Embodiment Construction

[0014] figure 1 An embodiment of the hydroprocessing method 5 is shown. The coal feed 10 can be sent to the pyrolysis zone 15, the gasification zone 20, or the coal feed 10 can be divided into two parts and sent to the two zones.

[0015] In the pyrolysis zone 15, the coal 10 is heated to a high temperature in the absence of oxygen, for example, up to 2000°C (3600°F), thereby driving out volatile components. Coking produces coke 25 and coal tar stream 30. Coke 25 can be used in other processes, such as for the production of steel.

[0016] If desired, the coal tar stream 30 containing volatile components from the coking process can be sent to the pollution removal zone 35.

[0017] The optional pollutant removal zone 35 for removing one or more pollutants from the coal tar stream or other process stream can be located at various positions in the process, depending on the specific pollutant’s impact on the product or process. The reasons for the impact and removal of contaminants w...

Abstract

A multifunction hydrotreater includes a particulate removal zone having a particulate trap to remove particulate contaminants from a coal tar stream and a demetallizing zone including a demetallizing catalyst to remove organically bound metals from the de-particulated stream. The demetallizing zone is positioned after the particulate removal zone. The hydrotreater also includes a hydrodesulfurization, hydrodenitrogenation, and hydrodeoxygenation zone positioned after the demetallization zone, which includes at least one hydrodesulfurization, hydrodenitrogenation, and hydrodeoxygenation catalyst to provide a hydrotreated coal tar stream.

Description

[0001] Priority statement [0002] This application claims the priority of provisional application No. 61 / 906,083 filed on November 19, 2013, and the contents of which are fully incorporated herein for reference. Background of the invention [0003] Many different types of chemicals are produced from petroleum processing. However, because of increased demand in recent years, oil has become more and more expensive. [0004] Therefore, attempts have been made to provide alternative sources of raw materials for the production of chemicals. Research is now devoted to the preparation of liquid hydrocarbons from solid carbonaceous materials, such as coal, which can be obtained in large quantities in many countries such as the United States and China. [0005] The pyrolysis reaction of coal produces coke and coal tar. The process of preparing coke or "coking" involves heating the material to a very high temperature in a closed container in the absence of oxygen. Coke is a porous but hard ...
