A kind of sulfuric acid catalytic composite and its application in the production of alkylated gasoline

[0017] First, add 150mL of sulfuric acid containing 0.5wt% caprolactam into the stainless steel stirred tank through a pump, feed nitrogen to evacuate, and control the pressure of the reactor at 0.3MPa, start stirring, and the speed is 1000r / min. When the temperature of the reactor was 12°C, 100 mL of a mixture of isobutane and butene (1-butene, 2-butene or isobutene) with an alkene ratio of 100:1 was added via a pump. After reacting for 10.5 minutes, stop stirring, open the vent valve, turn on the stirring tank, add a certain amount of extractant, take samples, and analyze the content of each component in the product by chromatography.

[0019] First, add 150mL of sulfuric acid containing 10.0wt% caprolactam into the stainless steel stirred tank through a pump, pass through nitrogen to evacuate, and control the pressure of 0.3MPa in the reactor, start stirring, and the speed is 1000r / min. When the temperature of the reaction kettle was 12°C, 100 mL of a mixture of isobutane and butene with an alkene ratio of 50:1 was added through a pump. After reacting for 10.5 minutes, stop stirring, open the vent valve, turn on the stirring tank, add a certain amount of extractant, take samples, and analyze the content of each component in the product by chromatography.

[0021] First, add 150mL of sulfuric acid containing 1.0wt% caprolactam into the stainless steel stirred tank through a pump, pass through nitrogen to evacuate, and control the pressure of 0.3MPa in the reactor, start stirring, and the speed is 1000r / min. When the temperature of the reaction kettle was 5°C, 100 mL of a mixture of isobutane and butene with an alkene ratio of 10:1 was added via a pump. After reacting for 10.5 minutes, stop stirring, open the vent valve, turn on the stirring tank, add a certain amount of extractant, take samples, and analyze the content of each component in the product by chromatography.
