Abstract:
A fuel composition comprising a non-combustible, substantially heat resistant pervious substrate and an amount of propylene glycol disposed on the substrate sufficient to fill the majority of the surface interstices present in the substrate and an apparatus for providing a heat source suitable for cooking comprising a container having a liquid impervious bottom wall and a peripheral side wall extending generally upward from the bottom wall to define a container mouth, a non-combustible, substantially heat resistant pervious substrate disposed in the container and propylene glycol disposed on the substrate.
Abstract:
A method for upgrading an aromatics-containing charge composition boiling in the gasoline boiling range comprises i) contacting the charge composition with a nitrating agent under nitrating conditions to form a product comprising nitrated aromatics; ii) hydrogenating a feed containing the product of i) under conditions sufficient to substantially reduce the nitro group of the nitrated aromatics so as to form a product comprising aromatic amines, water and heavy amines; and iii) removing the water and heavy amines from the product of step ii) to provide a gasoline boiling range product of an octane rating greater than the charge composition.
Abstract:
Liquid petroleum products are marked with markers having the formula: ##STR1## wherein the R.sub.1 's and the R.sub.2 's are the same or different and are each selected from --H and C.sub.1 -C.sub.7 alkyls; provided that at least one, and preferably both, R.sub.1 's are a C.sub.3 -C.sub.7 alkyl; and provided that the R.sub.3 's are the same or different and are selected from --H, --NO.sub.2, --Br, --F, --CN, and --Me; and provided that at least one R.sub.3 is selected from --NO.sub.2, --Cl, --Br, --F, and --CN.
Abstract:
A fuel for use independently of atmospheric air by reaction with an oxidizer, has a metal hydride as a solid fuel component mixed into an inert liquid fuel component and 1.5 to 5.0 weight percent of a stearate as part of the solid fuel component. The liquid fuel component is preferably an easy flowing paraffin into which the stearate and the solid fuel component are mixed to form a liquified fuel that will react with a liquid oxidizer. The mixing is preferably performed at a temperature above 100.degree. C. and at a reduced pressure less than 10.sup.5 Pa.
Abstract:
A high-energy-content fuel composition, for controlled-ignition internal combustion engines, contains quadricyclane (tetracyclo-[2.2.1.0-(2,6).0-3,5]-heptane), for which a new synthesis method is proposed.The use of the quadricyclane-containing fuel composition makes it possible a larger amount of energy to be available per each fuel volume unit, and favorably modifies the combustion kinetics in controlled-ignition internal combustion engines.
Abstract:
A method for the purification of fluids such as water, aqueous fluids and liquid fuels, comprises contacting said fluids with a solid material body of a novel alloy which comprises 50 to 60% copper, 20 to 28% zinc, 0.5 to 8% nickel, 0.005 to 2.5% aluminum, 7 to 15% manganese, and 1.3 to 4.5% tin, based on the total weight of the alloy.
Abstract:
A fuels conversion which consumes energy and produces an aqueous waste is combined with a pressurized wet combustion which charges the waste, converting its combustible contaminants to energy returned to the conversion, concurrently purifying the waste for use or disposal. The heating value of the contaminants may be supplemented by an extraneous fuel, using the waste as slurrying medium, so that the combination is made energy self-sufficient. Transfer of heat may be by direct contact between hot combustion products and fuel being converted. Other processes which produce aqueous waste and consume energy may similarly be combined with the wet combustion.
Abstract:
A furfural-containing middle distillate stream is separated by use of a polyethyleneimine membrane which has been cross-linked with a polyisocyanate or a poly(carbonyl chloride) cross-linking agent.
Abstract:
A method of reducing a viscosity of asphaltenic crude oils by incorporating into said crude oil an effective viscosity reducing amount of an oil soluble organic compound having at least one oleophobic and hydrophobic fluoroaliphatic group, and optionally a low viscosity diluent, and compositions thereof.
Abstract:
A novel fuel composition containing the alcohol-soluble portion of the product obtained as a result of the mild reaction of a lignin-containing material with nitric acid and a component selected from the group consisting of water, methanol, ethanol mixtures thereof, mixtures of lower alcohols and hydrocarbon fuel.
