Abstract
Integrated processes for the conversion of hydrocarbons to C2 and C3 unsaturated hydrocarbons include combustion and cracking of hydrocarbons, dry oxidative reforming of methane, and catalytic hydrogenation of acetylene. Reactive products formed among the integrated processes may be distributed and recycled among the processes for the conversion of the hydrocarbon feedstock.
Claims20
A method of producing unsaturated C2 hydrocarbons comprising:
- subjecting a hydrocarbon feedstock to an oxidative pyrolysis process to form at least acetylene, a carbon dioxide product, and a first syngas product;
- hydrogenating the acetylene to form at least ethylene and a hydrogenation product;
- and
- converting at least a portion of the carbon dioxide product through an oxidative dry reforming process to form at least a second syngas product.
A system for converting hydrocarbons to unsaturated C2-C3 hydrocarbons, the system comprising:
- a cracking reactor to effect at least a cracking or a combustion of a hydrocarbon feedstream to form a product mixture comprising at least acetylene, a carbon dioxide product, and a first syngas product;
- a separator configured downstream from the cracking reactor to effect a separation among components of the product mixture;
- wherein acetylene is separated from the product mixture;
- carbon dioxide is separated from the product mixture, or a combination thereof;
- a hydrogenation reactor configured downstream from the separator to effect at least a hydrogenation of the acetylene and a formation of a hydrogenation product;
- and
- a dry reforming reactor configured subsequent to the separator to effect at least conversion of carbon dioxide to a second syngas product.
