A process for converting a first hydrocarbon feed stream to one or more liquid transportation fuels in a petroleum refinery where the feed stream is analyzed by at least one analytical method to produce data that is transformed to wavelet coefficients data. A pattern recognition algorithm is trained to recognize subtle features in the wavelet coefficients data that are associated with an attribute of the feed stream. The trained pattern recognition algorithm then rapidly classifies potential hydrocarbon feed streams as a member of either a first group or a second group where the second group comprises hydrocarbon feed streams where the attribute or chemical characteristic at or above a predetermined threshold value. This classification allows rapid decisions to be made regarding utilization of the feedstock in the refinery that may include altering at least one variable in the operation of the refinery.

In chemical processes for cracking hydrocarbons, reactors are subject to coking During the decoke process carburization of the metal substrate can occur, negatively impacting reactor life. Decokes are also costly due to down-time where costs are incurred without production of commercial products. Reducing the frequency of decokes provides an opportunity to reduce the financial impacts of downtimes. A start-up procedure is described herein that limits initial coke deposition, leading to a reduced tendency for carburization of the metal substrate, improving reactor life, and more importantly, extending reactor run length.

Systems and methods are provided for performing slurry hydroconversion of feeds that include substantial amounts of 1050° F+ (566° C+) components. The productivity of the slurry hydroconversion reaction is improved by recycling slurry hydroconversion pitch or bottoms back to the slurry hydroprocessing reaction system. The mass flow rate of the recycle stream can correspond to 50% or more of the mass flow rate of the fresh feed to the reaction system, and the recycle stream can include more than 50 wt % of 566° C+ components. It has been discovered that using a substantial recycle stream composed of a majority of unconverted 566° C+ bottoms can increase the productivity of the slurry hydroprocessing reaction system when operating at a net conversion relative to 524° C (975° F) of less than 90 wt %. Additionally, by using a recycle stream composed of a majority of 566° C+ components, the amount of lower boiling components (in the heavy hydrocarbon feed and/or in the recycle stream) that are exposed multiple times to the slurry hydroprocessing environment is reduced or minimized This can allow for formation of slurry hydroconversion products with increased amounts of vacuum gas oil boiling range components.
