An activated carbon manufacturing method may include preparing activated carbon precursors, carbonizing the activated carbon precursors by performing a heat treatment on the activated carbon precursors, equalizing the activated carbon precursors carbonized, in the carbonizing, by grinding the activated carbon precursors, activating the activated carbon precursors by inserting an oxidizing agent and distilled water into the equalized activated carbon precursors and performing a heat treatment on the activated carbon precursors, and introducing metal oxide particles into the activated carbon precursors by mixing the activated precursors, a metal salt, and a reducing agent in a solvent to perform reaction on the activated carbon precursors.

In a feed clean-up process at least two adsorbents (2, 4) are installed in front of an oligomerization reactor (3). Olefin feed is sent over one adsorbent (2) and the nitrile poisons are adsorbed so that clean feed will enter the reactor (3). Before the adsorbent (2) will be saturated, the feed (1) is sent to the other, fresh adsorbent (4). At the same time oligomerization product from the reactor (3) is used to desorb nitriles from the spent adsorbent (2).

A detachable module for optionally recharging sorbent materials, including zirconium phosphate, with an optional bypass and conduits for a sorbent cartridge. The sorbent cartridge can have one or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein recharged.

There is provided an absorbent for decreasing the leakage of halogen compound gases in subsequent processes, at high temperatures and in the presence of high concentrations of water vapor in the process of heating and gasifying a fuel, such as coal, to produce a synthesis gas.

The adsorbent includes a halogen compound absorbent containing 30 to 90% by mass of a basic calcium compound and 10 to 70% by mass of a metal compound other than basic calcium compounds and/or of a clay mineral. A method for producing synthesis gas using the absorbent is also disclosed.

Methods for making a plurality of nanoparticles are provided. The method may include flowing a first component of the core into a reaction chamber; flowing a polymeric material into the reaction chamber; and flowing a second component of the core into the reaction chamber such that the first component reacts with the second component to form a core. The polymeric material forms a polymeric shell around the core.
