Household 'ammonia' is a solution of NH 3 in water, and is used as a general purpose cleaner for many surfaces. Because ammonia results in a relatively streak-free shine, one of its most common uses is to clean glass, porcelain, and stainless steel. It is also frequently used for cleaning ovens and for soaking items to loosen baked-on grime.
The steam reforming, shift conversion, carbon dioxide removal, and methanation steps each operate at absolute pressures of about 25 to 35 bar, while the ammonia synthesis loop operates at temperatures of 300–500 °C (572–932 °F) and pressures ranging from 60 to 180 bar depending upon the method used. The resulting ammonia must then be ...
The table above gives properties of the vapor–liquid equilibrium of anhydrous ammonia at various temperatures. The second column is vapor pressure in kPa. The third column is the density of the liquid phase. The fourth column is the density of the vapor. The fifth column is the heat of vaporization needed to convert one gram of liquid to vapor.

[90] [91] Ammonia to hydrogen conversion can be achieved through the sodium amide process [92] or the catalytic decomposition of ammonia using solid catalysts. [93] The X-15 aircraft used ammonia as one component fuel of its rocket engine. Ammonia engines or ammonia motors, using ammonia as a working fluid, have been proposed and occasionally ...
Cooking oils include a wide range of products, from canola oil to olive oil, coconut oil and more. The nutritional pros and cons of cooking oils are a frequent subject of debate online, especially ...
When vegetable oil is used directly as a fuel, in either modified or unmodified equipment, it is referred to as straight vegetable oil (SVO) or pure plant oil (PPO). Conventional diesel engines can be modified to help ensure that the viscosity of the vegetable oil is low enough to allow proper atomization of the fuel.
