Abstract: A mapping method and system. The method includes receiving from a computing system, a selection of a first candidate skill from a list of candidate skills. The computing system receives a selection of a first work location of associated with a first skill. The computing system determines a first geographical location identifier identifying a first area comprising the first work location. The computing system determines a first work region comprising the first area and the first work location. The computing system selects a first group of suppliers associated the first work region. The computing system generates a candidate request document comprising the first candidate skill, the first work region, and the first work location. The computing system transmits to the first group of suppliers the candidate request document.

Abstract: A process for the production of alkyl tert alkyl ether, comprising the steps of providing a liquid hydrocarbon feedstock containing diolefin in an amount greater than or equal to about 2% wt, mixing said feedstock with an alcohol selected from the group consisting of methanol, ethanol, propanol and mixtures thereof and with hydrogen so as to provide a mixture of said feedstock, alcohol and hydrogen and contacting said mixture with an etherification catalyst under etherification process conditions including a pressure sufficient to maintain said hydrogen in a liquid phase, and a space velocity (LHSV) of less than or equal to about 1 h.sup.-1 so as to provide said alkyl tert alkyl ether without poisoning said catalyst.

Abstract: A process for the production of an ether-rich additive for gasoline, and more particularly, the production of MTBE, TAME and mixtures thereof from light hydrocarbon streams comprising passing the light hydrocarbon stream, preferably from an FCC feedstock, through a superactivated porous particulate medium so as to remove nitrogen compounds, mercaptan and water prior to contacting the feedstock with a catalyst under etherification process conditions. The present invention further includes a process for regenerating the spent superactivated mediums used for purifying the feedstock employed in the process for the production of ether-rich additives for gasoline.

Abstract: A process for treating alumina mediums used for purifying a hydrocarbon feedstock employed in a process for the production of ether-rich additives for gasoline.

Abstract: A process for the production of an ether-rich additive for gasoline, and more particularly, the production of TAME from light hydrocarbon streams by admixing the light hydrocarbon stream, preferably from an FCC feedstock, prior to distillation of the feedstock with an alcohol in a C.sub.5 feedstock and contacting the feedstock with a catalyst under etherification process conditions.
