Smoked Beef Short Ribs

 · Start your charcoal. Heat up the coals until they are heated through and glowing red and white. Then add more coals and the wood the wood chips of choice to the smoker (or prep your pellet smoker as normal to get to this temperature) This process for us takes typically about 4560 minutes.

Process of Chemical Looping Combustion of Coal

In order to carry out the CLC process in commercial scale reactors and avoid highpressure drops inside, particles should be pelletized to bigger sizes. Particle pelletization was performed using a bench scale table press machine. A maximum force of 600 lb was applied to each pellet. Pellets of different sizes were prepared ranging from 1 to 5 mm.

Effect of the Preoxidation of Coals in the Preparation of ...

 · Activated carbon pellets have been prepared by extrusion of a mixture of oxidized coal and KOH, followed by a carbonization process. Three coals with several ranks (semianthracite, subbituminous, and lignite) have been selected as carbon precursors and oxidized with different treatments (HNO3, H2O2, and air treatment). The coal rank, oxidation conditions, and coal/KOH ratio are .
