摘要: The instant disclosure relates to a composition comprising potassium carbonate and calcium acetate, optionally along with sulfur containing compound. The composition of the present disclosure reduces coke formation during hydrocarbon cracking, particularly reduces surface coke and spalled coke during hydrocarbon cracking when compared to hydrocarbon cracking without the said composition. The disclosure further relates to a method for reducing formation and/or deposition of coke during pyrolysis or cracking of hydrocarbons.

摘要: The present disclosure provides a process for the preparation of butadiene from a mixed C4 feed stream comprising n-butane and n-butenes. The process involves separation of n-butane from the mixed C4 stream followed by oxidative dehydrogenation process. The water and fluid mediums are separated from the product C4 stream followed by separation of butadiene. The process of the present disclosure is cost effective, energy efficient, and provides high yield of butadiene.
