Embodiment 1

[0041] A. Synthesis of Directing Agents

[0042] The molar ratio composition of the directing agent is SiO 2 : Al 2 o 3 :Na 2 O: n-Butylamine: H 2 SO 4 :H 2 O=40:1:10:28:7.2:2800. The composition of the silicon source is: SiO 2 = 25.13%; Na 2 O = 8.12%; H 2 O=66.75% water glass, first take by weighing 600 grams of water glass, add 126.5 grams of n-butylamine and 1181.3 grams of deionized water to make A solution, put it into the synthesis kettle, under stirring at 300 rpm Stir evenly, then weigh 41.82 grams of aluminum sulfate, put it into a beaker containing 1561.4 grams of water, then add 15.8 grams of sulfuric acid, stir evenly with a glass rod, make B solution, and add it dropwise to the solution in the kettle , Then the still is sealed, continue to stir and start to heat up after 10-20 minutes. In the first step, the temperature is raised from room temperature to 120°C at a rate of 2°C / min for 20 hours, and in the second step, the temperature is raised to 165°C a...

[0052] A. Synthesis of Directing Agents

[0053] The raw material composition of the directing agent is SiO 2 : Al 2 o 3 :Na 2 O: 1.6-hexanediamine: H 2 SO 4 :H 2 O=60:1:13:32:3.3:3000. The composition of the silicon source is: SiO 2 = 25.13%; Na 2 O = 8.12%; H 2 O=66.75% water glass, at first take by weighing 600 grams of water glass, add 728.9 grams of deionized water and 149.9 grams of 1,6-hexamethylenediamine to make A solution into the synthesis kettle, at 300 rpm Stir evenly under stirring, then weigh 17.93 grams of aluminum nitrate, put it into a beaker with 1561.4 grams of water, then add 15.6 grams of sulfuric acid, stir it with a glass rod to make B solution, add it dropwise to the solution, then the kettle was sealed, and the temperature began to rise after continuing to stir for 10-20 minutes. In the first step, the temperature is raised from room temperature to 120°C at a rate of 2°C / min for 20 hours, and in the second step, the temperature is raised to...

Abstract

The invention discloses a preparing method of hydrocarbon based on once carbinol, which comprises the following steps: heating carbinol to reacting temperature; entering into the reactor with acid siallite zeolite molecular sieve catalyst; transmitting into hydrocarbon compound at 300-500 deg.c under 0.1-5.0 Mpa with the speed at 0.1-10.0h-1; cooling; separating the C5+ hydrocarbon product and gas phase part; entering gas phase in the compressor; making partial liquid leave system; adopting others as circulating material to blend with raw carbinol; returning to reactor to proceed next reaction.

Description

technical field [0001] The invention relates to a method for producing hydrocarbon products by one-step conversion of methanol, technical background [0002] At present, the international crude oil price continues to rise, and one of the important factors is the arrival of the foreseeable peak of oil production, which triggers an international upsurge of research on alternative energy technologies. my country's energy structure is characterized by rich coal, little gas, and oil shortage. Therefore, for our country, from the perspective of energy security strategy, the demand for developing alternative energy is more urgent. [0003] Methanol is the cornerstone of petrochemical industry. Through proper catalytic process, methanol can be converted into various products of petrochemical industry, such as ethylene, propylene, aromatic hydrocarbons, alkanes and mixtures of the above products. [0004] Methanol conversion to gasoline (MTG) technology is a methanol conversion tech...
