Abstract

See full text

A process and adsorption vessel are provided for adsorbing asphaltenes from a hydrocarbon stream. Additionally, a process and adsorption vessel are provided for steam cracking a hydrocarbon stream containing asphaltenes by adsorbing asphaltenes from the hydrocarbon stream prior to steam cracking. Asphaltene adsorption is achieved through a carbon adsorbent having at least 25% of total pore volume provided by pores with pore diameter in the range of 0.1 to 2.0 micrometers and an oil adsorption number of at least 200.
