The invention relates to a process for preparing a synthetic anionic sulphur-containing surfactant composition comprising the steps of:(a) providing a surfactant precursor which precursor has the general formula R-O-SO_(3)-H (I) or the general formula


A catalyst that is useful for the removal of arsenic from hydrocarbon feedstocks. The catalyst comprises an alumina support, underbedded molybdenum and phosphorus components, and an overlayer of a nickel component. The catalyst further has the unique property of having a surface nickel-to-molybdenum atomic ratio of greater than 1.8 with a bulk nickel-to-molybdenum atomic ratio of less than 2.2. The nickel accessibility factor of the catalyst is greater than 1.2. The catalyst is prepared by the application of two metals impregnation steps with associated calcination steps that in combination provide for the underbedded metals and overlayer of nickel.


The invention relates to a heat exchange device (1) comprising a channel wall (3) defining a flow channel (7) with an inlet for receiving a gas flow. The device (1) further comprises one or more heat exchange surfaces (5a - e) positioned inside the flow channel (3) creating different parallel flow paths for the gas flow through the flow channel (7), at least one of the heat exchange surfaces (5a e) embedding one or more flow paths for a fluid heat exchange medium. The one or more deflection elements (40) are positioned inside the flow channel (7) and are attached to the channel wall (3) to deflect the gas flow away from the channel wall (3).

The invention relates to a device and method for distributing a liquid and gas in a multiple-bed downflow reactor, such as a hydrocarbon processing reactor, like a hydrocracker. The device comprises respectively the method uses a distributor device comprising a substantially horizontal collecting tray provided with a central gas passage. Gas passing in downward direction through the central gas passage is forced into a swirling motion by a swirler. This swirling motion has a swirl direction around a vertical swirl axis so that the gas leaves the central gas passage as a swirl. At a location above the collecting tray, a quench fluid is ejected into gas in an ejection direction, which is, viewed in a horizontal plane, at least partly opposite to the swirl direction.

Presented is a method for preparing a gas separation membrane system. This method involves depositing a membrane layer of gas-selective metal upon a tubular porous support followed by annealing the resulting layer of gas-selective metal. The resulting annealed membrane layer of gas-selective material is polished under a controlled polishing condition with an abrading medium that includes a structured abrasive article comprising a backing having bonded thereto an abrasive layer comprising a plurality of shaped abrasive composites that comprise abrasive grains dispersed in a polymeric binder. Another layer of gas-selective metal is then deposited upon the tubular porous support. The cycle of annealing, polishing and depositing is repeated through one or more cycles until a leak-tight membrane system is provided.

The present invention provides a process for the production of furan, said process comprising the steps of: i) contacting furfural with a decarbonylation catalyst in a decarbonylation reactor to produce a gaseous decarbonylation reaction product stream comprising furan and carbon monoxide; ii) contacting said gaseous decarbonylation reaction product stream with a solvent stream comprising furfural; iii) absorbing at least a portion of the furan present in the gaseous decarbonylation reaction product stream into the solvent stream to provide a furan-containing solvent stream and a gaseous stream comprising carbon monoxide; iv) separating the furan from the furan containing solvent stream by distillation to provide a first furan stream; and v) using at least a portion of the remaining solvent stream comprising furfural as at least a portion of the furfural provided to the decarbonylation reactor.


An insulated electrical conductor (MI cable) may include an inner electrical conductor, an electrical insulator at least partially surrounding the electrical conductor, and an outer electrical conductor at least partially surrounding the electrical insulator. The insulated electrical conductor may have a substantially continuous length of at least about 100 m. The insulated electrical conductor may have an initial breakdown voltage, over a substantially continuous length of at least about 100 m, of at least about 60 volts per mil of the electrical insulator thickness (about 2400 volts per mm of the electrical insulator thickness) at about 1300 F (about 700 C) and about 60 Hz. The insulated electrical conductor may be capable of being coiled around a radius of about 100 times a diameter of the insulated electrical conductor. The outer electrical conductor may have a yield strength based on a 0.2% offset of about 100 kpsi.
