The incremental yield of hydrocarbons having five or more carbon atoms in a cracked product from a thermal cracking process is increased by contacting or treating the tubes of a thermal cracking furnace with a composition comprising tin and silicon.

Method for improving the yield of heavy hydrocarbons in a thermal cracking process

For a given percentage decomposition, the decomposition temperature of an organosilicon compound is reduced by admixing with the organosilicon compound a decomposition promoting organotin compound. The amount of decomposition promoting organotin compound admixed with the organosilicon compound is sufficient to effectively lower the decomposition temperature of the organosilicon required for a given percentage decomposition.

Method of promoting the decomposition of silicon compounds in a process

A process for the production of ethers from a paraffin feedstock. The process includes a novel arrangement of dehydrogenation, isomerization, hydroisomerization, separation and etherification to provide a novel method for the production of ethers from a paraffin feedstock.

Method for making ether from a paraffin feedstock

A process for the production of ethers and alkylate from a paraffin feedstock. The process includes a novel arrangement of dehydrogenation, isomerization, separation, etherification and alkylation to provide such products.

Method for the production of ether and alkylate from a paraffin feedstock

A novel method for treating the radiant tubes of a fired pyrolysis heater with an antifoulant composition for inhibiting the formation and deposition of coke thereon. Such novel method includes introducing the antifoulant into the crossover conduit between the convection tubes and radiant tubes of the fired pyrolysis heater.

Method for treating the radiant tubes of a fired heater in a thermal

The rate of formation of carbon on the surfaces of thermal cracking tubes and the production of carbon monoxide during thermal cracking of hydrocarbons are inhibited by the use of cracking tubes treated with an antifoulant, including tin compound, silicon compound and sulfur compounds in the presence of a reducing gas such as hydrogen. Additionally, the concentration of carbon monoxide in a pyrolytic cracking process product stream is reduced by the treatment of the thermal cracking tubes of such process with a reducing gas having a concentration of a sulfur compound.
