A process and a composite for removing toxic cations and anions from blood or dialysate is disclosed. The process involves contacting blood or dialysate with a shaped ion exchange composite to remove ammonium and phosphate ions. The composite is a mixture of an anion exchange composition such as zirconia and a microporous cation exchange composition formed into a shaped article and optionally containing a binder such as hydrous zirconium oxide. The microporous cation exchangers are represented by the following empirical formula. or.

A process for removal of trace impurities of hydrides of arsenic, phosphorus, antimony, silicon, and boron and sulfur and oxygenates and compounds containing these impurities from a hydrocarbon stream comprising contacting the hydrocarbon stream with an adsorbent material selected from the group consisting of zeolites and promoted alumina to adsorb compounds containing sulfur and/or oxygenates, contacting the hydrocarbon stream with an adsorbent material comprising one or more active metal oxides to remove the hydrides and contacting the hydrocarbon stream with an adsorbent material that removes water.

Methods are disclosed for the treatment of feedstocks comprising a fatty acid- or triglyceride-containing component to remove contaminants that are detrimental to the conversion of such feedstocks to hydrocarbons, and especially biofuel fractions such as diesel or aviation biofuels. Contaminants contributing to the presence of trace elements in animal fats and/or plant oils, as components of feedstocks, hinder the ability to catalytically convert these feedstocks, for example by hydroprocessing, to biofuels.

Methods and apparatuses for processing a renewable feedstock are provided herein. In an embodiment, a method for processing a renewable feedstock includes deoxygenating a stream of the renewable feedstock at a first pressure to form a stream of paraffins. The pressure of the stream of paraffins is reduced to a second pressure which is at least about 345 kPa less than the first pressure. Further, normal paraffins in the stream of paraffins are converted to form a stream of converted paraffins.

A two stage hydrocracking process is characterized by operation of the second hydrocracking zone at a reduced pressure, which is conducive to cracking the highly paraffinic effluent of the first hydrocracking zone. The process is also characterized by the passage of the partially compressed hydrogen makeup gas stream into the second hydrocracking zone followed by compressing the gas recovered from the second hydrocracking zone effluent to form the makeup gas to the first stage hydrocracking zone. There is no recycle gas stream for the second hydrocracking zone.
