| 20080308460 | ENCLOSURE CONTAINING A GRANULAR BED AND A DISTRIBUTION OF A GAS PHASE AND OF A LIQUID PHASE CIRCULATING IN AN ASCENDING FLOW IN THIS ENCLOSURE - The present invention relates to an enclosure ( | 12-18-2008 |
| 208149000 | Solids of dissimilar composition | 1 |
| 20100147747 | Dewaxing catalysts and processes - A process for dewaxing a waxy component-containing hydrocarbon feedstock comprises contacting the feedstock under dewaxing conditions with a catalyst system comprising ZSM-48 and a molecular sieve of the MTT framework type. | 06-17-2010 |
| 208152000 | Solids replenishment, or selective discard | 1 |
| 20090032440 | METHOD OF TRANSFERRING PARTICLES FROM ONE PRESSURE ZONE TO ANOTHER PRESSURE ZONE - One exemplary embodiment can include a method of controlling a catalyst transfer vessel cycle of loading and unloading based on an expected level of a catalyst in a downstream vessel for a hydrocarbon conversion unit. The method can include calculating an expected catalyst level in the downstream vessel based on the unloading of the catalyst transfer vessel to adjust a setpoint to change the catalyst transfer vessel cycle of loading and unloading. | 02-05-2009 |
| 208153000 | Suspension system | 3 |
| 208157000 | Liquid feed | 2 |
| 20090314686 | SYSTEM AND PROCESS FOR REACTING A PETROLEUM FRACTION - In one exemplary embodiment, a system for reacting a first feed can include a petroleum fraction having at least about 90%, by volume, with a boiling point of at least about 300° C. The system can include a bubble column reactor. The bubble column reactor, in turn, can include a first inlet for the first feed and a second inlet for a second feed including a gas rich in hydrogen. In addition, the petroleum fraction may be in counter-current flow with respect to the gas rich in hydrogen inside the bubble column reactor. | 12-24-2009 |
| 20110073525 | APPARATUS AND METHOD FOR CONTROLLING OR ADDING MATERIAL TO ONE OR MORE UNITS - Material delivery systems and methods are disclosed. Material delivery system includes delivery vessel, metering device, dispense mechanism, and mixer. The delivery vessel is configured to dispense material to a unit and metering device provides a metric indicative of the dispensed material to the unit. The dispense mechanism is configured to couple the delivery vessel to the unit. The mixer is coupled to the delivery vessel and configured to sufficiently mix the material with an activating agent. The method includes dispensing metered material from a dispense mechanism of a delivery vessel coupled to a mixer, wherein a metric is indicative of the dispensed material to the unit; sufficiently mixing the metered material with an activating agent in the mixer to activate the material, the mixer coupled to the unit; and delivering the activated material to the unit via the mixer. Systems and method also include providing material to plurality of units. | 03-31-2011 |
| 208163000 | Fluidized dense bed | 1 |
| 208164000 | Solids transferring | 1 |
| 20090321319 | Multi-Staged Hydroprocessing Process And System - Methods and systems of processing a hydrocarbonaceous feed stock flows are provided. In one aspect, the method includes providing two or more hydroprocessing stages disposed in sequence, each hydroprocessing stage having a hydroprocessing reaction zone with a hydrogen requirement and each stage in fluid communication with the preceding stage. A hydrogen source is provided substantially free of hydrogen from a hydrogen recycle compressor. The hydrocarbonaceous feed stock flow is separated into an portions of fresh feed for each hydroprocessing stage, and then supplying the first portion of fresh feed with hydrogen from the hydrogen source in an amount satisfying substantially all of the hydrogen requirements of the hydroprocessing stages to a first hydroprocessing zone. | 12-31-2009 |
