材料科学是一种材料科学.

背景情况:

棕核 (PKS) 和空果束 (EFB) 是丰富但未充分利用的生物质资源.
原始PKS和EFB具有诸如不均的大小和易腐烂等局限性,阻碍其作为固体生物燃料的使用.
托雷法克和联合颗粒化是提高生物质燃料性能的既定方法.

研究的目的:

为了研究烤温度和PKS/EFB混合比对联合颗粒的特征的影响.
确定从PKS和EFB生产高质量的生物燃料颗粒的最佳条件.

主要方法:

在210°C,240°C和270°C的温度下,PKS和EFB被烧烤30分钟.
在PKS:EFB比率为0:100,25:75,50:50,75:25和100:0的条件下,使用10%的碳甲基纤维素粘合剂共同颗粒化.
分析了颗粒的特性,包括更高的加热值 (HHV),抗拉强度,灰含量和密度变化.

主要成果:

较高的烧烤温度 (高达270°C) 增加了HHV,但降低了机械强度.
由75:25的PKS:EFB混合物制成的颗粒,在240°C下烧烤,显示出最好的整体质量.
这种最佳颗粒的HHV为17.94 MJ/kg,拉力强度为3.5 MPa,灰含量为3.97 wt%,密度变化为0.66%,符合商业标准.

结论:

Production of Biopesticides

Production of Biopesticides

Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...

Biofuels

The microbial conversion of organic matter into biofuels holds potential as a renewable energy source. Among biofuel sources, microalgae are recognized as a highly efficient and adaptable feedstock for biodiesel production, owing to their rapid biomass accumulation, elevated lipid productivity, and capacity to proliferate in diverse aquatic systems, including freshwater, marine, and wastewater habitats. Unlike terrestrial crops, microalgae do not compete for land and can achieve significantly...
