The present disclosure provides compositions and methods that are useful in removing, lowering the amount of, or otherwise controlling hydrogen sulfide and mercaptans. The compositions and methods can be used in any industry where hydrogen sulfide poses problems, such as when dealing with crude oil based, natural gas based, and/or coal based products. The present disclosure provides compositions and methods that can reduce the amount of or eliminate hydrogen sulfide in a variety of mediums.

Disclosed herein are polymers formed by the condensation of bis(hydroxycarbyl)-aminophenolic compounds with aldehydes. The condensation polymers include one or more repeat units having bis(hydroxycarbyl)amino functionality. The hydroxyl groups of the bis(hydroxycarbyl)amino functionalities are available for further condensation with an epoxide, such as ethylene oxide, to yield a polyalkoxylated polymer. The polymers are useful as antipolymerants, polymerization retardants, surfactants, or a combination of these in one or more industrial systems.

A method to make a phosphorus modified zeolite can include providing a zeolite including at least one ten member ring in the structure, steaming the zeolite, mixing the zeolite with one or more binders and shaping additives, and then shaping the mixture. The method can include making a ion-exchange. The shaped mixture can be steamed. Phosphorous can be introduced on the catalyst to introduce at least 0.1 wt % of phosphorus, such as be dry impregnation or chemical vapor deposition. A metal, such as calcium, can be introduced. The catalyst can be washed, calcinated, and then steamed. The steaming severity (X) can be at least about 2. The catalyst can be steamed at a temperature above 625 C., such as a temperature ranging from 700 to 800 C. The catalyst can be used in alcohol dehydration, olefin cracking, MTO processes, and alkylation of aromatics by alcohols with olefins and/or alcohols.
