Process for converting C2 to C12 aliphatics to aromatics over a zinc-activated zeolite

Abstract: A catalytic process is provided for converting feedstocks containing C 2 to C 12 aliphatic hydrocarbons to aromatics by contacting said feedstocks, under conversion conditions, with a crystalline zeolite catalyst having a constraint index of about 1 to 12 and an alpha value of no higher than about 45, and a minor amount of an added metal consisting essentially of zinc, thereby converting the feedstock to aromatics.

Catalytic olefin upgrading process using synthetic mesoporous crystalline material

Abstract: A process for upgrading aliphatic feedstocks containing lower olefins employing new synthetic catalyst of ultra-large pore crystalline material. The new crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25° C., a hexagonal electron diffraction pattern that can be indexed with a d 100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units. A new process is provied for catalytic oligomerization of lower olefin component in paraffin-containing mixed aliphatic feedstock which comprises contacting the feedstock under catalytic conversion conditions with acid metallosilicate solid catalyst having the structure of MCM-41 with hexagonal honeycomb lattice structure consisting essentially of uniform pores in the range of about 20 to 100 Angstroms. The oligomerization reaction is very selective, especially when conducted at temperature of about 40° to 250° C., yielding branched intermediate olefins. Low severity reaction permits execellent conversion of lower olefins at pressure of about 100-13,000 pKa range and moderate space velocity. Oligomers of propene produced over MCM-41, when reacted under cracking/disproportionation conditions yield a propylene-rich mixture which is separated as a C 3 stream, and C 6 + isoalkenes are recovered in good yield.

Single horizontal wellbore process/apparatus for the in-situ extraction of viscous oil by gravity action using steam plus solvent vapor

Abstract: A conduction heating, gravity assisted, single well, process for removing viscous hydrocarbonaceous fluids from a reservoir penetrated by a horizontal wellbore. Steam and a gas soluble in hydrocarbon-aceous fluids are circulated into the wellbore at or below the reservoir pressure through an upper perforated conduit of the horizontal wellbore. Circulation is continued so as to allow steam to heat the reservoir by conductance while gas enters the hydrocarbonaceous fluids. Thus, heated hydrocarbon-aceous fluids having a reduced viscosity flow from the reservoir around the horizontal wellbore where the fluids are produced to the surface by a lower conduit within the horizontal wellbore. The lower conduit is open along its length so as to be in fluid communi-cation with the reservoir for the length of the horizontal wellbore.

Uniaxially shrinkable biaxially oriented polypropylene film

Abstract: A uniaxially heat-shrinkable, biaxially oriented, multilayer film having a polypropylene-containing core layer containing at least 70 wt. % of the multilayer film and at least one polyolefin-containing skin layer adjacent the core layer is prepared by biaxially orienting a coextrudate and thereafter orienting the coextrudate by stretching 10 to 40% in the machine direction. The core layer contains isotactic polypropylene, a modifier which reduces the crystallinity of the polypropylene-containing core layer and a nucleating agent. Such modifiers include atactic polypropylene, syndiotactic polypropylene, ethylene-propylene copolymer, propylene-butene-1 copolymer, ethylene-propylene-butene-1 terpolymer, and linear low density polyethylene. The nucleating agent improves long term dimensional stability. The skin layer can be high density polyethylene on both sides or high density polyethylene on one side and isotactic polypropylene on the other side.

High VI lubricant blends from slack wax

Abstract: Lubricant compositions comprise blends or mixtures of low viscosity, 3-8 cS e.g. about 5 cS(100° C.), HVI lube basestock with higher viscosity, 15 cS+e.g. 30+ cS(100° C.) HVI PAO lube basestock produced from slack wax by thermal cracking to alpha olefins followed by Lewis acid catalyzed oligomerization of the alpha olefin mixture to lube base stock. Blending these components in appropriate proportions produces lube basestock having viscosities in the range of 8-15 cS (100° C.) from which material suitable for the formulation of 10W-30 automobile engine lube can be produced. The blends are notable for exhibiting high VI values greater than that of either component of the blend.
