    Abstract: Methods are provided herein for co-processing of biocomponent feeds as well processing of mineral feeds in a reaction system at hydrogen partial pressures of about 500 psig (3.4 MPag) or less. The methods include using stacked beds of both CoMo and NiMo catalysts. The stacked catalyst beds provided unexpectedly high catalyst activity as the input feed to a reaction system was switched between a mineral feed and a feed containing both mineral and biocomponent portions. Additionally, use of stacked catalyst beds can allow for maintenance of the activity for the catalyst system in a reaction system while still achieving a desired activity for both types of feeds.

    Abstract translation: 本文提供了用于共生处理生物组分进料的方法以及在约500psig（3.4Mag）或更低的氢分压下在反应体系中处理矿物进料。 这些方法包括使用CoMo和NiMo催化剂的堆叠床。 堆叠的催化剂床提供意想不到的高催化剂活性，因为反应体系的输入进料在矿物进料和含有矿物和生物组分部分的进料之间切换。 此外，使用堆叠的催化剂床可以维持反应体系中的催化剂体系的活性，同时仍然实现两种类型的进料所需的活性。

    Abstract: This invention relates to methods and apparatus for harvesting by-product oxygen from algae ponds or bioreactors (collectively, "algal biofuel production") for use in an oxygen-requiring process that requires oxygen as a reactant such as syngas, hydrogen, or power production processes, which optionally can be integrated with the algal biofuel production. In some embodiments, the invention provides methods that include a method comprising: collecting oxygen from an algal biofuel production process; and using the collected oxygen in an oxygen- requiring process that requires oxygen as a reactant. In some embodiments, the invention provides systems that include an integrated system comprising: an algal bioreactor that produces biodiesel and oxygen, a pipeline for transporting oxygen to an oxygen-requiring process unit so that the oxygen can be used as reactant in the oxygen-requiring process unit, and the oxygen-requiring process unit.

    Abstract: The invention relates to a method for forming an at least partially renewable diesel product, comprising: hydrodeoxygenating a feedstock comprising about 0.1 wt% to about 50 wt% of a fresh biocomponent portion with a relatively pure hydrogen treat gas in the presence of a hydrodeoxygenation catalyst under relatively low total pressure to form a hydrodeoxygenated product; and separating the hydrodeoxygenated product into a vapor effluent and a liquid effluent, at least a first portion of the latter being recycled to the hydrodeoxygenation step, and at least a second portion of the latter being a diesel product. Advantageously, the hydrodeoxygenation catalyst can have a relatively low catalytic activity (about 50% or less of fresh HDS/HDN activity).
