“…In order to improve heat removal from the SILP catalyst, this work was later extended to fluidized bed reactor technology. 183 The better heat removal in the fluidized bed improved catalyst stability and allowed for a more detailed investigation of the deactivation mechanism. Based on kinetic studies, a second order deactivation mechanism was proposed, in which two nickel complexes dimerized if the supply of ethylene was insufficient.…”

Brought to life more than half a century ago and successfully applied for high-value petrochemical intermediates production, nickel-catalyzed olefin oligomerization is still a very dynamic topic, with many fundamental questions to address and industrial challenges to overcome. The unique and versatile reactivity of nickel enables the oligomerization of ethylene, propylene and butenes into a wide range of oligomers that are highly sought-after in numerous fields to be controlled. Interestingly, both homogeneous and heterogeneous nickel catalysts have been scrutinized and employed to do this. This rare specificity encouraged us to interlink them in this review so as to open up opportunities for further catalyst development and innovation. An in-depth understanding of the reaction mechanisms in play is essential to being able to fine-tune the selectivity and achieve efficiency in the rational design of novel catalytic systems. This review thus provides a complete overview of the subject, compiling the main fundamental/industrial milestones and remaining challenges facing homogeneous/heterogeneous approaches as well as emerging catalytic concepts, with a focus on the last 10 years.

“…In line with sustainable chemistry principles, research attention has been focused on the development of heterogeneous processes for ethylene dimerization. Various families of solid catalysts have been investigated: (i) complexes immobilized on polymers and oxides, ,− (ii) metal–organic framework (MOF) and covalent organic framework (COF) materials, − and (iii) nickel and palladium supported on inorganic porous materials. − …”

“…Wasserscheid’s research group used ionic liquids supported on silica to immobilize cationic Ni complexes. , These multifunctional materials were tested as heterogeneous catalysts in a continuous gas-phase process for converting ethylene into 2-butene by dimerization/isomerization reactions. The typical conditions were an ethylene pressure of 1 bar, a contact time of 8 s, and an ethylene flow rate of 23.1 NmL min –1 .…”

With stricter ecological regulation and reduction of fossil feedstock, the research works have been oriented to renewable resources. Various bio-based molecules have been proposed for replacing the platform chemicals based on crude oil, but there are not yet well-established processes for producing these chemicals at large scale. As a result, in the short to midterm, a main impact will be expected from the production of bio-based bulk chemicals having identical structures as today’s bulk chemicals, including ethylene, which is a key intermediate for the production of platform molecules. The commercial method for producing ethylene is based on steam thermal cracking, but emerging methods using alternative sources (natural gas, coal, biomass) are very promising processes. For example, the high-volume production of ethylene by ethanol dehydration has become an economically feasible application. This perspective summarizes the advances in catalysts, processes, and fundamental understanding of reaction mechanisms in ethylene conversion to other high-value hydrocarbons, including propylene, butenes, and BTX aromatics.

“…Based on kinetic studies, a second order deactivation mechanism was proposed in which two nickel complexes dimerize if the supply of ethene is insufficient. 80 A completely different application of the SILP approach has been used for the design of enzymatic reactions. Lozano and co-workers have evaluated the immobilisation of free Candida antarctica lipase B (Novozyme 525L) by adsorption onto 12 different silica supports surface-modified with specific side chains (e.g.…”
