PROCESS FOR HYDROTREATMENT OF MATERIALS FROM RENEWABLE SOURCES
A process for hydroprocessing a renewable feedstock involves introducing the renewable feedstock and hydrogen in a downward flow into a top portion of a fixed-bed reactor and distributing the downward flow to a top surface of a first catalyst bed in a manner such that the top surface is uniformly wetted across the reactor cross section. The feedstock then flows downwardly through the first catalyst bed, where it is reacted under hydroprocessing conditions sufficient to cause a reaction selected from the group consisting of hydrogenation, hydrodeoxygenation, hydrodenitrogenation, hydrodesulphurization, hydrodemetallization, hydrocracking, hydroisomerization, and combinations thereof. A hydrocarbon liquid separated from the reaction effluent is recycled to the renewable feedstock in a ratio of 0.4:1 to 1.8:1, based on the volume of the renewable feedstock.

DURABILITY TEST METHOD AND SYSTEM AND DATA TABLE GENERATION METHOD FOR BATTERY PULSED HEATING
A lithium-ion battery to be tested is put into a temperature chamber at a first temperature value and subjected to pulsed heating until the pulsed heating time reaches the preset pulse duration. The chamber temperature is adjusted to a second value and a capacity degradation value of the battery is obtained, so as to obtain durability of the battery. Before testing of the capacity degradation value of the battery, continuous pulsed heating is conducted. After the battery is heated for a period of time, the temperature elevation and heat dissipation of the battery will reach stable values and the temperature will no longer rise. Such pulsed heating does not require a long period of standing at low temperature. Therefore, a large amount of test time can be saved, the test period shortened, and the influence of battery temperature on battery durability can be verified through a large number of experiments.

The present application relates to a method and system for determining parameters of battery pulsed heating. The reference potential of the anode of the lithium-ion battery is obtained in real time in the positive and negative pulsed heating process under various heating parameters. The relationship between reference potential and threshold potential indicates whether Li plating has occurred to the lithium-ion battery. When the reference potential is smaller than the threshold potential, the first heating parameters are adjusted to avoid Li plating and improve battery life. By recording the heating parameters when the reference potential is greater than the threshold potential, it can be ensured that the pulsed heating parameters have no significant impact on the life of the battery.

METHOD AND SYSTEM FOR REDUCING VESSEL FUEL CONSUMPTION
A method for the reduction of ship fuel consumption through the optimisation of vessel draft, speed and trim using historical vessel data. Historical global, online data, is collected for multiple vessel operating parameters associated with its previous voyages. After initial filtering and cleaning of the gathered data, a process of analysing the data to determine the optimum draft, speed and trim for the vessels' given speed is described. The determined optimum draft, speed and trim values are then presented to the Captain or an automatic draft and trim optimisation system for the current draft and trim to be adjusted. This application therefore discloses a method for analysing historical vessel data to provide advice on optimum draft, trim and speed. A method for predicting the achievable fuel savings and recording the fuel savings achieved is also disclosed.

A method for calibrating a direct flow simulation of a rock sample involves providing a 3D image of a rock sample and generating a segmented structural image of the rock sample from the 3D image by selecting voxels to represent either a pore space or a solid material. Fluid flow is simulated on the segmented structural image with a direct flow simulation. A 3D spatially-resolved fluid velocity map is generated for one or more fluid phases at a pore-scale resolution using pulsed field gradient nuclear magnetic resonance imaging. The simulated fluid flow and the 3D spatially-resolved fluid velocity map are compared to calibrate the direct flow simulation across the rock sample.

A process for hydroprocessing a renewable feedstock involves introducing the renewable feedstock and hydrogen in a downward flow into a top portion of a fixed-bed reactor and distributing the downward flow to a top surface of a first catalyst bed in a manner such that the top surface is uniformly wetted across the reactor cross section. The feedstock then flows downwardly through the first catalyst bed, where it is reacted under hydroprocessing conditions sufficient to cause a reaction selected from the group consisting of hydrogenation, hydrodeoxygenation, hydrodenitrogenation, hydrodesulphurization, hydrodemetallization, hydrocracking, hydroisomerization, and combinations thereof. A hydrocarbon liquid separated from the reaction effluent is recycled to the renewable feedstock in a ratio of 0.4:1 to 1.8:1, based on the volume of the renewable feedstock.
