Gas-cooled methanol reactor

Abstract

The invention belongs to the coal-to-methanol field, and concretely discloses a gas-cooled methanol reactor. The reactor comprises a cylinder, an upper seal head packaged at the top of the cylinder and a lower seal head packaged at the bottom of the cylinder, the cylinder, the upper seal head and the lower seal head form a closed cavity, reaction tubes are arranged in the cavity, the top of each of the reaction tubes is inserted to a mixed gas tank, the middle of each of the reaction tubes is inserted to a tube support, and the bottom of each of the reaction tubes is inserted to a tube plate; tube supports are fixed on the reaction tubes, the bottom of the tube plate is fixed at the top of a U-shaped cylinder, the bottom of the U-shaped cylinder is fixed on a branch tube, the bottom of the branch tube is inserted to a manifold trunk, the top of a distribution tube is inserted to the manifold trunk, the bottom of the distribution is positioned outside the manifold trunk, and the bottom of an adaptor penetrates through the lower seal head; the top of the upper seal head is provided with a work starting gas inlet; and the bottom of the lower seal head is provided with an outlet collector, and the bottom of the outlet collector is provided with a generated gas outlet. The reactor has the advantages of methanol output improvement, cost reduction, energy saving and energy consumption reduction.

Description

technical field [0001] The invention belongs to the field of coal-to-methanol, in particular to an air-cooled methanol reactor. Background technique [0002] Methanol (molecular formula: CH 3 OH) is an important organic chemical raw material and high-quality fuel, mainly used in the manufacture of acetic acid, formaldehyde, ethers and other organic products, and can also replace gasoline as a fuel. There are many ways to produce methanol. At present, the pressurized catalytic hydrogenation of carbon monoxide and carbon dioxide is almost always used in industry to synthesize methanol. The typical process includes raw material gas production, raw material gas purification, methanol synthesis, crude methanol rectification and other processes. Natural gas, naphtha, heavy oil, coal, and acetylene tail gas can all be used as raw materials for the production of methanol synthesis gas. In recent years, natural gas is mainly used as raw material to produce methanol in foreign countr...

Problems solved by technology

The current water-cooled and air-cooled reactors, but due to the high cost of equipment manufacturing and high catalyst costs, some of them cannot reach the production capacity after operation.
