A system and method are provided for self-application of a variety of face and body treatments. Specifically, the system includes a portable control-and-power console (70) and a light-weight portable device having a plurality of spouts (12), designed for different portions of the body, and comprising different features. The different features are adapted for different modes of treatment, such as suction massage treatment (12), lower-chin firming treatment (39), breast firming treatment (31, 33) warming light treatment (46), UV light treatment (46), LLLT (46), ultrasound treatment (60), pulsating magnetic field treatment (62), constant magnetic field treatment (62), electrostimulation treatment (27), cooling-diode treatment (47), warming-diode treatment (47), mechanical epilation (124), and photoepilation (110). Additionally, each spout (12) includes at least two, and preferably three or more features, for applying different modes of treatment, in tandem or in sequence, in accordance with predetermined schedules.

System and method for face and body treatment

A hydrocarbon composition comprises at least 90 wt. % of C 9 to C 20 non-normal olefins, non-normal saturates or combinations thereof based on the weight of the hydrocarbon composition, at least 2 wt. % and not greater than 25 wt. % of C 9 hydrocarbons based on the weight of the hydrocarbon composition, and less than 15 wt. % of C 17 + hydrocarbons based on the weight of the hydrocarbon composition, wherein said hydrocarbon composition has a specific gravity at 15° C. of at least 0.730 and less than 0.775. The composition is produced by oligomerization of at least one C 3 to C 8 olefin and an olefinic recycle stream containing no more than 10 wt. % of C 10 + non-normal olefins. The composition is useful in producing fuel blends, such as jet fuel and diesel fuel.

A hydrocarbon fluid composition that comprises species of at least two different carbon numbers, an aerobic biodegradability of greater than 40% at 28 days, a cetane number of less than 60, and a certain boiling point range; and a process for making the hydrocarbon fluid composition.

Olefin oligomerization and biodegradable compositions therefrom

A feedstock containing at least 1 wt % butenes, at least 1 wt % pentenes, at least 1 wt % hexenes, at least 10 wppm C 4 dienes, at least 10 wppm C 5 dienes, and optionally at least 10 wppm C 6 dienes can be selectively hydrogenated over a catalyst (e.g., a noble metal) to form a stream containing 100 wppm to 4000 wppm total dienes. The hydrogenated stream, and an olefinic recycle stream having less than 10 wt. % C 1+ moieties, can be contacted with a molecular sieve catalyst, e.g., at a recycle to feed ratio between 0.1 and 3.0, at a WHSV of at least 1.0 based on olefin in the feed, and at a reactor ΔT no greater than 40° F. (22° C.), thus forming a reaction product that can then be separated into a distillate, e.g., having from 1 wt % to 30 wt % non-normal C 9 olefins, and the aforementioned olefinic recycle stream.

This invention relates to oil refining, more particularly to a composition of a heavy fuel oil for use in marine power units and boiler plants. The fuel comprises, in percent by weight: an extract from the selective extraction of gas oil—(3-5), heavy catalytic cracking gas oil—(3-10), vacuum gas oil—(5-10), tar or topped residuum—(3-10), straight-run black oil—(10-20), viscosity breaking residue of heavy oil fractions—the rest. The selected combination of the components and their ratio may for example, result in a stable heavy fuel oil having improved viscosity properties. The inclusion of the above components into the fuel composition may also make it possible to expand the production of heavy fuel oils produced.
