Abstract
A kind of non-hydro isomerizaiton process is applicable to the octane value that improves the straight-run spirit cut.The technical characterstic of this technology is: isomerization reaction is that the selective splitting with content of wax diesel oil is reflected in the same reactor with carrying out simultaneously on a kind of catalyzer.This technical process is simple, less investment, and process cost is low, good product quality.
Description
The present invention relates to a kind of refining of petroleum method, be specifically related to a kind of non-hydro isomerizaiton process that is used to improve gasoline octane rating.
Existing isomerization process is UOP exploitation " a full isomerization process ", and this technological process is to finish facing under the condition of hydrogen.Therefore, invest huge, process cost costliness, flow process complexity.
Purpose of the present invention is that a kind of non-hydro isomerizaiton process will be provided, and its flow process is simple, less investment, and process cost is low.
The object of the present invention is achieved like this:
Non-hydro isomerizaiton process of the present invention comprises the process furnace heating of stock oil, stock oil selective splitting and isomerization reaction, and these two kinds of reactions are all carried out in fixed-bed reactor, and temperature of reaction is not higher than 450 ℃; Reaction is carried out under normal pressure; Reaction velocity was greater than 1 hour-1.
Stock oil of the present invention is composite by a certain percentage by straight-run spirit cut and content of wax diesel oil.Stock oil is heated to enter in the fixed-bed reactor that catalyzer is housed when the wax molecule can carry out the cracked temperature and reacts.Catalyzer is the ZSM-5 through modification.Continuous reduction with catalyst activity need improve constantly temperature of reaction to keep reaction depth.
Below in conjunction with accompanying drawing technology of the present invention is elaborated.
1 is raw oil pump among the figure, with it raw material (straight-run spirit cut and content of wax diesel oil distillate mix at 1: 1) is sent into process furnace 3, be heated to 250 ℃, enter reactor 4 under the effect of the ZSM-5 catalyzer after the modification from the top then, wax molecule in the raw material begins to be cracked into small molecules, and produces dehydrogenation reaction.And the normal paraffin in the straight-run spirit cut carries out isomerization reaction simultaneously.The bottom of reaction oil gas autoreactor 4 throws away, and enters separation column 5 and carries out fractionation and be divided into stop bracket gasoline and low freezing point diesel fuel
Technical process of the present invention is simple, less investment, and process cost is low, good product quality.Be suitable for the straight-run spirit cut and obtain high octane gasoline component by isomerization reaction.
