The present invention is directed to a method for the prediction of coke morphology from feed characteristics using cross-polarized light optical microscopy, image segmentation, and statistical analysis.

Coke morphology by image segmentation

A hydrocracking catalyst comprising a zeolite beta having an average domain size from 800 to 1500 nm; a zeolite USY; a catalyst support; and at least one metal selected from the group consisting of elements from Group 6 and Groups 8 through 10 of the Periodic Table. The zeolite beta has an OD acidity of 20 to 50 &#x3bc;mol/g and the catalyst support comprises an amorphous silica aluminate and a second support material when the weight percentage content of the zeolite beta is less than the weight percentage of the zeolite USY, and, when the weight percentage content of the zeolite beta is greater than the weight percentage of the zeolite USY, the zeolite beta has an OD acidity of 20 to 400 &#x3bc;mol/g, the zeolite beta content is from 0.5 to 10 wt. % and the zeolite USY has an ASDI between 0.05 and 0.12 with a corresponding zeolite USY content of from 0 to 5 wt. %. A process for hydrocracking a hydrocarbonaceous feedstock using the catalyst is also described as is a method for making the hydrocracking catalyst.

Hydrocracking catalyst containing zeolite USY and low acidity and large domain size zeolite beta

A second-stage hydrocracking catalyst is provided, comprising: a) a zeolite beta having an OD acidity of 20 to 400 &#x3bc;mol/g and an average domain size from 800 to 1500 nm2; b) a zeolite USY having an ASDI between 0.05 and 0.12; c) a catalyst support; and d) 0.1 to 10 wt % noble metal; wherein the second-stage hydrocracking catalyst provides a hydrogen consumption less than 350 SCFB across a range of synthetic conversions up to 37 wt % when used to hydrocrack hydrocarbonaceous feeds having an initial boiling point greater than 380&#xb0; F. (193&#xb0; C.). A second-stage hydrocracking process using the second-stage hydrocracking process is provided. A method to make the second-stage hydrocracking catalyst is also provided.

Noble metal zeolite catalyst for second-stage hydrocracking to make middle distillate

A hydrocracking catalyst is provided comprising:

Middle distillate hydrocracking catalyst containing zeolite beta with low OD acidity and large domain size

A hydrocracking catalyst is provided comprising: a zeolite beta having an OD acidity of 20 to 50 &#x3bc;mol/g and an average crystal size from 300 to 800 nanometers; a zeolite USY; wherein a wt % of the zeolite beta is less than the wt % of the zeolite USY; a support comprising an amorphous silica aluminate and a second support material; and at least one metal selected from the group consisting of elements from Group 6 and Groups 8 through 10 of the Periodic Table. A process for hydrocracking a hydrocarbonaceous feedstock is provided, comprising: contacting the hydrocarbonaceous feedstock with the hydrocracking catalyst under hydrocracking conditions to produce a hydrocracked effluent that comprises middle distillates. A method for making the hydrocracking catalyst is also provided.
