The conversion of methylcyclohexane to toluene is a classic aromatization reaction. This platinum (Pt)-catalyzed process is practiced on scale in the production of gasoline from petroleum. [13] It is also one of a host of substances in jet fuel surrogate blends, e.g., for Jet A fuel. [14] [15]
The process, which is catalyzed by platinum supported by aluminium oxide, is exemplified in the conversion methylcyclohexane (a naphthene) into toluene (an aromatic). [2] Dehydrocyclization converts paraffins (acyclic hydrocarbons) into aromatics. [3] A related aromatization process includes dehydroisomerization of methylcyclopentane to benzene:
According to reports for Chiyoda's demonstration plant, which has a production rate of 50 Nm 3 per hour, the dehydrogenation of MCH happens at 350 °C and with a Pt/Al 2 O 3 catalyst, with an MCH conversion rate greater than 95% and toluene selectivity higher than 99.9%. For the (de)hydrogenation of TOL/MCH, several catalysts including Ni, Pt ...
Catalytic reforming is a chemical process used to convert naphthas from crude oil into liquid products called reformates, which are premium "blending stocks" for high-octane gasoline. The process converts low-octane linear hydrocarbons (paraffins) into branched alkanes (isoparaffins) and cyclic naphthenes , which are then partially ...
It has been patented for use in air fresheners. [8]U.S. Patent 4915825 describes a froth flotation process for cleaning coal where a mixture of 95% MCHM, 4% water, and 0.1% 4-methylcyclohexanemethanol monoether (such as 4-(methoxymethyl)cyclohexanemethanol) is used as a frothing agent, and finely divided coal particles adhere to air bubbles induced into the agent which rise to the surface.
The pre-commercial demonstration plant has also achieved 720 hours of continuous operation. [14] Primus Green Energy has announced plans to break ground on its first commercial STG+ plant in the second half of 2014, and the company has announced that this plant is expected to produce approximately 27.8 million gallons of fuel annually.

Therefore, to reduce torsional strain, cyclohexane adopts a three-dimensional structure known as the chair conformation, which rapidly interconvert at room temperature via a process known as a chair flip. During the chair flip, there are three other intermediate conformations that are encountered: the half-chair, which is the most unstable ...
A chemical plant is an industrial process plant that manufactures (or otherwise processes) chemicals, usually on a large scale. [1] The general objective of a chemical plant is to create new material wealth via the chemical or biological transformation and or separation of materials. [2]
