Catalytic Conversion Of Light Alkanes Research Articles

Application of co‐feeds in the catalytic conversion of light alkanes to aromatics: A comprehensive review

AbstractCatalytic conversion of light alkanes (C1‐C3) to aromatics offers an attractive valorization route for abundant gas resources and has been a prevalent topic of research over the past few decades. Despite considerable advancements in the understanding of these reactions, several fundamental and practical hurdles have prevented their industrial application. Among the numerous attempts to resolve these issues, co‐feeding certain additives yields promising results, including the activation of alkanes under milder conditions, an increase in catalytic stability, and a shift in product distribution towards more desirable compounds. Systematic studies have elucidated the precise working mechanism of the co‐feeds in aromatization systems, explaining the experimentally observed results. This review provides an extensive compilation of information on the application of co‐feeds in light alkane aromatization, which has accumulated in the literature since the pioneering reports in the 1990s. Detailed summaries are provided for each additive, ranging from hydrocarbons to oxidants. Viable strategies for future work in this field, aiming to bridge the gap between academic studies and industrial applications, are also discussed.

Recent Progress of Ga-Based Catalysts for Catalytic Conversion of Light Alkanes

The efficient and clean conversion of light alkanes is a research hotspot in the petrochemical industry, and the development of effective and eco-friendly non-noble metal-based catalysts is a key factor in this field. Among them, gallium is a metal component with good catalytic performance, which has been extensively used for light alkanes conversion. Herein, we critically summarize recent developments in the preparation of gallium-based catalysts and their applications in the catalytic conversion of light alkanes. First, we briefly describe the different routes of light alkane conversion. Following that, the remarkable preparation methods for gallium-based catalysts are discussed, with their state-of-the-art application in light alkane conversion. It should be noticed that the directional preparation of specific Ga species, strengthening metal-support interactions to anchor Ga species, and the application of new kinds of methods for Ga-based catalysts preparation are at the leading edge. Finally, the review provides some current limitations and future perspectives for the development of gallium-based catalysts. Recently, different kinds of Ga species were reported to be active in alkane conversion, and how to separate them with advanced in situ and ex situ characterizations is still a problem that needs to be solved. We believe that this review can provide base information for the preparation and application of Ga-based catalysts in the current stage. With these summarizations, this review can inspire new research directions of gallium-based catalysts in the catalysis conversion of light alkanes with ameliorated performances.
