The BC sample was mixed with water (at a ratio of 1:1) and then modified in an oven (FO-19070, Across International) at 300 °C for 5 h. These modification temperatures were selected because our previous work showed that 200 °C and 300 °C were optimal modification temperatures in terms of increasing NH 3 /NH 4 + capture for lignite ( Han et ...

Achieving the desired particles via ball mill is a research project. The project depends on the material, grinding time, speed, and combination of grinding jar and quantity/size of milling ball. It is your responsibility to find the best milling procedure based on your material. Across International offers paid sample testing prior purchase.

Biorefinery and Bioethanol Production. Fossil resources are still primary energy and chemical sources; around 75% is used for heat and energy production, about 20% as fuel, and just a few percent for the production of chemicals and materials ().Natural regeneration of fossil resources through the carbon cycle is significantly slower than their current rate of exploitation.

A planetary ball milling was applied as a pretreatment of chitin powder to prepare precursors for chitin nanofiber (ChNF) production. The study aims to examine the effects of ball milling conditions (dry milling, and wet milling in neutral and acidic aqueous medium) on the degree of pre-fibrillation of the ChNF precursors and the characteristics of the resulting …

Ball milling as a mech. dispersion technique has proved its potential. In this work, we use ball milling to disperse up to 5 wt. % CNT in an Al matrix. The effect of CNT content on the mech. properties of the composites was investigated. Cold compaction and hot extrusion were used to consolidate the ball-milled Al-CNT mixts.
