| 摘要 |
The present invention generally relates to compositions and methods for scavenging hydrogen sulfide and/or mercaptans from fluids. More particularly, the invention relates to the use of amino acetal and ketal compounds as a hydrogen sulfide or a mercaptan scavenger for hydrocarbon fluids, particularly for natural gas, crude oil, field oil, fuel oil, naphtha, gasoline, kerosene, diesel, refinery gas, coal gas, tar, asphalt, coke gas, ammonia synthesis gas, gas from a sulfurization plant, or industrial gas streams. |

1. A method of reducing the amount of hydrogen sulfide or a mercaptan in a hydrocarbon fluid comprising contacting the hydrocarbon fluid with an effective amount of a scavenger composition comprising a compound of formula 1 having the structure:wherein
R1 is independently —NR3R4, —O(CH2)nNR5R6, or —OR7; R2, R3, R4, R5, and R6 are independently hydrogen, alkyl, alkenyl, or alkynyl; R7 is alkyl, alkenyl, or alkynyl; n is an integer from 1 to 10; and R2 is hydrogen when R1 is —NR3R4. |
