Propene oxide is a very important chemical whose production technology has changed lot during the last 30 years. Nowadays, most promising HPPO process in which propene produced by oxidizing with hydrogen peroxide, via titanium silicalite-1 (TS-1) catalysis. Even if this been patented early 1980s and some plants are already production, only few papers have published until now dealing catalytic kinetic aspects of process. In paper, state art scientific knowledge technical related to synthesis...
The epoxidized group, also known as the oxirane can be considered one of most crucial rings in chemistry. Due to high ring strain and polarization C–O bond this three-membered ring, several reactions carried out. One see such a functional group intermediate fuels, polymers, materials, fine chemistry, etc. Literature covering topic epoxidation, including catalytic aspect, is vast. No review articles have been written on synthesis short size, macro-molecules best our knowledge. To fill gap,...
In the present review article, definitions and most advanced findings within Process Intensification are collected discussed. The intention is to give readers basic concepts, fixing syllabus, as well some relevant application examples of a discipline that well-established considered hot topic in chemical reaction engineering field at present.
We present the quantitative conversion of guaiacol and diphenyl ether to cyclohexane over supported RuO 2 catalyst. In situ reduction species occurs simultaneously with hydrogenation process, contributing higher catalytic activity.
Reverse micelle nanoreactors were successfully designed to synthesize small-sized ceria nanocrystals (3.5–4.2 nm) with a sizeable amount of substitutional iron. Undoped and doped CeO2 catalysts an iron content (0.50–10 mol %) compliant the nominal value prepared tested for first time removal ibuprofen both in dark under UV or visible light irradiation. The effective inclusion distribution lattice ascertained through in-depth physicochemical characterization. In particular, X-ray diffraction...
Direct epoxidation of light olefin mixtures with hydrogen peroxide and titanium silicalite (TS-1) catalyst is interesting from a pure scientific viewpoint it might have considerable economic environmental advantages. implies significant process intensification as the separation steps alkenes prior to avoided. Binary ternary ethene, propene 1-butene were selectively epoxidized in presence TS-1 heterogeneous catalyst. Methanol was used solvent. Transient stationary kinetic experiments...
In the present paper, removal of fluoride from drinking was investigated via adsorption technique, an important contaminant that could cause serious threat to human health. The challenge this work is scale-up batch continuous operation, including regeneration adsorbent, using a commercial hydroxyapatite, namely Fuorandel®. Adsorption Dynamic Intraparticle Model (ADIM) used describe data collected in mode, obtaining parameters design column, such as: surface diffusivity, DS, and tortuosity,...
The need to reduce the environmental impact of steel industry necessitates development new production routes that drastically emissions carbon dioxide. A potential solution is change reductant from monoxide hydrogen. In such ironmaking technologies, it important understand iron oxide reduction kinetics under novel conditions. this work, a mathematical model small fixed-bed reactor was developed using key assumptions Shrinking Core Model describe reactive network and mass transport phenomena...
In the present work, a catalytic screening using most common heterogeneous acid catalysts was conducted, as raw material ethyl levulinate. Extensive catalyst revealed that Amberlyst-15 can be considered very suitable to promote DPE synthesis from levulinate and phenol. The use of allowed obtain 100% selectivity towards p,ṕ-DPE isomer, precursor for NIPU synthesis. A kinetic investigation conducted determine influence different parameters on reaction rate. Finally, mathematical model with...
Epoxidized soybean oil (ESBO) is produced in industry by reacting oil, at 60–70 °C, with hydrogen peroxide the presence of formic or acetic acid. A small amount sulphuric phosphoric acid necessary to catalyze oxidation carboxylic corresponding per-carboxylic Per-carboxylic acid, formed situ, migrates from aqueous phase where it spontaneously reacts double bonds give an oxirane ring. This reaction extremely exothermic (ΔH = −55 kcal/mol) and must be kept under thermal control. Two undesired...
Abstract The simple transfer of established chemical production processes from batch to flow chemistry does not automatically result in more sustainable ones. Detailed process understanding and the motivation scrutinize known conditions are necessary factors for success. Although focus is usually “only” on intensifying transport phenomena operate under intrinsic kinetics, there also a large intensification potential harsh specific design processes. Such an proposed required at early stage...
The kinetics of performic acid decomposition was studied with a gas-volumetric technique in which we measured the volume gas developed over time as consequence reaction. Several kinetic runs were performed presence catalytic amounts H2SO4 and H3PO4 autocatalytic conditions by mixing solutions HCOOH H2O2. trends curves (CO2) released, function time, all characterized more or less long induction followed straight line. Induction appeared to be related formation, rapidly reaching equilibrium,...
Propene oxide is a building block of the modern chemical industry. The research related to development convenient and greener processes has led HPPO (hydrogen peroxide propene oxide) process, where oxidized by hydrogen in presence methanol as solvent titanium silicalite (TS-1) catalyst. Even if first industrial plants based on this technology are already running, only few information have been published until now about kinetics particular regarding side reactions that lower yields increase...
