Disclosed is a method for making dimethyl ether by reactive distillation. The method provides a reactive distillation tower with a top, a bottom, and rectification, reaction and stripping zones defined therein. The top of the reactive distillation tower is retained at 25&#xb0; C. to 40&#xb0; C. while the bottom of the reactive distillation tower is retained at 84.6&#xb0; C. to 170&#xb0; C. Each of the rectification, reaction and stripping zones includes several sieving trays. The reaction zone of the reactive distillation tower is filled with catalyst. The pressure in the reactive distillation tower is lower than 8.0 bars. Methanol is introduced into the reactive distillation tower so that the methanol travels from the reaction zone toward the bottom for contact with the catalyst to provide a top stream and a bottom stream. The top stream includes dimethyl ether. The bottom stream includes water and a remaining portion of the methanol. Finally, the dimethyl ether is collected in the top of the reactive distillation tower. The purity of the collected dimethyl ether is higher than 99%.

A fast heat transfer device is provided. The device dissipates heat and generates power at the same time. A liquid flow is used to absorb heat for forming a vapor gas flow; then, the gas flow drives a blade turbine and a power generator; and, finally, the gas flow is cooled down to become the original liquid flow for recycling. Thus, the present invention dissipates heat and generates power simultaneously with a minimized size and a reduced cost together with energy conservation.

Disclosed is a method for making a refractory material from aluminum residues of aluminum recycling. At first, the aluminum residues is mixed with adhesive solution so that the percentage by weight of the adhesive solution is 5 wt % to 10 wt %. The mixture is granulated into grains. The grains are filled in a mold, pressed and then removed from the mold so that the grains are turned into a green body. The green body is heated in a furnace at a range of temperature from 1100&#xb0; C. to 1400&#xb0; C. so that the grains are sintered and become a refractory material.

Disclosed is a method for increasing the yield of a slurry bed reactor. The method provides a slurry bed reactor with a recycling unit or a replacing unit. An absorbing agent is fed into the slurry bed reactor. The absorbing agent is a substance that can react with at least one product of a primary reaction or at least one reactant of a side reaction. Then, the absorbing agent is transmitted into the recycling unit or the replacing unit. The recycling unit renews the absorbing agent and sends the renewed absorbing agent back into the slurry bed reactor for reuse. The replacing unit replaces the absorbing agent with new absorbing agent and sends the new absorbing agent into the slurry bed reactor for use.

Slag fiber is used to fabricate a friction material. Friction factor and abrasion loss of the friction material are controlled. The friction material can be used to make linings. Thus, slag fiber can be used as a replacement for natural material to make a friction material, and waste is thus recycled.
