Abstract

The invention relates to the technical field of research on light hydrocarbon generation equipment and discloses a method for improving the surface stain resistance of a light hydrocarbon generation device. The method comprises the steps that firstly, the surface of a cavity of the generation device is deeply cleaned, and water-soluble and oil-soluble stains on the surface are removed; furthermoreoleic acid and kerosene are mixed according to a certain mass ratio, polyethylene polyamine is added, and a rheologically-permeable emulsion is prepared; and the molecular density of the metal surface can be increased due to the fact that the metal surface of the cavity is coated with a coating, meanwhile a basis is built for the stain-resistant painting coating, and the coating has the beneficial effects that the durability is extremely high, and continuous use can be achieved without polluting the cavity.

Description

technical field [0001] The invention belongs to the technical field of light hydrocarbon generator equipment research, and in particular relates to a method for improving the surface pollution resistance of a light hydrocarbon generator. Background technique [0002] "Hydrocarbons" are a series of substances composed of carbon and hydrogen mixed in different proportions. The lighter parts are called light hydrocarbons. The main component of natural gas is C1 methane, containing a small amount of C2 ethane. The main components of liquefied petroleum gas are C3 propane and C4 butane, which are gaseous at normal temperature and pressure, called gaseous light hydrocarbons. C5-C16 hydrocarbons are liquid at normal temperature and pressure, we call them liquid light hydrocarbons. The lightest part of liquid light hydrocarbons is C5 and C6, saturated C5 and C6 are the best raw materials for bubbling gas production, and the heavier part is gasoline, kerosene and diesel oil. Light...
