Embodiment 1

[0009] Example 1: The dehydration hydrocarbon production system produces 10,000 tons of gasoline and liquefied gas per year, and consumes 25,000 tons of methanol. It can be equipped with a reforming system with an annual consumption of 25,000 tons of methanol to produce 34,000 tons of food-grade carbon dioxide, and the rest is hydrogen, more than 5,000 tons, for the production of thermal power and other purposes. It is suitable for building in small towns or supporting beverage and food enterprises.

Embodiment 2

[0010] Example 2: The dehydration hydrocarbon production system produces 100,000 tons of clean gasoline and liquefied gas annually, and consumes 250,000 tons of methanol. It can be equipped with a reforming system with an annual consumption of 250,000 tons of methanol to produce 340,000 tons of carbon dioxide, some of which are used to produce food-grade carbon dioxide and other carbon dioxide products of various specifications, and some can be transported back to the methanol plant for recycling methanol production. More than 50,000 tons of hydrogen can be used to produce thermoelectricity, and can also be refined for other purposes. It is suitable for supporting services for central cities and development zones.

Abstract

The invention relates to a combined production device of hydrocarbon production through methanol dehydration and hydrogen and carbon dioxide production through methanol reforming, which is characterized in that methanol is utilized as raw materials to co-produce petroleum, liquefying gas, hydrogen and carbon dioxide; heat generated during hydrocarbon production through methanol dehydration is used for a methanol reforming process; water generated during the hydrocarbon production through the methanol dehydration is used for the methanol reforming process; hydrogen generated by reforming can be used for a thermoelectric device and the like, and generated carbon dioxide is recovered and can be used for producing products such as food grade carbon dioxide and the like. The raw material methanol has rich sources. Petroleum and liquefying gas products satisfy the standards of clean fuel and has large product market demands. The hydrogen generated by a methanol reforming device is used as fuel and can realize near zero carbon dioxide emission in a thermoelectricity generation process.

Description

Technical field [0001] The invention relates to the technologies of methanol dehydration to hydrocarbon, methanol reforming to hydrogen and carbon dioxide recovery and utilization. Background technique [0002] The United States Mobile Company published methanol-to-gasoline technology in 1976. The process is as follows: firstly, coal or natural gas is used as raw material to produce synthesis gas, synthetic gas is used to synthesize crude methanol, and finally clean gasoline is produced by dehydration of crude methanol. In 1984, a fixed bed demonstration plant was established in Germany. In 1985, a methanol-to-gasoline industrial plant using natural gas as raw material was established in New Zealand. The Shanxi Coal Chemical Institute of the Chinese Academy of Sciences has proposed a patented technology for one-step methanol-to-gasoline production. The dehydration of methanol to hydrocarbons is completed in one step in one reactor to make the process simple and compact. De...
