7019 results about "Gasoline" patented technology

Gasoline (American English), or petrol (British English), is a colorless petroleum-derived flammable liquid that is used primarily as a fuel in spark-ignited internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, a 42-U.S.-gallon (160-liter) barrel of crude oil yields about 19 U.S. gallons (72 liters) of gasoline (among other refined products) after processing in an oil refinery, though this varies based on the crude oil assay.

Gaseous and liquid fuel injector

A hydraulically actuated dual fuel injector for an internal combustion engine. More particularly, the application pertains to a hydraulically actuated injector for injecting controlled quantities of a first fuel and of a second fuel into an internal combustion diesel engine at different times. A dual fuel injector comprising: (a) an injector body; (b) an inlet port in the injector body for enabling pressurized hydraulic fluid from a hydraulic fluid source to be introduced into the interior of the injector body, the hydraulic fluid being of sufficient pressure to maintain injection valves in the injector body in a closed position until actuated; (c) a first inlet port in the injector body for enabling a first fuel to be introduced into the interior of the injector body; (d) a first injection valve in the injector body connected to the second inlet port for controlling injection of the first fuel from the injector through a first fuel ejection port; (e) a second inlet port in the injector body for enabling a second fuel to be introduced into the interior of the injector body; (f) a second injection valve in the injector body connected to the second inlet port for controlling injection of the second fuel from the injector through a second fuel ejection port; (g) a first control valve which causes the hydraulic fluid to actuate the first injection valve; (h) a second control valve which causes the hydraulic fluid to actuate the second injection valve; (i) a metering device in the injector body for metering the amount of first fuel injected by the first injection valve; and (j) a seal in the injector body which prevents leakage of the second fuel into the first fuel.

Catalyst for preparing aromatic hydrocarbon through methanol conversion as well as preparation method and application thereof

The invention discloses a catalyst for preparing aromatic hydrocarbon through methanol conversion. The catalyst comprises a component A and components B, wherein the mass ratio of component A to components B is 0.25-4; the component A is a modified zeolite molecular sieve and comprises 80-99wt% of molecular sieves and 1-20wt% of molecular sieve modifiers; the components B are oxide loaded metallic elements and halogen and comprise 85-95wt% of oxide, 0.5-10wt% of total metallic elements and 0.1-5wt% of halogen; and the component A and the components B are formed through squashing or extruding after being mixed uniformly. The catalyst has the following characteristics that: (1) the total recovery of benzene, toluene and xylene is higher and selectivity is high; (2) the raw material treatment capacity is large; (3) the non-aromatic hydrocarbon liquid product can serve as the solvent oil or gasoline component; (4) C4 hydrocarbon and non-aromatic hydrocarbon liquid phase products in the gas phase product can circularly enter into the catalyst bed layer, thus not only balancing the reaction heat but also improving the total recovery of the aromatic hydrocarbon; and (5) the catalyst has high activity and long life.
