International Classification:

C10G 29/20
C10G 47/02

US Classification:

208 28, 208 33, 208 36, 208108, 208 27

Abstract:

The invention relates to a process for preparing lube oil basestocks from lube oil boiling range feeds. More particularly, the present invention is directed toward a process wherein a wax containing feed is solvent dewaxed to produce at least a partially dewaxed lube oil boiling range stream, which is hydrodewaxed to produce a first lube basestock. The first lube basestock is added to an independently selected second lube basestock and additives to make a lubricating oil.

International Classification:

C10G 45/12

US Classification:

208 89

Abstract:

A diesel fuel product with beneficial cold flow properties can be produced. A suitable feedstock for forming a diesel boiling range product can be hydrotreated to have a sulfur content of at least about 100 wppm and then dewaxed. This two stage process can allow for production of an arctic or winter diesel without use of high pressures. Optionally, a divided wall column fractionator can be used to allow a single separation stage to handle the effluent from both the hydroprocessing and the dewaxing stages.

International Classification:

B01D 17/00

Abstract:

Systems and methods are provided for performing field enhanced separations on a feed, such as a petroleum feed, a refinery feed, or another type of hydrocarbonaceous feed. The system can allow for increased throughput of feed per volume of the separation device or system while performing a desired amount of field enhanced separation. The field enhanced separation can include separation by thermal diffusion, optionally enhanced by the presence of an electric field in the channel for performing the separation by thermal diffusion.

International Classification:

C12Q 1/68
G01N 33/68

Abstract:

Life-threatening traumas such as terrorist attacks, war, disasters, mental or physical assault, severe accidents and violence frequently provoke emotional and behavioral disturbances known as post-traumatic stress disorder (PTSD) and suicide related thereto. Accurate diagnosis and treatment planning for PTSD and suicide remain difficult. The discovery of specific markers creates new opportunities for more accurate clinical assessments identifying groups that may experience better outcomes when exposed to an intervention. The present invention provides a process of detection of P-11, UBE3A, STY1, EMAP-II, SIP1, ORC5L, DCX, SCYE protein in a biological sample of a subject suspected of suffering from PTSD and/or having suicidal tendencies, and provides additional PTSD markers which are specific to gender.
