This patent of invention is related to a process and a furnace developed for production of charcoal with recovery of gases, tar and pyrolgneous extract. The unity system is composed by a metallic furnace, a loading platform, a carbonization platform and unloading platform. For continuous generation of gases, the process operates with multiple carbonization platforms and one or more furnaces for carbonization platform. The furnace is provided with air inputs in strategic side points and mechanism for relieving pressure. The carbonization system is composed by an exhauster, special pipes for conducting the gases, and devices for the recovery of condensable. The gases generated in the process are directed to a burner, a gasifier or directly in a boiler to generate thermal and/or electrical energy. The technology presents, exclusively, a gravimetric yield in fuel gas superior to 60% and a productivity on charcoal above 800 kg/h, so that each operating cycle of the furnace takes less than 5 hours. The coal is discharged hot, after carbonization and loaded on wooden billets immediately after unloading. The process combines technical, economic, operational, and environmentally viable solutions

A method of retorting oil shale is provided, comprising: continuously feeding oil shale into a retorting unit; heating the retorting unit using renewable electrical energy; converting the oil-shale kerogen into kerogen oil; conveying a cross-flow sweep gas across a moving bed of the oil shale, to carry the kerogen oil out of the retorting unit; recovering the kerogen oil; and recovering spent oil shale. The combination of electrical heating and cross-flow retorting achieves uniform heating to optimize the production of hydrocarbons. A system for retorting oil shale is also provided, comprising: a retorting unit; an inlet for continuously feeding oil shale; electrical-energy elements within the retorting unit; an inlet for conveying a cross-flow sweep gas through the retorting unit; and an outlet for the cross-flow sweep gas carrying the kerogen oil. The principles of the invention may be applied to ex situ systems, in situ systems, or hybrid systems.

The present invention relates to delayed coking of heavy petroleum residue producing petroleum coke and lighter hydrocarbon products. The invented process utilize a pre-cracking reactor and a reactor furnace for mild thermal cracking of the feedstock and an intermediate separator, before being subjected to higher severity thermal cracking treatment in a coker furnace and a coking drums, resulting in reduction in overall coke yield.
