Dimethyl ether (DME) is a greener fuel, which is derived from lowrank coal. Integrating synthetic gas (syngas) as an intermediate and DME production is greener route for lowrank coal processing. Syngas could be fabricated by catalytic gasification over K 2 CO 3 or Ca(OH) 2 exhibited lower energy consumption than conventional gasification. Then, syngas product is transformed to DME via ...

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".

Methanol is a clean fuel and an important feedstock for the petrochemical industry. Conventionally, the coaltomethanol process generates a substantial amount of CO2 emissions with a low yield of methanol. In this study, we propose the conceptual design development of coaltomethanol process using captured CO2 from the gasification plant by implying process intensification. The base case and ...

Methanol is predominantly produced by a coaltomethanol process in China. However, this process is criticized by high CO 2 emissions because of the high carbon contents of coal. The high CO 2 emission and low resource utilization efficiency greatly weaken the competitiveness of the coalto methanol industry.

Traditional, olderstyled pulverized coal power plants operate today with a typical efficiency of 30 to 35 percent, meaning if we start with 100 units of fuel coming into a power plant, we lose about twothirds of its energy content to waste heat, and only get onethird out in the form of electricity.

There are two commercially demonstrated routes for converting coal to transportation fuels through gasification (Figure 1). The widely known Fischer Tropsch process was first discovered in the 1920s. It has been commercially practiced by in several different forms to produce fuels from either coal or natural gas.

Coal liquefaction is the process of converting solid coal into liquid fuel. This process has been developed as a means to utilize coal resources that are otherwise difficult to access and transport. The resulting liquid fuel, called synthetic crude oil, can be refined into a variety of fuels, including diesel, gasoline, and aviation fuel.

Technology has come a long way since the first coalderived liquid fuel (a synthetic crude oil) was produced through direct liquefaction in the early 1900s. In 1925, Franz Fischer and Hans Tropsch used an indirect liquefaction process, which still bears their name, to produce excellent transportation fuels.
