    摘要: A process for preparing an ethylene-rich composition from a C3-5 paraffinic feedstock is described. The C3-5 paraffinic feedstock is subjected to molecular redistribution via dehydrogenation to form olefins, metathesis of the olefins, and rehydrogenation of the olefins to form paraffins. The product stream includes ethane, which is isolated and sent to an ethane or ethane/propane cracker (or, alternatively, a flexi-cracker, although this is less cost effective) to yield an ethylene-rich composition. The product stream also includes C3-5 paraffins, which can be recycled, and C6+paraffins, which can be used, for example, as solvents. Alternatively, they can be isomerized to form gasoline additives, or can be converted to aromatic compounds by subjecting them to reforming conditions, for example using the AROMAX™ process or platforming or rheniforming conditions.

    摘要: A hydrocarbon conversion process comprises contacting a renewable feedstock under hydroprocessing conditions with a bulk catalyst to form oleochemicals such as fatty alcohols, esters, and normal paraffins. Advantageously, the reaction conditions can be selected to directly convert the renewable feedstock to the desired product(s).

    摘要: The present invention relates to a multistage reforming process to produce a high octane product. A naphtha boiling range feedstock is processed in a multi-stage reforming process, in which the process involves at least 1) a penultimate stage for reforming the naphtha feedstock to produce a penultimate effluent 2) a final stage for further reforming at least a portion of the penultimate effluent 3) a regeneration step for the final stage catalyst. The severity of the penultimate stage can be increased during final stage catalyst regeneration in order to maintain the target RON of the reformate product and avoid reactor downtime.
