[Effects of slow release-fertilizers on yield, nutrient contents and quality of Coptis chinensis].

Shijiang Chen Deli Zhang Guoyue Zhong Yingfan Cai

Objective To study the effects of four kind of slow-release fertilizers on yield and quality of Coptis chinensis. Method One to three years C. chinensis was fertilized with slow-release fertilizers twice in April and in September. The yield and nutrient content along with quality of C. chinensis were measured after two years growth. Result and conclusion All of the slow-release fertilizers increased the yield obviously, and the effect of SRF1 and SRF4 is the most significant. Comparing with control group, the N content in aerial part of 1-2 year-old C. chinensis treated with SRF1 and SRF4 was lower and P and K were higher than that of control group, and the N content in aerial part of 3 year-old C. chinensis treated with SRF1 and SRF4 was higher and P and K were higher than that of control group; The N content in the root of land 3 year-old C. chinensis treated with SRF1 and SRF4 showed no significant difference comparing with control group, and P and K were lower than that of control group, the N and P content in root of 2 year-old C. chinensis treated with SRF1 and SRF4 was higher and K were lower than that of control group. After two years growth berberine content of C. chinensis treated with SRF1, SRF2 and SRF3 were significantly increased, and total alkaloid content of C. chinensis treated with SRF1, SRF3 and SRF4 were significantly increased. We recommend that SRF4 is used as the special fertilizer for 1-year-old C. chinensis, and the SRF1 and SRF4 for 2-year-old C. chinensis, and the SRF1 for 3-year-old C. chinensis.

[Effect of Biochar Structure on Adsorption Characteristics of Ammonia Nitrogen].

PubMed (2019)

Mei Chen Fang Wang Deli Zhang Weiming Yi

Ammonia inhibition is a common phenomenon in biogas engineering which is rich in organic nitrogen substrate. Ammonia nitrogen in anaerobic digestate slurry can be fixed by biochar adsorption. Biochar is prepared from corn stalks and rice husks as raw materials at different temperatures (350℃, 450℃, and 550℃). The purpose is to explore the correlation between the physical and chemical structure of biochar and the adsorption characteristics of ammonia nitrogen. The structure and physicochemical properties of biochar were analyzed by elemental analysis, FTIR, BET, etc., and batch adsorption experiments were conducted to investigate the effect of biochar with different physicochemical properties on adsorption characteristics of ammonia nitrogen. The results indicated that the carbon and ash content in biochar increases with an increase in pyrolysis temperature; the NH4+-N adsorption of the corn stalk biochar prepared at 450℃ (CS450) and the rice husk biochar prepared at 550℃ (RH550) follows the quasi-secondary-and quasi-first-order kinetic models. The Freundlich adsorption model can better describe the isothermal adsorption process of ammonia nitrogen in CS450 and RH550 biochar. The adsorption capacity of corn straw carbon correlated strongly with its surface functional groups. The most significant correlation with the adsorption capacity of rice husk carbon is the specific surface area of biochar, followed by surface functional groups, and finally ash content. Among them, RH550 had the best adsorption performance, and the maximum adsorption capacity was 12.16 mg·g-1.

Selective preparation of furfural via the pyrolysis of cellulose catalyzed with nitrided HZSM-5

BioResources (2021)

Xinluan Wang Shanjian Liu Deli Zhang Dongmei Bi Lihong V. Wang

Furfural is a high-value compound that can be prepared by catalytic pyrolysis of biomass. In order to improve the selectivity of furfural in the process of cellulose catalytic pyrolysis, the ammonia-modified HZSM-5 (N-HZSM-5) was used as the catalyst for experimental research on a horizontal fixed bed. The effects of different nitriding temperatures and times on N-HZSM-5, and the effects of different catalyst to cellulose (CA to CL) ratios on furfural selectivity were evaluated. The results showed that N-HZSM-5 can effectively improve the selectivity for furfural. At the optimal conditions (nitriding temperature: 800 °C, nitriding time: 6 h, CA to CL ratio: 4), the selectivity of furfural was up to 24%, which was much higher than those of noncatalytic pyrolysis (1.2%) and HZSM-5 catalytic pyrolysis (3.6%). In order to better evaluate the performance of the catalyst, a series of characterizations were carried out on the N-HZSM-5. The results showed that compared with HZSM-5, N-HZSM-5 had an increased pore size, it was less acidic, and it had more uniform surface acidity. It was conducive to the selective formation of furfural. Therefore, the ammonia-modification can effectively control the structure and acidity of HZSM-5, and N-HZSM-5 exhibits a non-negligible potential in catalyzing the pyrolysis of cellulose for furfural.

Comparison study on pyrolysis characteristics and kinetics of corn stover and its digestate by TG-FTIR

BioResources (2017)

Deli Zhang Fang Wang Weiming Yi Zhihe Li Xiuli Shen

The pyrolysis potential of corn stover digestate (CSD) was compared with corn stover (CS). The effects of anaerobic digestion (AD) on pyrolysis were investigated at different rates by a thermogravimetric analyzer coupled with Fourier transform infrared spectrometry (TG-FTIR). The distributed activation energy model (DAEM) was used to show the differences in the kinetics. The results indicated that the AD process improved the thermal stability with lower mean reactivity (RM), higher solid residue (S850), and decreased release of observed gaseous productions, except for CH4. The release of CH4 from CSD was higher than that of CS, especially in the temperature range of 430 °C to 520 °C. The activation energies (E) of CS and CSD were 184 kJ/mol to 293 kJ/mol (conversions were 0.1 to 0.8) and 99 kJ/mol to 331 kJ/mol (conversions were 0.1 to 0.9), respectively. The activation energies decreased after AD at the same conversion level. The calculated TG data of CS and CSD from the kinetic parameters were in good agreement with the experimental curves.
