Embodiment 1
[0026]Take by weighing 150 grams of ZSM-5 molecular sieve (the mol ratio of silicon oxide and aluminum oxide is 1000), 125 grams of silica sol (40% SiO 2 ), 0.56 gram of aluminum sulfate, 10 gram of turnip powder and 50 gram of water were mixed evenly through extruding, and then dried at 80 degrees for 1 hour to obtain QT1, and its proportioning ratio is shown in Table 1.
[0027] Take by weighing 100 grams of QT1 and place it on a support separated from the bottom of the reactor, take tetrapropylammonium hydroxide (25%) and place it at the bottom of the reactor, then seal the reactor, and crystallize at 100°C for 180 hours to obtain the product, After washing and drying at 100-140° C. for 4-24 hours, calcining at 500-650° C. for 4-24 hours to obtain the sodium-type binder-free carrier NZ1. Na in NZ1 2 The content of O is less than 0.5%, and no ion exchange is required.
[0028] Soak 50 grams of HZ1 in 50 grams of cyclohexane solution containing 7.8 grams of ethyl orthosilic...
Embodiment 2～7
[0032] Obtain catalyst b~g according to the method identical with embodiment 1, relevant proportioning and composition can be seen in table 1~3, the evaluation condition of the adopted catalyst of following embodiment 2~7 and comparative example 1~2 is all the same as embodiment 1 Similarly, the reaction evaluation results are listed in Table 4.
Embodiment 8～12
[0040] Examples 8-12 are the reaction results obtained by using catalyst c, changing raw materials and process conditions, and their relevant parameters are listed in Table 5 and Table 6.
[0041] The C2-C20 materials in Examples 9 and 10 that do not contain aromatic hydrocarbons and propylene come from their reaction products. The starting materials in Examples 11 and 12 came from streams other than non-reaction products.
