Abstract: Scale-up evaluation methods for algal biomass cultivation are provided, and more particularly, simultaneous scale-up evaluation methods for outdoor algal biomass cultivation are provided. The methods control various process variables to isolate the impact of scaling algal biomass cultivation, thereby permitting enhanced scale-up operation design to optimize the quality and quantity of algal biomass.

Abstract: A method for producing diesel fuel from biocomponent feeds includes hydrotreating the feed followed by catalytic dewaxing with a 1-D, 10 member ring molecular sieve containing catalyst. The hydrotreated feed may be cascaded directly to the dewaxing step, or the hydrotreated feed can undergo intermediate separation. The diesel fuel resulting from processing of the biocomponent feed exhibits superior cetane values.

Abstract: Systems and methods are provided for co-processing of biomass oil with mineral coker feeds in a coking environment. The coking can correspond to any convenient type of coking, such as delayed coking or fluidized coking. The biomass oil can correspond to biomass oil with a molar ratio of oxygen to carbon of 0.24 or less on a dry basis. Such types of biomass oil can be formed from pyrolysis methods such as hydrothermal pyrolysis, and are in contrast to biomass oils formed from pyrolysis methods such as fast pyrolysis. By using a biomass oil with a molar ratio of oxygen to carbon of 0.24 or less, improved yields of light coker gas oil can be achieved in conjunction with a reduction in the yield of heavy coker gas oil.

Abstract: Methods are provided for dewaxing a distillate fuel boiling range feed to improve one or more cold flow properties of the distillate fuel feed, such as cloud point, with reduced consumption of hydrogen during the dewaxing process. The reduced hydrogen consumption is achieved by using a dewaxing catalyst with a reduced content of hydrogenation metals, such as a content of Pt or Pd of from about 0.03 wt % to about 0.35 wt %. A distillate fuel feed can be dewaxed to achieve a desired cloud point differential using a reduced metals content dewaxing catalyst under the same or similar conditions to those required for a dewaxing catalyst with higher metals content.

Abstract: Methods are provided for dewaxing a distillate fuel boiling range feed to improve one or more cold flow properties of the distillate fuel feed, such as cloud point, where the distillate fuel feed is fractionated to produce both a jet fuel product and an arctic diesel fuel product. The decrease of cloud point is achieved by using a feedstock having a concentration of nitrogen of less than about 50 wppm and a concentration of sulfur of less than about 15 wppm. Further, the dewaxing catalyst may have a reduced content of hydrogenation metals, such as a content of Pt or Pd of from about 0.05 wt % to about 0.35 wt %. A distillate fuel feed can be dewaxed to achieve a desired cloud point differential using a reduced metals content dewaxing catalyst under the same or similar conditions to those required for a dewaxing catalyst with higher metals content.

Abstract: The present disclosure relates to processes for producing biofuel compositions by processing hydrocarbon co-feed and a bio-oil obtained via hydrothermal liquifaction (HTL) of a cellulosic biomass to form an HTL oil. The cellulosic mass can be processed at an operating temperature of about 425° C. or less and an operating pressure of about 200 atm or less. The HTL oil is co-processed with a hydrocarbon co-feed (e.g., petroleum fraction) in a cracking unit, such as an FCC unit, a coker unit or a visbreaking unit, in the presence of a catalyst to produce a cracked product (biofuel). The bio content of the cracked product provides RIN credits for the cracked product.
