Low-temperature upcycling of polyolefins into liquid alkanes via tandem cracking-alkylation. Science. 2023 Feb 24;379(6634):807-811. doi: 10.1126/science. The mixture of C5-C10 hydrocarbons obtained directly from the distillation of crude oil contains a high proprtion of straight-chain alkanes. However, if this ... An alkane X dissociates to form methane ( C H 4 ) , ethene ( C 2 H 4 ) and propene ( C 3 H 6 ) . The mole fraction of ethene is 0.5, which means that its amount ... ... alkane. Concurrently, selectivities to terminal cracking and dehydrogenation decrease relative to central cracking because ΔSint‡ decreases for the former ... During a cracking reaction, hydrocarbons are generally decomposed into shorter alkanes and alkenes. Hydrocarbon fuels (like those produced by fractional ... ... Cracking, Turboquenching, and Electric Cracking, as illustrated in the Figure. ... IMPROVED SHALE GAS ALKANE DIRECT ALKANE AROMATIZATION CATALYST. highlight4 ... Cracking is a significant process in the petrochemical industry, where long-chain hydrocarbons, such as alkanes, are broken down into smaller, more useful ... May 14, 2010 ... The apparent rate coefficient for alkane cracking was described as the product of the number of alkane molecules per unit mass of zeolite that ... ... cracking processes e.g., steam cracking) with el ectrically driven thermocatalytic activation of alkanes to produce chemical building blocks allowing ... ... cracking of alkanes and alkenes. Before simulating hydrocarbon cracking reactions at elevated temperatures, MD calculations were performed to investigate ...
