Biomass Physical Property Characterization Service

Trustworthy Physical Properties Analysis in Biomass at Creative Biolabs

Creative Biolabs has an experienced team of biomass analysis experts. We provide a variety of Biomass-related Analysis Services, such as Lignocellulose Composition analysis, physical properties analysis, and Anaerobic Digestion analysis services. Comprehensive physical property analysis of biomass helps to understand the characteristics of biomass and provides data support for its effective use.

• Particle size

We grind the biomass sample, then measure the particle size distribution of the particles with a laser particle size analyzer, and observe the morphological characteristics of the particles with a microscope.

• Density

We provide clients with comprehensive characterization of the basic density and bulk density of biomass. Basic density is an inherent property of biomass and is calculated by measuring the mass and volume of biomass samples after drying. Bulk density refers to the mass of a biomass sample within a given volume, which is affected by the shape and arrangement of particles and is often used to describe the compactness of materials in practical applications. We measure the bulk density of biomass using containers of known volume, which helps clients better understand the density characteristics of biomass samples and guide subsequent processing, transportation, and utilization processes.

• Porosity

The pore structure inside biomass affects its adsorption performance and air permeability. We use nitrogen adsorption to determine the porosity of biomass.

• Moisture

Accurate moisture content is very important for controlling the quality and stability of biomass materials. We use drying and titration methods to determine the moisture content in biomass samples to help clients evaluate the moisture state of biomass materials and guide their application in storage, processing, transportation, etc.

Creative Biolabs is equipped with advanced biomass analysis instruments that meet the testing needs of various types of biomass samples. We are committed to providing clients with comprehensive biomass physical property characterization services. We will win the trust of clients through our robust service quality and professional level. Please contact us if you need to consult our services, we look forward to cooperating with you.

Published data

Lignocellulosic biomass is considered to have broad application potential and plays a key role in the fields of materials, chemistry, and energy. To increase the reactivity of biomass, it is often necessary to grind it into an ultrafine powder to increase its surface area. The authors used three devices: a rotating ball mill (RBM), stirrer ball mill (SBM), and vibrating ball mill (VBM) to explore the effect of mechanical force on the properties of wheat straw and pine bark, two common lignocellulosic materials. They measured the particle size distribution (PSD) of the biomass powder by dry and wet methods using a Malvern laser diffraction particle sizer and analyzed the shape and flowability of the granular powder using a particle characterization system and a powder rheometer. The research results showed that pine bark became more uniformly powdered after ultra-fine grinding. Except for SBM, its PSD curves showed a bimodal distribution in the other two grinding methods. Moreover, the d10, d50, and d90 size values produced by different ball mills were very similar. However, for straw, the span value of the PSD curve increased significantly to 4.8 during ultra-fine grinding, revealing the heterogeneity of straw. After integrating all the characterization data, the authors found that pine bark was easier to grind than wheat straw, but its powder dispersibility and compressibility were poor. In addition, the authors also found that the SBM ball mill could provide complementary friction and impact forces and was considered to be the best choice for the efficient refinement of lignocellulose.
