–1 on dry basis, reaction times 3–10 s equilibrated commercial FCC catalyst. cofeeding effect quantified by comparing the yields product lumps individual components gaseous fraction gasoline lump VGO,...
The kinetics of the catalytic cracking plastic pyrolysis oil (PPO) over three FCC (fluid cracking) equilibrium commercial catalysts has been modeled. PPO comes from fast high-density polyethylene (HDPE). runs have carried out in a laboratory-scale reactor under conditions: 500–560 °C; catalyst/oil weight ratio 5 gcat gPPO-1; and contact time 1.5–6 s. Four different reaction schemes composed six lumps compared it obtained by statistical means that simplest one is most appropriate for...
The aim of this paper is for the production oils processed in refineries to come from pyrolysis real waste high plastic content rejected by recycling industry Basque Country (Spain). Concretely, streams were collected (1) a light packaging sorting plant, (2) industry, and (3) treatment plant electrical electronic equipment (WEEE). influence pre-treatments (mechanical separation operations) temperature on yield quality liquid fraction evaluated. In order study pre-treatment effect, samples...
The thermal and catalytic cracking of several plastic wastes (polypropylene, polystyrene, polystyrene−polybutadiene) dissolved in refinery LCO has been studied a riser simulator, under operating conditions (catalyst, temperature, contact time, C/O ratio) that are similar to commercial FCC units. results the product distribution show interest this strategy, which may be integrated into operation for large-scale tertiary exploitation wastes.
The nature and composition of the coke deposited on Pt–Pd catalysts supported acid carriers during hydroprocessing (hydrocracking hydrotreating) light-cycle oil (LCO) has been studied. Five types supports have used: a commercial cracking catalyst, alumina, Hβ zeolite, two HY zeolites (with different acidities). hydrocracking runs performed at 350 °C 50 bar for up to 24 h. characterization deactivating species catalyst used using temperature-programmed oxidation (TPO) coupled with mass...
