Beschreibung
Zusammenfassung:	The invention discloses a system for preparing green methanol by coupling biomass gasification with green hydrogen. The system comprises a gasification unit (A), a purification unit (B), a hydrogen and oxygen unit (C) and a synthesis unit (D), synthesis gas (104) generated by the gasification unit (A) passes through the purification unit (B) and then passes through raw material gas (107) of the synthesis unit; oxygen (109) produced by the oxyhydrogen unit (C) is used as oxygen of the gasification unit, and hydrogen (113) produced by the oxyhydrogen unit (C) is used as a hydrogen source for adjusting the hydrogen-carbon ratio of raw material gas of the synthesis unit (D); part of purge gas (121) of the synthesis unit (D) is returned to the gasification unit for recycling. The system is stable and reliable in operation, high in renewable carbon source utilization rate and low in methanol preparation cost. 本发明公开了一种生物质气化耦合绿氢制绿色甲醇的系统，包括：气化单元（A）、净化单元（B）、氢氧单元（C）、合成单元（D）；所述的气化单元（A）所产生的合成气(104)通过净化单元（B）后合成单元的原料气(107)；
