Light olefins are important organic building blocks in the chemicals industry. The main low-carbon olefin production methods, such as catalytic cracking and steam cracking, have considerable room for improvement in their utilization of hydrocarbons. This article provides a thorough overview of recent studies on catalytic cracking, steam cracking, and the conversion of crude oil processes. To maximize the production of light olefins and reduce carbon emissions, the perceived benefits of various technologies are examined. Taking olefin generation and conversion as a link to expand upstream and downstream processes, a targeted catalytic cracking to olefins (TCO) process is proposed to meet current demands for the transformation of oil refining into chemical production. The main innovations of this process include a multiple feedstock supply, the development of medium-sized catalysts, and a diameter-transformed fluidized-bed reactor with different feeding schemes. In combination with other chemical processes, TCO is expected to play a critical role in enabling petroleum refining and chemical processes to achieve low carbon dioxide emissions.

Olefin solution polymerization can be used to obtain high-performance polyolefin materials that cannot be obtained via other polymerization processes. Polyolefin elastomers (POE) are a typical example. Due to cost, only a few linear α-olefins (e.g., 1-butene, 1-hexene, and 1-octene) are used as comonomers in solution polymerization in industry. However, α-olefin comonomers with other structures may have different effects on polymerization in comparison with common linear ones. Moreover, the properties of the corresponding materials may differ significantly. In this work, copolymers of ethylene with linear and end-cyclized α-olefins are synthesized using a metallocene catalyst. The copolymerization of ethylene with linear α-olefins results in a higher turn-over frequency (TOF) and lower incorporation than copolymerization with end-cyclized α-olefins, which may indicate that end-cyclized α-olefins have a higher coordination probability and lower insertion rate. In this reaction, the comonomer is distributed randomly in the polymer chain and efficiently destroys crystallization. End-cyclized α-olefins exhibit a much stronger crystallization destructive capacity (CDC) in the copolymer than linear α-olefins, possibly because linear α-olefins act mainly in the radial direction of the main chain of the polymer, while end-cyclized α-olefins act mainly in the axial direction of the main chain.
