Abstract: This application relates to renewable diesel production and to production of renewable naphtha in a renewable diesel unit. Disclosed herein is an example of a method of renewable diesel production. Examples embodiments of the method may include hydrotreating the biofeedstock by reaction with hydrogen to form a hydrotreated biofeedstock; contacting at least a portion of the hydrotreated biofeedstock with a dewaxing catalyst to produce a renewable diesel product and a renewable naphtha product; separating the renewable diesel product and the renewable naphtha product in a product splitter; and monitoring an octane number of the renewable naphtha product with an analyzer.

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: The present disclosure provides processes for refining hydrocarbon feedstocks and apparatus thereof. In at least one embodiment, a process includes hydroprocessing a mineral hydrocarbon feedstock in the presence of a first catalyst in a first reactor, and removing a first reactor effluent from the first reactor. The process includes hydroprocessing a biocomponent feedstock in the presence of a second catalyst in a second reactor, and removing a second reactor effluent from the second reactor. The process includes mixing the first reactor effluent and the second reactor effluent to form a mixture. The process includes introducing the mixture to a separation unit to form a fuel product. In at least one embodiment, an apparatus includes a first hydroprocess reactor. The apparatus includes a second hydroprocess reactor coupled with the first hydroprocess reactor. The apparatus includes a separation unit coupled with the second hydroprocess reactor.
