be used in the instant invention typical feedstocks include any heavy or synthetic oil fraction or process stream having a boiling point above 392 u00b0 f 200 u00b0 c such feedstocks include vacuum gas oils vgo heavy coker gas oil hcgo heavy atmospheric gas oil ago light coker gas oil lcgo visbreaker gas oil vbgo demetallized oils dmo vacuum residua atmospheric residua deasphalted oil dao fischer tropsch streams light cycle oil and light cycle gas oil and other fcc product streams the process can be used over a broad range of applications as shown in the following table the process of this invention is especially useful in the production of middle distillate fractions boiling in the range of about 250 700 f 121 371 c a middle distillate fraction is defined as having an approximate boiling range from about 250 to 700 f at least 75 vol preferably 85 vol of the components of the middle distillate have a normal boiling point of greater than 250 f at least about 75 vol preferably 85 vol of the components of the middle distillate have a normal boiling point of less than 700 f the term u201c middle distillate u201d includes the diesel jet fuel and kerosene boiling range fractions the kerosene or jet fuel boiling point range refers to the range between 280 and 525 f 138 274 c the term u201c diesel boiling range u201d refers to hydrocarbons boiling in the range from 250 to 700 f 121 371 c gasoline or naphtha may also be produced in the process of this invention gasoline or naphtha normally boils in the range below 400 u00b0 f 204 c or c 5 to 400 u00b0 f boiling ranges of various product fractions recovered in any particular refinery.
