Abstract
A method to produce a halogen-depleted gas. The method provides a gas derived from and/or including a source of biogas, mixing the gas with a source of hydrogen to produce a processed gas mixture including an acid, and separating the acid from the processed gas mixture. Sulfur, oxygen, carbon dioxide removal processes are integrated into the method. Production of secondary products, and removal thereof, are included. Pre and post processing may be integrated. Also, production of products from the processed gas.
Claims25
A method to produce a processed gas, comprising:
- (d) subjecting the heated gas to a reaction process to produce a processed gas comprising at least one acid and/or at least one secondary compound by performing one or more operations selected from the group consisting of:
- (i) reducing an amount of oxygen within the gas;
- (ii) converting the halogen-containing species into the at least one acid and/or the at least one secondary compound;
- and
- (iii) controlling a reaction temperature to influence formation and/or formation suppression of at least one acid and/or the at least one secondary compound;
- and
- (e) contacting the processed gas with a material to separate at least a portion of at least one acid and/or the at least one secondary compound.
