Embodiments disclosed herein provide hydrocarbon additives and methods of making and using the same. The additives are suitable for use in conjunction with gasifiers, furnaces, or other high-temperature vessels. The additives may be part of an input stream to a reaction vessel of a hydrocarbon gasifier. The additives may include materials that at least partially reduce the infiltration of slag into the refractory material.

1. A process for operating a gasifier comprising: providing a feed material in an input stream to a gasifier, wherein the feed material comprises a hydrocarbon and an additive, wherein the additive is a manganese oxide and wherein the feed material is capable of forming a liquid slag protective layer comprising at least 15% by weight of manganese oxide; andoperating the gasifier at a temperature higher than the melting temperature of the liquid slag such that the feed material forms the liquid slag, wherein the feed material comprises petroleum, coke, or biomass. 2. The process of claim 1, wherein the additive is added to the input stream as a powder or a slurry. 3. The process of claim 1, wherein the hydrocarbon and the additive are added to the input stream simultaneously. 4. The process of claim 1, wherein the additive is added to the input stream continuously during the operation of the gasifier. 5. The process of claim 1, wherein the additive is added to the input stream intermittently during the operation of the gasifier. 6. The process of claim 1, wherein the gasifier is operated at a temperature of at least 1500° C.
