Flexibility of hydrocracking
Thread Content
The book says that the products of hydrocracking have great flexibility. In what ways is this manifested? How is its flexibility achieved?
Please, experts, answer! ! ! ! !
Different target products can be produced by using different catalysts, with various feedstocks being used.
Without compromising safety and reliability, utilizing available pressure and infrastructure to increase processing capacity, enhance the ability to process difficult-to-convert raw materials, and improve raw material flexibility
Highly flexible catalysts can be used.
Not only that, but the product also offers great flexibility in adjustment
Flexibility should be multi-faceted; on one hand, different raw materials can be used； On the one hand, products of different standards can be produced according to production requirements ； Furthermore, the catalyst can be adjusted in terms of hydrogenation and cracking.
Flexibility is manifested in the following: 1. The range of raw materials that can be processed is quite wide; it can be heavy oils such as propane-deasphalted oil, as well as lighter types of oils! 2. That is, there are more products available, which allows for the production of more intermediate distillates as well as more light oils!
9# lj20052004 [/b You said, “It’s possible to produce more middle distillate oil as well as more light oil.” This should be achieved by adjusting the bed temperature; however, the range of variation in bed temperature is quite small. Does that mean the range of variation in the products is also small?
Flexible feedstock: it can be heavy fraction oils obtained from crude oil distillation, or residue oils (including deasphalted residue oils resulting from the solvent deasphalting of vacuum residue). Flexible production: The product yield can be controlled under different operating conditions, either to produce gasoline primarily, or low-ice-point jet fuel and low-flash-point diesel primarily, or for the production of lubricants.
