摘要： The present subject matter relates to a feed nozzle assembly 100 for atomizing a heavy hydrocarbon feed by mixing the hydrocarbon feed with a diluent and an atomizing media. The feed nozzle assembly 100 includes at least one primary mixing chambers 101 for receiving the liquid hydrocarbon feed and the diluent to create a primary mixture. The primary mixture is than forwarded to a secondary mixing chamber 102. The secondary mixing chamber extends to a tertiary mixing chamber 103. A steam inlet 110 is provided to inject streams of steam to the secondary mixing chamber 102 and to the tertiary mixing chamber 103 through a first opening and a second opening, respectively, located within the steam inlet 110.

摘要： The present invention relates to a fluidized catalytic cracking process for cracking hydrocarbon feed having organo-sulfur compound as an impurity, said process comprising: adding a heavy metal poisoned spent catalyst to an equilibrium catalyst to obtain a composite circulating catalyst, wherein the heavy metal poisoned spent catalyst is added in an amount to maintain the activity of the circulating catalyst; and obtaining a fluidized catalytic cracked product.The present invention further relates to fluidized catalytic cracked product obtained by the process of the present invention. The sulfur content of the fluidized catalytic cracked product mainly gasoline which is boiling in the range of C5-250° C. reduced by more than 20% (wt/wt). And Research Octane number of the fluidized catalytic cracked product is increased by more than 1 unit.
