Patent number: 10059632Abstract: A humic acid composition includes fulvic acid, ulmic acid and black humic acid. Fulvic acid is in an amount ranging from 64% to 98 wt % based on a sum weight of fulvic acid, ulmic acid and black humic acid. The content of phenol hydroxyl groups is in a range from 0.76 mmol/g to 2.42 mmol/g in the humic acid composition. The humic acid composition contains a high content of fulvic acid with small molecular weight and a high content of active functional groups, and a high content of phenolic hydroxyl in the active groups. The humic acid composition can provide microbial organic source for soil directly, and improve the nutrient of crops and the soil environment in rhizosphere to promote the breeding of microorganism and delay the attenuation rate of soil microbes.Type: GrantFiled: October 21, 2016Date of Patent: August 28, 2018Assignee: SHANDONG TRALIN PAPER CO., LTD.Inventors: Hongfa Li, Mingxin Song, Liangjin Guo, Yanjin Bi

Patent number: 8778135Abstract: A circular utilization method in pulping and papermaking processes with straw Primary pulp is obtained by digesting straw raw material according to the ammonium sulfite method. Concentrated black liquor is extruded from the primary pulp; paper pulp and diluted black liquor. The concentrated black liquor and the diluted black liquor are mixed, and a contaminated condensate is obtained. A residual concentrate or the concentrated black liquor is used for preparing a fertilizer. The contaminated condensate is mixed with one or more of the waste material obtained from stock preparation, a crop byproduct or organic waste, and substrate or fertilizer is obtained by fermenting the nitrogen source of the contaminated condensate or ammonium sulfite, or using the contaminated condensate for desulfurizing flue gas. Ammonia and flue gas are reacted to obtain the ammonium sulfite as a digestion agent; and water from recycling is used in corresponding phases of the pulping process.Type: GrantFiled: March 11, 2011Date of Patent: July 15, 2014Assignee: Shandong Tralin Paper Co., Ltd.Inventors: Hongfa Li, Mingxin Song, Songtao Chen, Jihui Yang, Liangjin Guo

Patent number: 8771465Abstract: A raw paper prepared by a mixed pulp including straw pulp, which can be used to prepare textbooks, writing papers and office paper with good performance, and the producing method of said raw paper are provided. The weight proportion of the straw pulp in the mixed stock is from 10% to 100%, and the straw pulp has a hardness of KMnO4 value 10-17, an average fiber length of 0.1-2.5 mm, a tensile index of 23-57 Nm/g, a tearing index of 3.0-6.0 mN·m2/g, a folding endurance index of 2-6 kPa·m2/g and a whiteness of 28-50%. Either, the L value of the hue of said raw paper is 65-95, a value is 0-5, and b value is 0-40. The KMnO4 value of hardness of the pulp after oxygen delignification is 10-14. The method includes: adding grass-series raw material into a digester, then adding cooking liquor, heating the cooking liquor to 100-200°, pressurizing to 0.3-0.9 MPa, cooking for 150-250 min, extruding the pulp, washing and obtaining the straw pulp.Type: GrantFiled: December 9, 2009Date of Patent: July 8, 2014Assignee: Shandong Fuyin Paper & Environmental Protection Technology Co., LtdInventors: Hongfa Li, Mingxin Song, Jianmin Wang, Yanjin Bi, Jinxiang Xu, Zhongcheng He
