Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total global coal production.

Coal: Here natural gas is a gas, petroleum is a liquid, and coal is, of course, a solid. Coal looks like chunks of midnight black rock, which are harvested from the Earth by workers in mining operations. During surface or underground mining, coal can be recovered. For surface mining, the process is straightforward.

Thus Flexicoking is an integrated coking and gasification process for upgrading heavy feedstocks. This process converts these feeds to a 99% yield of fuel gas, naphtha, middle distillates, heavy gas oil, and a lowsulfur coke gas. The remaining 1% is petroleum coke containing metals and other ash components present in the feed.

Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century, coal has yielded its place to petroleum and natural ...

Why is the COP28 conference important? Since the adoption of the Paris Agreement on climate change at COP21 in 2015, subsequent conferences have revolved around implementing its key goal: halt global average temperature rise to well below 2°C and pursue efforts to limit the rise to °C above preindustrial levels. If Paris gave us the agreement, Katowice and Glasgow showed us the plan.
