Embodiment 1
The mixture of hydrocarbons, the composition of C3-C5 olefins is shown in Table 1 below:
Table 1
[0109]
[0110]
[0111] The feed ratio of maintaining the acid-hydrocarbon ratio of 0.9:1 is passed through the feed port of the alkylation reactor with 95 wt% sulfuric acid, respectively,
It is sprayed into the cavity of the alkylation reactor, mixed at a high speed under the action of the high-speed rotating rotor, and sent to the shell under the action of centrifugal force.
body movement. During this process, the mixed material is affected by the centrifugal force field and is disturbed by the high-speed shearing of the stator and rotor layer by layer.
Mixing and redistribution occur many times, and the dispersed form is very small droplets or very thin liquid films. When the reaction temperature of the system is 0 °C, the reaction
When the pressure system is controlled at 0.37MPa, part of the hydrocarbons in the droplets or liquid film flashes, taking away the heat of ...
Embodiment 2
[0123] The feed system adopts a volume concentration of 30.77% propane, 61.53% isobutane and 7.70% C3-C5 olefins
[0128] The RON value of the alkylation reaction product obtained by this process is 100.6.
