Production of carbon 4 liquefied gas and straight-run gasoline for vehicle-use liquefied gas and 90-octane high-octane gasoline
Thread Content
How is the product distribution? What is the catalyst life?
1. The production of LPG for use in vehicles from C4 hydrocarbons does not require a catalyst; gas separation methods can be used for this purpose. The main challenges lie in controlling the total amount of olefins and sulfur, as well as limiting the amounts of C5 and C2 compounds… There are three different product grades available. 2. There are several methods and processes for producing 90# gasoline from straight-run gasoline: 1) Isomerization, 2) Aromatization, 3) Reforming, 4) Adding additives… It’s similar to mixing drinks, haha… These processes have been extensively discussed on this forum; the original poster is encouraged to browse and search more on the topic – no need to say anything further… :lol This post was last edited by wangsc on 2009-3-8 at 22:31
There is a type of non-hydrogenation reforming unit in which a single reactor (with a catalyst life that is renewable and a service life of over two years) has a production cycle of around 45 days; the ratio of product gasoline to liquefied gas is between 1.2:1 and 1.4:1. One such unit is available in Tianjin.
Which organization owns this facility in Tianjin?
1. The use of liquefied gas in vehicle fuel is a topic that is currently under much discussion; it refers to ordinary gas, and the process focuses on removing total olefins and total sulfur, with a yield of around 70–80%. . . 2. For the production of 90# straight-run gasoline, aromatization or isomerization is used; the liquid yield is approximately 85–95%, depending on the degree of purification. . . :lol
