A method of upgrading refining streams with high polynucleararomatic hydrocarbon (PNA) concentrations can include: hydrocracking a PNA feed in the presence of a catalyst and hydrogen at 380&#xb0; C. to 430&#xb0; C., 2500 psig or greater, and 0.1 hrto 5 hrliquid hourly space velocity (LSHV), wherein the weight ratio of PNA feed to hydrogen is 30:1 to 10:1, wherein the PNA feed comprises 25 wt % or less of hydrocarbons having a boiling point of 700&#xb0; F. (371&#xb0; C.) or less and having an aromatic content of 50 wt % or greater to form a product comprising 50 wt % or greater of the hydrocarbons having a boiling point of 700&#xb0; F. (371&#xb0; C.) or less and having an aromatic content of 20 wt % or less.

Upgrading polynucleararomatic hydrocarbon-rich feeds

The precursor of a hydroprocessing catalyst is made by impregnating a metal oxide component comprising at least one metal from Group 6 of the Periodic Table and at least one metal from Groups 8-10 of the Periodic Table with an amide formed from a first organic compound containing at least one amine group, and a second organic compound containing at least one carboxylic acid group. Following impregnation heat treatment follows to form in situ generated unsaturation additional to that in the two organic compounds. The catalyst precursor is sulfided to form an active, sulfide hydroprocessing catalyst.

Hydroprocessing catalysts and their production

Systems and methods are provided for slurry hydroconversion of a heavy oil feed, such as an atmospheric or vacuum resid. The systems and methods allow for slurry hydroconversion using catalysts with enhanced activity. The catalysts with enhanced activity can be used in conjunction with demetallization catalysts or catalysts that can be recycled as a side product from a complementary refinery process.

Slurry hydroconversion with high activity catalysts

A pacemaker optimising apparatus comprising: a component () which noninvasively or invasively monitors a haemodynamic measurement continuously in an individual and a processor () for receiving the haemodynamic measure and generating a pacemaker programming signal in response to this. There is also provided a communication device () for sending the pacemaker programming signal to the control system of the pacemaker (). There is also a method for an efficient process by which this apparatus can automatically use the haemodynamic measurements to determine the ideal settings for a particular pacemaker in a particular individual, and to updates the pacemaker's settings accordingly.
