  • Publication number: 20250230110
    Abstract: The invention relates to a process for butane hydrogenolysis for producing one or more desired hydrogenolysis products. The process involves introducing an initial feed stream comprising a butane feed and hydrogen feed in a reactor system comprising a number of reactors, for example not more than 10 reactors, arranged in a series. Each of these reactors contain a butane hydrogenolysis catalyst loaded at specific catalyst loading in a manner such that every reactor apart from the first reactor in the series has higher catalyst loading than the catalyst loading of the immediately preceding reactor. Further, each of the reactors are configured to operate at a higher reactor temperature rise than the preceding reactor. The process may include the use of diluent, preferably methane, with the feed stream in one or more of the reactors. The invention further relates to a reactor system process for conducting the process for butane hydrogenolysis.
