“…It is clear that the potential emission reduction by stepwise improvements to the conventional process is limited unless CCS is used. 22 For example, by combining high emissivity coatings with novel aluminum-based alloys, reactive coatings in the coil, 23 3D machined reactors, and novel process design, at best can result in 30% emission reductions as shown by Brown et al 24 So, more drastic innovations are needed. Electrification might offer the opportunity to drastically change the process to enhance energy efficiency and product yield.…”

Due to our increasing awareness of the impact of climate change on our society, unit operations in our manufacturing processes, including those in chemical industry, have to be greenified and made less dependent of fossil resources. This so-called electrification of the chemical industry is still yet in its infancy but there are many scientific and technological challenges to be solved. This article provides some directions for further research for scientists in both academia and industry to move step by step to an e-chemistree. These important but far from trivial energy and materials transitions require not only the introduction of new ways of heat management and other, often not yet fully explored, chemical conversion processes in which green electrons are used, but also the development of new materials including large-scale heating coils, easily chargeable battery systems as well as catalyst materials. For each of these developments, there is the issue of materials scarcity as well as durability as the introduction of these production processes should also be cost effective and overall more sustainable than the existing ones.

“…Although advanced reactor technologies are being developed to reduce the energy intensity and carbon emissions (Amghizar et al 2020), the process is still based on oil, while alternative sustainable biotechnological production systems do not exist. This scenario does not only apply to ethylene but describes the global challenge in general.…”

“…Current large‐scale ethylene production relies on steam cracking of petroleum‐derived materials, which requires high energy input and is one of the largest single CO 2 ‐emitting processes in chemical industry.

Ethylene is a volatile hydrocarbon with a massive global market in the plastic industry.The ethylene now used for commercial applications is produced exclusively from nonrenewable petroleum sources, while competitive biotechnological production systems do not yet exist. This review focuses on the currently developed photoautotrophic bioproduction strategies that enable direct solar-driven conversion of CO 2 into ethylene, based on the use of genetically engineered photosynthetic cyanobacteria expressing heterologous ethylene forming enzyme (EFE) from Pseudomonas syringae. The emphasis is on the different engineering strategies to express EFE and to direct the cellular carbon flux towards the primary metabolite 2-oxoglutarate, highlighting associated metabolic constraints, and technical considerations on cultivation strategies and conditional parameters. While the research field has progressed towards more robust strains with better production profiles, and deeper understanding of the associated metabolic limitations, it is clear that there is room for significant improvement to reach industrial relevance. At the same time, existing information and the development of synthetic biology tools for engineering cyanobacteria open new possibilities for improving the prospects for the sustainable production of renewable ethylene.

“…In 2017, 110 million tons of propylene were produced mainly by steam cracking and direct dehydrogenation of propane [1] . The production of C 2 to C 3 olefins is one of the most energy intensive sectors of the chemical industry [2,3] . Many important industrial compounds, like polypropylene, propylene oxide, isopropanol, acetone, are produced by chemical transformations starting with propylene [4] .…”

Oxygen‐Functionalized Boron Nitride for the Oxidative Dehydrogenation of Propane – The Case for Supported Liquid Phase Catalysis

et al. 2022

Boron and boron containing materials have created a new class of catalysts for the highly selective conversion of light alkanes to building block olefins. Boron oxide species seem to play an essential role for the oxidative dehydrogenation of propane. For boron nitride they are created through an induction process under reaction conditions. It is still not obvious how different kinds of oxidative pre-activation influences the observed activity and selectivity. Here we compare two different oxygen activation strategies of boron nitride, a classical activation by calcination at different temperatures and ball-milling with varying rotation velocity. These treatments allow to control the amount of introduced boron oxide species from 0.2 to 17.5 wt.-%, as quantified by alkalimetric titration. The catalytic experimental data together with the pre, post as well as in situ characterization, give insights how the catalyst's surface changes under reaction conditions. On this backdrop it can be deduced that molten boron oxide predominantly acts as catalyst under reaction conditions, and boron nitride as catalyst support.

Sustainable innovations in steam cracking: CO₂ neutral olefin production

Abstract: Steam cracking of hydrocarbons is and will be the main process to produce light olefins but emits large quantities of CO2. Enhancing heat transfer in the radiation section, using green energy and novel furnace designs will be key to substantially reducing CO2 emissions.
