一种桑枝生物燃料制备方法

本发明公开一种桑枝生物质燃料制备方法，属于桑枝废弃物资源化利用领域。步骤为：S1.废弃桑枝晾干、破碎成粉粒并收粉尘；S2.菌棒废渣用碳酸钠浸泡过滤，得MPR碱解液与MPR滤渣，MPR滤渣加纤维素酶解，得MPR酶解残基、第一MPR酶解液，冷凝酶解蒸汽得第二MPR酶解液；S3.桑枝粉热风干燥，喷第二MPR酶解液稀释液调含水率12%~14%，收尾气冷凝水；S4.加MPR酶解残基、河泥粉及桑枝发酵液（粉尘、MPR碱解液、尾气冷凝水等）制混合物料；S5.梯度控压制成6~8mm颗粒；S6.MPR酶解残基炭化得腐殖酸，与高岭土制包覆颗粒喷涂烘干。本发明解决纯桑枝成型率低、颗粒松散、热值不足问题，降低灰分、二氧化硫及二氧化碳排放，适配工业供热与民用取暖，实现桑枝高值化。
