Abstract: A method for removing ash from a solid carbon material: Reaction conditions are mild, and ash may be removed more effectively. The ash removing method comprises: S1) mixing an alkaline sub-molten salt medium and a solid carbonaceous material to be treated, heating so that alkali and ash in the solid carbonaceous material to be treated react in the alkaline sub-molten salt medium, and performing solid-liquid separation on a mixed slurry resulting from the reaction to obtain a first solid product and an alkali treatment solution, wherein in the alkaline sub-molten salt medium, the mass fraction of the alkali is greater than or equal to 50%; S2) using an acid solution to perform acid cleaning treatment on the first solid product, and performing solid-liquid separation again to obtain a second solid product and an acid cleaning solution.

Abstract: The present disclosure provides a method for obtaining adventitious tetraploid buds of Blumea balsamifera, comprising the following steps: selecting a root segment of diploid B. balsamifera as an explant, culturing the root segment in a chromosome doubling inducing medium supplemented with 0.025-0.1 mg/L 1-naphthaleneacetic acid (NAA), 1.0-2.0 mg/L 6-benzylaminopurine (6-BA), and 90-150 mg/L colchicine, inducing explant cells, and simultaneously doubling chromosomes and differentiating the adventitious buds. The present disclosure fills the blank of using a root of B. balsamifera as the explant and increases effective explant sources during the propagation, proliferation and biotechnological breeding of B. balsamifera. More importantly, root cells of the B.
