Embodiment 1
[0025] Isobutanol and high-octane gasoline component oil raw materials: 700-970 parts by weight of methanol, 10-30 parts by weight of chain extender, 30-300 parts by weight of naphtha, and 1-3 parts by weight of catalyst molecular sieve.
[0026] The method for preparing above-mentioned isobutanol and high-octane gasoline component oil may further comprise the steps:
[0027] Step 1: Add 1%~3% of the chain extender nano light-burned basic magnesia to 99.9% coal-to-methanol at room temperature, stir and mix for 2 hours, stand still and continue to react for 24 hours, and partially react into isopropanol and Isobutanol.
[0028] Step 2: Add the straight distilled naphtha from crude oil with a distillation range of 70-170°C and an octane number of about 60 to the mixed liquid that has been reacted with light-burned basic magnesium oxide extender and 99.9% coal-to-methanol, and heat 90-100 ° C to make a mixed gas;
[0029] Step 3: The mixed gas is reacted with a molecular formul...
Embodiment 2
[0031] Isobutanol and high-octane gasoline component oil raw materials: 800 parts by weight of methanol, 30 parts by weight of chain extender, 200 parts by weight of naphtha, and 2 parts by weight of molecular sieve catalyst.
[0032] Step 1: Add 1%~3% of the chain extender nano light-burned basic magnesia to 99.9% coal-to-methanol at room temperature, stir and mix for 2 hours, stand still for 24 hours, and partially make isopropanol and Isobutanol;
[0033] The second step: add hydrogenated naphtha to the methanol mixture after the reaction of nano light-burned basic magnesium oxide, and heat it to 90-100°C to make a mixed gas;
[0034] The third step: the mixed gas is reacted with ZSM-5 zeolite solid acid catalyst to produce 4.6% isopropanol, 40% isobutanol, 27% light aromatics and 22% isoparaffins, and the product yield is 93.6%.
Embodiment 3
[0036] Isobutanol and high-octane gasoline component oil raw materials: 700 parts by weight of methanol, 30 parts by weight of chain extender, 300 parts by weight of light hydrocarbons, and 2 parts by weight of molecular sieve catalyst.
[0037] The first step: add 1%~3% of the chain extender nano light-burned basic magnesium oxide to 99.9% coal-based methanol at room temperature, stir and mix for 2 hours, and continue to react for 24 hours to make a mixture containing part of isopropanol and In modified methanol of isobutanol;
[0038] Step 2: Add the light hydrocarbons separated from the natural gas condensate into the 99.9% coal-to-methanol mixture that has been reacted with nano light-burned basic magnesium oxide, and heat it to 90-100°C to make a mixed gas;
[0039] The third step: the mixed gas is catalyzed by ZSM-5 zeolite solid acid fixed bed to produce oil containing 4.6% isopropanol, 45% isobutanol and 47% light aromatics, isoparaffins, and high-octane gasoline compo...
