Processes

The utilization of biomass waste as a raw material for renewable energy is a global concern. Pyrolysis is one of the thermal treatments for biomass wastes that results in the production of liquid, solid and gaseous products. Unfortunately, the complex structure of the biomass materials matrix needs elevated heating to convert these materials into useful products. Microwave heating is a

A review on the microwave

2013/12/1A quartz reactor was placed into a 2.45 GHz, 1000 W constant input power microwave oven and He was used as the carrier gas in the experiments. The results were compared with those from conventional pyrolysis methods and it was found that microwave pyrolysis required a much shorter time in comparison with an electrical furnace.

Microwaving coal produces surprising results

Scientists have discovered that exposing ordinary coal powder to electromagnetic radiation can turn it into a valuable crystalline conductor. The University of Wyoming recently discovered heating up pulverized coal powder with copper foil in a conventional microwave oven can produce nano-graphite

Coal to graphite via microwave heating

2021/1/8Source: Researchers turn coal powder into graphite in microwave oven By cutting the copper foil into a fork shape, the sparks were induced by the microwave radiation, generating an extremely high temperature of more than 1,800 degrees Fahrenheit within a few seconds, says Masi, lead author of the paper.

Here's How It's Possible to Make Perfect Diamonds in a

The process works by placing a tiny fragment of diamond (called a carbon seed) into a microwave along with varying amounts of a carbon-heavy gas - methane is most commonly used. The gas mixture is heated to very high temperatures in the microwave to produce a plasma ball, and inside this, the gas breaks down and the carbon atoms crystallise and accumulate on the diamond seed, causing it to grow.

Microwave synthesis 'zaps' graphene to perfection

Posted: Jan 22, 2016 Microwave synthesis 'zaps' graphene to perfection (Nanowerk News) By employing microwave radiation and a special ionic liquid solvent, RIKEN researchers have developed a quick, efficient and potentially scalable way to produce large quantities of single-layer graphene (Nature Chemistry, Ultrahigh-throughput exfoliation of graphite into pristine 'single-layer' graphene

Microwave synthesis 'zaps' graphene to perfection

When they mixed the oligomeric ionic liquid with graphite powder and heated the solution for 30 minutes in a microwave oven, the results were impressive—exfoliation occurred with a yield of 93 per cent and practically all of the graphene produced was in the form
