Humic acid biofertilizer production method
Humic acid is a kind of natural macromolecule organic acid compound widely existing in nature. It is abundant in soil, peat, lignite, weathered coal and water. It is formed by the biological and chemical effects of animal and plant residues over a long period of time. Humic acid biofertilizer can improve soil environment and fertility. Here is a production method of humic acid biofertilizer.

Efficient Oxidative Depolymerization of Xilinguole Lignite to Produce
Abstract At present, non-fuel utilization as alternative chemical feedstocks becomes very important and significant for the efficient conversion of lignite. To reduce CO2 production, an oxy-cracking technique in weak alkaline aqueous was conducted to selectively depolymerize Xilinguole lignite (XL) into humic acid (HA) under mild condition in this paper. The results indicated that XL has high
