Abstract: Heavy hydrocarbons are upgraded to higher value distillates in a hydrocarbon conversion process which employs several parallel reaction zones which each contain both hydrotreating and hydrocracking catalyst beds. The feed and liquid recycle from the bottom of the reaction zone is charged to the top of the uppermost catalyst bed. Hydrogen flow is countercurrent to the descending liquid, and products are removed overhead through vapor-liquid contactors. The flow of feed to one of the reaction zones is periodically stopped to allow sequential on-stream hydrogenative regeneration of the catalysts within the reaction zone.

Abstract: A process and apparatus for the recovery and purification of a contaminated refrigerant withdrawn from a refrigeration or refrigerant recovery system which employs a compressor and an adsorbent selective for the adsorption of halogenated hydrocarbons. The adsorbent is selected from the group consisting of silicalite, faujasites, steamed and rare earth exchanged zeolite Y, mordenite, ZSM-5 and mixtures thereof, and more particularly the group consisting of a low cerium rare earth exchanged zeolite Y-84, a low cerium rare earth exchanged zeolite LZ-210, Breck Structure Six, ECR-32, and mixtures thereof. A significant increase in the capacity of these adsorbents over conventional adsorbents combined with the use of novel process steps to recover, purify and return a purified refrigerant to the refrigeration system result in significant cost savings at reduced risk of release of halogenated hydrocarbons to the environment.

Abstract: The internal corrosion of metal mufflers used in conjunction with internal combustion engines is substantially retarded by maintaining in the external void space thereof an adsorbent mass of a combination of crystalline zeolites having the crystal structure of chabazite and the crystal structure of faujasite. These adsorbent compositions exhibit a synergistic effect on corrosion retardation. Novel muffler devices per se are also disclosed.

Abstract: The present invention provides a process for treating a natural gas stream comprising sending a natural gas stream to at least one membrane unit to produce a permeate stream containing a higher concentration of carbon dioxide and a retentate stream containing a lower concentration of carbon dioxide. Then the retentate stream is sent to an adsorbent bed to remove carbon dioxide and other impurities to produce a natural gas product stream. The regeneration gas stream is sent through the molecular sieve adsorbent bed to desorb the carbon dioxide. In one process flow scheme, the regeneration stream is combined with the permeate stream from the membrane unit. Then the combined stream is sent to an absorbent column to remove carbon dioxide from the permeate stream to produce a second natural gas product stream. In the alternative flow scheme, a second membrane unit is used to improve efficiency.

Abstract: Systems and processes for dehydration of a process stream in the production of motor fuel grade ethanol (MFGE) can include temperature controlled adsorption of water in the process stream, and heat pumping to transfer heat from the process stream to a heat sink using one or more stages of heat pumping. One stage of heat pumping can be achieved during the regeneration process of a temperature controlled adsorber by desorbing the adsorbed water at a thermal condition enabling useful heat recovery. Another stage of heat pumping can be achieved during the adsorption process of a temperature controlled adsorber by transferring the heat of water adsorption to a heat sink. The heat sink with respect to each stage of heat pumping can be a solids separation unit, such as a beer column.

Abstract: Heavy hydrocarbons are upgraded to higher value distillates in a hydrocarbon conversion process which employs several parallel on-stream reaction zones which each contain both hydrotreating and hydrocracking catalyst beds. The feed and liquid recycled from the bottom of the reaction zone is charged to the top of the uppermost catalyst bed. Hydrogen flow in the reaction zones is countercurrent to the descending liquid, and products are removed as vapor. The flow of feed to one of the reaction zones is periodically stopped to allow sequential on-stream hydrogenative regeneration of the catalysts within the reaction zones. This allows continuous commercial operation at conditions which are otherwise unfeasible.
