Title: Process for converting heavy hydrocarbon oil
Inventor: SUGHRUE EDWARD L II
IPC: C10G69/04
Filed: 1990-08-23
Abstract: ABSTRACT OF THE DISCLOSURE Heavy hydrocarbon oil, containing asphaltene, sulfur and metal contaminants, is hydrotreated in the presence of a hydrotreating catalyst having a small pore diameter in an initial process step to remove sulfur and metal contaminants. Removal of additional metal and sulfur contaminants is then accomplished in a second process step by solvent deasphalting, wherein the size of the pore diameter of the hydrotreating catalyst utilized in the initial hydrotreating step affects the metals reaction in the subsequent solvent deasphalting step. In a third process step the deasphalted oil is catalytically cracked substantially in the absence of added hydrogen to provide lower boiling hydrocarbon products.

Title: Exhaust nozzle including idle thrust spoiling
Inventor: TAYLOR JOHN B
IPC: F02K1/04
Filed: 1991-01-17
Abstract: Abstract A method and apparatus are disclosed for spoiling thrust from combustion gases discharged from an aircraft gas turbine engine at ground idle operating condition. The method comprises the step of positioning a secondary exhaust flap of the exhaust nozzle to form a diffuser for the combustion gases at the ground idle operating condition for maintaining attachment of the combustion gases along the secondary exhaust flaps for spoiling thrust. An exemplary and preferred exhaust nozzle is provided wherein the secondary exhaust flaps are positionable in part independently of primary exhaust flaps so that the primary and secondary flaps may be disposed together in different positions during ground idle, dry, and augmented operating conditions of the engine. Thrust spoiling allows the engine to be operated at relatively high core speeds for providing bleed-air at relatively high pressure or electrical power from a generator, or both, without attendant relatively high thrust from the engine at the ground idle operating condition.
