摘要： An apparatus for purifying impure hydrogen fuel is described that includes a first chamber and a second chamber. The first chamber is configured to receive impure hydrogen fuel in the form of a first mixture of gases with hydrogen gas and carbon monoxide at the first concentration while the second chamber is configured to receive a second mixture of gases with hydrogen gas at the second concentration. The apparatus also includes a solid-state electrolyte that separates the first chamber and the second chamber and includes an adsorbing catalyst. The apparatus also includes a pair of electrodes installed each in the first chamber and the second chamber to create a potential difference is created across the solid-state electrolyte.

摘要： The present invention relates to a process for converting the waste plastic along with the petroleum residue feedstock in a Delayed Coker unit employed in refineries. The invented process aims to convert any type of waste plastic including polystyrene, polypropylene, polyethylene etc. including metal additized multilayer plastics along with the petroleum residue material from crude oil refining such as reduced crude oil, vacuum residue etc. Value added light distillate products like motor spirit, LPG, middle distillates etc. are produced upon co-conversion in the invented process and is recovered and treated along with the products of thermal cracking of hydrocarbon residues. The residual metals in the metal additized plastics upon co-conversion in the invented process will be deposited in the solid petroleum coke.
