The invention relates to a method for producing synthetic ammonia syngas from agricultural and forestry residues. The method includes: key step one, drying and grinding the agricultural and forestry residues into particles; key step two, converting the agricultural and forestry residues into biological oil through fast pyrolysis reaction; key step three, subjecting the biological oil to gasification reaction with a certain quantity of air and methane to generate primary product gas; key step four, subjecting the primary product gas to water gas conversion reaction with a certain quantity of vapor to obtain the synthetic ammonia syngas. By adoption of the technical route, recycling of the agricultural and forestry residues can be well realized, and the method accords with ideas of circulareconomy and social sustainable development. 本发明涉及种自农林废弃物生产合成氨粗原料气的方法。该方法依次遵循下列关键步骤：关键步骤①，农林废弃物干燥、粉碎为颗粒；关键步骤②，将农林废弃物颗粒通过快速热解反应转化为生物油；关键步骤③，生物油连同定量的空气、甲烷共同发生气化反应，生成初级产品气；关键步骤④，初级产品气连同定量的水蒸气共同发生水煤气变换反应，获得合成氨粗原料气。本发明提出的技术路线能够较好的实
