“…Ethylene is a good starter molecule to build on due to its simple chemical formula combined with the double bond. It is also the raw material for the production of different grades of polyethylene and other bulk and base chemicals , . Straight chain olefins can be produced by the oligomerization of ethylene through a process developed by Shell called the Shell higher olefin process (SHOP).…”

“…Straight chain olefins can be produced by the oligomerization of ethylene through a process developed by Shell called the Shell higher olefin process (SHOP). These higher chain hydrocarbons ( α ‐olefins) are used primarily as comonomers to produce linear low‐density polyethylene and to manufacture detergents and synthetic lubricants as well as gasoline, diesel, and jet blend stocks . For example, ethylene oxide, produced by oxidation of ethylene, is a key raw material in the production of surfactants and detergents.…”

Bioethylene Production from Ethanol: A Review and Techno‐economical Evaluation

2017

Manufacturing of bioethylene via dehydration of bioethanol is an alternative to the fossil-based ethylene production and decreases the environmental consequences for this chemical commodity. A few industrial plants that utilize 1st generation bioethanol for the bioethylene production already exist, although not functioning without subsidiaries. However, there is still no process producing ethylene from 2nd generation bioethanol. This study is divided into two parts. Different ethanol and ethylene production methods, the process specifications and current technologies are briefly discussed in the first part. In the second part, a techno-economic analysis of a bioethylene plant was performed using Aspen plus and Aspen Process Economic Analyzer, where different qualities of ethanol were considered. The results show that impurities in the ethanol feed have no significant effect on the quality of the produced polymer-grade bioethylene. The capacity of the ethylene storage tank significantly affects the capital costs of the process.

“…Gas hourly space velocity (GHSV, h −1 ) is an important process condition to consider. Typical ethane steam cracking units operate at a GHSV range of 1800–8000 h −1 STP . Figure illustrates the effect of changing space velocity with the relatively less active Na 2 WO 4 /Mg 6 MnO 8 redox catalyst (Figure a) and the more active Na 2 WO 4 /CaMnO 3 redox catalyst (Figure b).…”

“…These processes are used to produce light olefins such as ethylene and propylene, two essential chemical building blocks with a combined global production of 220 million metric tons in 2012 . The production of polyethylene, ethylene oxide, polypropylene, acrylonitrile, and many other critical industrial intermediates relies on these light olefins as feed chemicals . At present, ethylene and propylene are primarily produced via these energy‐intensive processes, consuming approximately 8% of total primary energy use in the chemicals sector .…”

Manganese‐containing redox catalysts for selective hydrogen combustion under a cyclic redox scheme

et al. 2018

Selective hydrogen combustion (SHC) in the presence of light hydrocarbons was demonstrated with a series of Mn‐containing mixed oxide redox catalysts in the context of a chemical looping‐oxidative dehydrogenation scheme. Unpromoted and 20 wt % Na2WO4‐promoted Mg6MnO8, SrMnO3, and CaMnO3 exhibited varying SHC capabilities at temperatures between 550 and 850°C. Reduction temperature of unpromoted redox catalysts increased in the order Mg6MnO8 < SrMnO3 < CaMnO3. Promotion with 20 wt % Na2WO4 resulted in more selective redox catalysts capable of high‐temperature SHC. XPS analysis revealed a correlation between suppression of near‐surface Mn and SHC selectivity. Na2WO4/CaMnO3 showed steady SHC performance (89% H2 conversion, 88% selectivity) at 850°C over 50 redox cycles. In series with a Cr2O3/Al2O3 ethane dehydrogenation catalyst, Na2WO4/CaMnO3 combusted 84% of H2 produced while limiting COx yield below 2%. The redox catalysts reported can be suitable for SHC in a cyclic redox scheme for the production of light olefins from alkanes. © 2018 American Institute of Chemical Engineers AIChE J, 64: 3141–3150, 2018

“…Eine Vielzahl von Arbeiten beschäftigt sich mit der oxidativen Kopplung von Methan. Allerdings schienen bislang die niedrigen Ausbeuten (20 – 25 %) 13 nicht dazu angetan, eine industrielle Umsetzung in Erwägung zu ziehen. Kürzlich kündigten die Firmen Linde und Siluria jedoch an, bis Ende 2014 eine Demoanlage in Betrieb zu nehmen 14.…”

Die derzeitige Entwicklung in den USA, geprägt durch billiges Schiefergas, hat starke Auswirkungen auf die Produktion von Basischemikalien. Der Beitrag geht der Frage nach, ob sich vor diesem Hintergrund der Anteil nachwachsender Rohstoffe für die Chemikalienproduktion steigern lässt oder ob sich die Zahl biobasierter Produkte und Verfahren eher verringern wird. Antworten liefert für einige ausgewählte Grundchemikalien der Vergleich von bestehenden Produktionsverfahren auf petrochemischer Basis mit Alternativen auf Basis nachwachsender oder anderer fossiler Rohstoffe (bspw. Methan und niedere Alkane).
