“…462,463 Nevertheless, we can suggest that SC, FCC and direct dehydrogenation can currently present the cheapest options for LO synthesis, while LOs produced in MTO seem more expensive. 464 The relatively low cost of olefins produced by SC and FCC is to a larger extent due to the high maturity of these technologies. In mid-term, cheap LO synthesis technologies could involve oxidative dehydrogenation in the chemical looping mode, methane coupling, methanol-mediated CO/CO 2 hydrogenation.…”

“…The light olefins produced, such as ethylene and propylene, are used as building blocks for chemicals, polymers, and fuels . Steam cracking (SC), also known as thermal pyrolysis, is currently the leading method for olefin production of ethylene and propylene and uses different types of hydrocarbons as feedstock, from natural gas liquids to petroleum liquids . Deep catalytic cracking (DCC) was also developed to utilize all parts of petroleum to increase the production of light olefins from heavy oil feedstock .…”

Sorption-enhanced catalysts are bifunctional materials consisting of a heterogeneous catalyst affixed to a solid sorbent with a combined capacity to selectively capture and convert CO2 directly to value-added fuels and chemicals in the same reactor. The benefits of facile separation of CO2, directly from air or from flue gas, and conversion to chemical commodities is appealing for developing an integrated carbon capture and utilization scheme. The growth of this area is rapidly expanding with interest from catalysis, materials design, and life-cycle analysis researchers. However, the promise of sorption-enhanced catalysts is limited by their reduced thermal stability, CO2 capture capacity, and restricted product streams to C1 hydrocarbons. The prime issue is that the reaction conditions for the capture of CO2, regeneration of the sorbent, and utilization can be vastly different. It remains a challenge to optimize both the properties of the sorbent support material and the heterogeneous catalyst used. This perspective summarizes the current state-of-the-art for the properties of solid sorbents, heterogeneous catalysts, and the combined sorbent-enhanced catalysts for producing hydrocarbons from CO2. Lastly, the perspective discusses challenges and future areas for improving the performance and capture efficiency of sorption-enhanced catalysts.

“…Propylene, as a key building block of the chemical industry, was produced globally at a scale of 130 million metric tonnes in 2019. 8 Propylene oxide is a major intermediate in the chemical industry for producing a large variety of consumer products including polyether polyols that are used in the manufacture of polyurethanes, propylene glycols as raw materials for the production of unsaturated polyester resins applied in the textile and construction industries, and propylene glycol ethers utilized as solvents in paints, inks, coatings and many other related applications. 9 Large-scale production of propylene oxide (globally approximately 10 million t/y in 2012) starts from propylene produced from crude oil fractions by steam cracking or fluid catalytic cracking (FCC).…”

The chemical industry faces the challenge of bringing emissions of climate-damaging CO2 to zero. However, the synthesis of important intermediates, such as olefins or epoxides, is still associated with the release of large amounts of greenhouse gases. This is due to both a high energy input for many process steps and insufficient selectivity of the underlying catalysed reactions. Surprisingly, we found that the oxidation of propane at elevated temperature over inert materials such as boron nitride and silicon dioxide leads to the formation of significant amounts of propylene oxide in a mixture with propylene, with unexpectedly small amounts of CO2 being formed. Fragile products are usually synthesised on highly specific surfaces, which is associated with strong interactions. We demonstrate that rapid reaction over unspecific interfaces entails im-portant consequences for the synthesis of products prone to overoxidation. Process simulations reveal that the combined synthesis of these two important chemical building blocks is technologically feasible. Our discovery leads the ways towards an environmentally friendly production of propylene oxide and propylene in one step. A complex catalyst development is not necessary.
