Abstract
Abstract A novel treated charge zeolite is prepared by treating charge zeolite (which is essentially free of Secondary Pores) with steam for 5-60 hours at 1000° F.-1500° F. Product is particularly characterized by increased Secondary Pore Volume (pores of diameter of 100A-600A) in amount of as high as 0.20 cc/g.

Claim 1
Independent Claim
132 words
A process for treating a charge liquid residual hydrocarbon having an initial boiling point, as determined by ASTM D-1160, of at least about 1000° F. which comprises contacting said charge liquid residual hydrocarbon with a zeolite characterized by (i) a Lattice Constant of 24.23-24.38 A, (ii) a Secondary Pore Diameter of 100-600 A, (iii) an Secondary Pore Volume of 0.05-0.15 cc/g, and a (iv) Secondary Pore Mode of 100-325 A, in an ebullated bed at 650° F.-850° F. and 1000-4000 psig in the presence of 1,000-50,000 SCFB of hydrogen thereby forming treated hydrocarbon of decreased average boiling point, lower density, lower sulfur content, and lower metal content than said charge; and recovering said treated hydrocarbon of decreased average boiling point, lower density, lower sulfur content, and lower metal content than said charge.

Dependent Claim
132 words
A process for treating a charge liquid residual hydrocarbon having an initial boiling point, as determined by ASTM D-1160, of at least about 1000° F. which comprises contacting said charge liquid residual hydrocarbon with a zeolite characterized by (i) a Lattice Constant of 24.23-24.38 A, (ii) a Secondary Pore Diameter of 100-600 A, (iii) an Secondary Pore Volume of 0.05-0.15 cc/g, and a (iv) Secondary Pore Mode of 100-325 A, in an ebullated bed at 650° F.-850° F. and 1000-4000 psig in the presence of 1,000-50,000 SCFB of hydrogen thereby forming treated hydrocarbon of decreased average boiling point, lower density, lower sulfur content, and lower metal content than said charge; and recovering said treated hydrocarbon of decreased average boiling point, lower density, lower sulfur content, and lower metal content than said charge.
Claim 3
Dependent Claim
121 words
A hydrocarbon cracking process which comprises contacting a charge hydrocarbon having an ibp, as determined by ASTM D-1160, of at least about 400° F. with a cracking catalyst containing a zeolite characterized by (i) a unit cell size of 24.23-24.38 A, (ii) a Secondary Pore Diameter of 100-600 A, (iii) an Secondary Pore Volume of 0.05-0.15 cc/g, and (iv) a Secondary pore Mode of 100-325 A; maintaining said charge hydrocarbon in contact with said cracking catalyst at cracking conditions of 900° F.-1100° F. thereby forming crackate characterized by decreased boiling point, decreased density, decreased metal content, and decreased slurry oil content; and withdrawing said crackate characterized by decreased boiling point, decreased density, decreased of metal content, and decreased slurry oil content.
