Light hydrocarbon isomerization method
A technology of isomerization and light hydrocarbons, which is applied in the field of isoparaffins, can solve the problems that the increase of octane number is obviously limited, the problem of accumulation of heavy components cannot be solved, and the problem of further improvement can not be achieved, so as to reduce carbon deposition The effect of reducing the speed and carbon deposition rate and high recycling rate

Embodiment 1
[0041] This embodiment adopts the process flow shown in the drawings. The following describes the composition and properties of light hydrocarbon raw materials, the main reaction conditions of isomerization, and the composition and properties of isomerized products:
[0042] 1. Composition and properties of light hydrocarbon feedstock
[0043] The composition of the light hydrocarbon feedstock is shown in Table 1.
[0044] Table 1
[0045] Component Mass fraction / % N-butane 2.60 Isobutane 0.30 N-pentane 23.54 Isopentane 9.56 Cyclopentane 1.39 N-hexane 32.66 Isohexane 22.13 Cyclohexane and methylcyclopentane 1.65 C7 and above hydrocarbons 2.02
[0046] The research octane number of the light hydrocarbon feedstock is 59.4. Since the current octane number requirements for gasoline products are relatively high, generally above 90, if the light hydrocarbon raw materials are directly mixed into gasoline products, the ...
