The invention relates to the technical field of pulverized coal pyrolyzation and methanol production employing a natural gas and provides an integrated technology for pulverized coal pyrolyzation and methanol production employing a natural gas. The technology comprises the steps of partially oxidizing the natural gas and oxygen, generating a high-temperature synthesis gas, mixing and pyrolyzing the high-temperature synthesis gas and pulverized coal and generating a high-temperature oil gas and semicoke; cooling and separating the high-temperature oil gas, producing light oil, heavy oil and a high-hydrogen synthesis gas; andwashing off sulfur and carbon dioxide in the synthesis gas in a low-temperature methanol washing system, pressurizing the clean synthesis gas and entering into a methanol synthesis system for synthesizing crude methanol, producing qualified refined methanol from the crude methanol through a rectification system and feeding the refined methanol into a methanol storage tank. The technical problems that two sets of processes are required for pulverized coal pyrolyzation and methanol production employing the natural gas, the processes are complicated, devices are multiple, the investment is high, reaction catalyst consumption is high and feed gas utilization is low are avoided.
