Ethylene is the most produced organic substance in world and a pillar chemical process industry. The production pathway energy intensive has corresponding high carbon footprint. This work explores, simulates, presents possibility of reforming fuel gas steam cracking furnace. Currently, methane (CH4) hydrogen (H2) from furnace outlet makes up source. If H2 by reformation current can cover demand...

Ethylene is one of the largest building blocks in petrochemical industry, mainly produced by steam cracking ethane derived from naphtha or shale gas at high temperatures (>800 °C). Despite its technical maturity and economic competitiveness, thermal highly energy-intensive. Herein, an electrochemically engineered direct conversion process to produce hydrogen ethylene using a planar protonic cer...

improvements in the properties of ordinary sidewall compound (nr/br) with the addition of epdm by reactive processing method were evaluated. the results show that ozone resistance of these sidewalls was improved with increased addition of epdm. also the tensile strength and elongation-at-break were increased in comparison with nrbrepdm compounds that were made by non-reactive processing. sem ph...

This article described the protective properties of Cr coatings with a barrier layer composed ZrO2/Cr multilayers deposited onto E110 zirconium alloy. The multilayer thickness 100, 250, and 750 nm single-layer (1.5 µm) ZrO2 were obtained by multi-cathode magnetron sputtering in Ar + O2 atmosphere. Then, cracking resistance oxidation behavior studied under conditions thermal cycling (1000 °C) ai...

Database cracking has been an area of active research in recent years. The core idea of database cracking is to create indexes adaptively and incrementally as a side-product of query processing. Several works have proposed different cracking techniques for different aspects including updates, tuple-reconstruction, convergence, concurrency-control, and robustness. However, there is a lack of any...

Abstract Fossil-based production of plastics represents a serious sustainability challenge. The use renewable and biogenic resources as feedstocks in the plastic industry is imminent. Thermochemical conversion enables molecular building blocks materials from widely available resources. Waste cooking oil (WCO) significant fraction these This work provides insights into thermochemical fatty acids...
