Embodiment Construction

[0008] When using natural gas as raw material to produce methanol, dimethyl ether, and liquid hydrocarbons (GTL) and other products, it is necessary to first undergo the steam reforming reaction of natural gas to prepare H 2 , CO, CO 2 Synthesis gas with equal components, and then use this synthesis gas to further synthesize methanol, dimethyl ether, liquid hydrocarbons (GTL) and other products.

[0009] Due to the limitations of synthesis gas manufacturing technology and process, the composition of the prepared synthesis gas often does not meet the ideal requirements for the raw material gas in the subsequent synthesis process. For methanol synthesis, its hydrogen-carbon ratio coefficient R value [R=(H 2 -CO 2 ) / (CO+CO 2 )] is required to be excellent in the range of 2.05 to 2.15, and it meets the requirements of CO 2 The CO content is required to be as high as possible under the condition that the concentration is not lower than 5% (vol), and the synthesis gas produced b...

Abstract

This invention relates to a method for improving methanol yield, comprising: do one or multi counter-water gas transformation reactions to synthetic gas(comprising hydrogen gas, carbon monoxide,carbon dioxide) to optimize the modulation of each component, especially to improve the CO concentration, so as to improve the space-time yield of the following methanol synthesizing. This method is specially useful in the component ratio modulation of synthetic gas produced by natural gas and steam transformation, and can be used in optimization of synthesizing reactions of methanol, dimethyl ether, liquid hydrocarbons and carbonylation raw gas.

Description

Technical field: [0001] The technical field of the present invention is coal, petroleum, natural gas chemical industry field technical background: [0002] At present, the raw materials for producing methanol and other oxygenates in the world mainly include coal and natural gas. Natural gas is used as raw material to produce synthesis gas (hydrogen-carbon dioxide-carbon monoxide, etc.) by natural gas water vapor conversion reaction; the synthesis of oxygen-containing compounds such as methanol with coal as raw material mainly uses technologies such as water gas production to produce synthesis gas. The synthesis gas produced by the two methods is subsequently used in the synthesis of oxygen-containing organic compounds such as methanol. However, due to the traditional synthesis gas manufacturing technology and process, the ratio of the three components of hydrogen-carbon dioxide-carbon monoxide in the produced synthesis gas is not optimized for the subsequent synthesis react...
