For rockets and space vehicles, propellants usually take up 2/3 or more of their total mass. Large upper-stage rocket engines generally use a cryogenic fuel like liquid hydrogen and liquid oxygen (LOX) as an oxidizer because of the large specific impulse possible, but must carefully consider a problem called "boil off," or the evaporation of the cryogenic propellant.
RP-1 (Rocket Propellant-1 or Refined Petroleum-1) and similar fuels like RG-1 and T-1 are highly refined kerosene formulations used as rocket fuel. Liquid-fueled rockets that use RP-1 as fuel are known as kerolox rockets. In their engines, RP-1 is atomized, mixed with liquid oxygen (LOX), and ignited to produce thrust.
Nitrous oxide fuel blend propellants are a class of liquid rocket propellants that were intended in the early 2010s to be able to replace hydrazine as the standard storable rocket propellent in some applications. In nitrous-oxide fuel blends, the fuel and oxidizer are blended and stored; this is sometimes referred to as a mixed monopropellant.
Steam reforming of natural gas is the most common method of producing commercial bulk hydrogen at about 95% of the world production [13] [14] of 500 billion m 3 in 1998. [15] At high temperatures (700–1100 °C) and in the presence of a metal-based catalyst , steam reacts with methane to yield carbon monoxide and hydrogen.
Kerosene is used in kerosene lamps and as a fuel for cooking, heating, and small engines. It displaced whale oil for lighting use. Jet fuel for jet engines is made in several grades (Avtur, Jet A, Jet A-1, Jet B, JP-4, JP-5, JP-7 or JP-8) that are kerosene-type mixtures. One form of the fuel known as RP-1 is burned with liquid oxygen as rocket ...
It turns out the DWP had hidden a methane leak at the Valley Generating Station. Sun Valley residents endured a methane leak for years. Now L.A. will pay them $60 million
OLCO Petroleum Group – 319 stations in Ontario and Quebec; Petro-Canada – 1323 stations and 200 Petro-Pass stations across Canada; some acquired from BP (1983), Petrofina (1981) and Gulf Oil in the 1980s; Pioneer Petroleum – 130 stations in Ontario; 7-Eleven brand gasoline; Shell Canada – Canadian unit of Shell with 1800 stations across ...
Environmental regulators have found explosive levels of methane in a popular Berkeley park. Regulators and the city are sparring over the source of the gas and what to do about it.
