Embodiment 1

[0041] combined with figure 1 As shown, the liquefied petroleum gas raw material is pulled out from the tank 1 by the pump 2 and sent to the desulfurization refining tower 3 .

[0042] The bottom of the desulfurization refining tower 3 is a metal sieve plate 3-1, and 8-10 cm glass balls or metal balls 3-2 are piled up on the sieve plate 3-1, and metal oxides 3-3 (for iron oxide or iron oxide) are piled up on the balls. Metal oxides such as zinc oxide), until the top of the tower, there is a sieve plate 3-1 on the top of the tower to suppress the metal oxide 3-3, and accumulate 8-10cm glass or metal balls 3-2 on the top of the sieve plate 3-1, Metal ball 3-2 is common carbon steel.

[0043] The liquefied petroleum gas enters from the bottom of the refining tower 3, and contacts with the oxidized metals in the tower reversely. The hydrogen sulfide and polysulfides in the liquefied petroleum gas react with the oxidized metals, and the metal salts formed are removed and refined b...

Abstract

The invention provides automotive liquefied petroleum gas with low propane content and high olefin content, a preparation device and a process thereof. After liquefied petroleum gas undergoes a purification treatment to remove element sulfur, polysulfide, mechanical purities, water and oil stain in the liquefied petroleum gas, a substance which does not change the chemical property and the combustion property of the liquefied petroleum gas and can increase the pressure of the liquefied petroleum gas is added under the hermetic condition to increase the pressure between 0.2 and 0.5MPa. After the liquefied petroleum gas with low propane content and high olefin content is refined, the problem of automobile fuel consumption can be solved. The automotive liquefied petroleum gas solves the problem that the popularization and application of the automotive liquefied petroleum gas are affected and limited due to the shortage of national propane resources from the resource structure.

Description

technical field [0001] The invention provides a vehicle-use liquefied petroleum gas with low propane content and high olefin content, which is used as gas fuel for motor vehicles. The invention also discloses its preparation process, which is suitable for industrial production and belongs to the technical field of petrochemical production and processing. Background technique [0002] The liquefied petroleum gas (abbreviation: LPG) involved in the present invention is mainly derived from the by-products of petroleum processing in oil refineries, and this gas basically has the problems of low propane content and high olefin content. For a long time, there have been two kinds of prejudices in this technical field. One is that: the propane content value of the liquefied petroleum gas for vehicles must be higher than 45% before it can be used as a vehicle gas. The supply pressure of liquefied petroleum gas; the second is to break away from the "octane number" - an important techn...
