Patent number: 7238636Abstract: A method is disclosed for modifying a catalytic molecular sieve for shape-selective hydrocarbon conversions comprises: a) selectivating said catalytic molecular sieve by contacting with a silicon-containing selectivating agent; and b) calcining the selectivated catalytic molecular sieve at high temperature calcination conditions comprising temperatures greater than 700° C., which conditions are sufficient to reduce acid activity as measured by alpha value and increase diffusion barrier of said catalytic molecular sieve as measured by the rate of 2,3-dimethylbutane uptake, as compared to the selectivated catalyst. Catalytic molecular sieves thus prepared, such as silica-bound ZSM-5, and their use in hydrocarbon conversion processes such as aromatics isomerization, e.g., xylene isomerization, ethylbenzene conversion and aromatics disproportionation, e.g., toluene disproportionation are also disclosed.Type: GrantFiled: July 23, 2003Date of Patent: July 3, 2007Assignee: ExxonMobil Chemical Patents Inc.Inventors: Jeffrey S.

Patent number: 6659581Abstract: An inkjet printhead assembly includes at least one inkjet printhead having nozzles and firing resisters. The inkjet printhead assembly includes fire pulse generator circuitry responsive to a start fire signal to generate fire signals, each having a series of fire pulses. The fire pulse generator circuitry generates the fire signals by controlling the initiation and duration of the fire pulses. The fire pulses control timing and activation of electrical current through the firing resisters to thereby control ejection of ink drops from the nozzles. One embodiment of the inkjet printhead assembly includes multiple printheads disposed on a carrier to form a wide-array inkjet printhead assembly.Type: GrantFiled: January 16, 2001Date of Patent: December 9, 2003Assignee: Hewlett-Packard Development Company, L.P.Inventors: Dennis J.

Publication number: 20030038058Abstract: This is a process for upgrading a petroleum naphtha fraction. The naphtha is subjected to reforming and the reformate is cascaded to a benzene and toluene synthesis zone over a benzene and toluene synthesis catalyst comprising a molecular sieve of low acid activity. The preferred molecular sieve is steamed ZSM-5. The benzene and toluene synthesis zone is operated under conditions compatible with the conditions of the reformer such as temperatures of above about 800° F. (427° C.). In one aspect on the invention, the benzene and toluene synthesis catalyst includes a metal hydrogenation component from group VII(B), specifically rhenium. In one mode of operation, the benzene and toluene synthesis catalyst replaces at least a portion of the catalyst in the reformer. The process produces a product containing an increased proportion of benzene, toluene, and/or xylenes, and a reduced portion of alkylated aromatics, as compared to reformate.Type: ApplicationFiled: August 2, 2002Publication date: February 27, 2003Inventors: Madhav Acharya, Jeffrey S.
