Abstract:
A process for producing triptane and/or triptene from methanol and/or one or more derivatives thereof, and optionally one or more further alcohols and/or derivatives thereof at a temperature in the range of from 150 to 400°C, in the presence of a zeolite catalyst having Brønsted acidity, in which all the carbon atoms in the triptane and/or triptene are derived from the methanol and/or one or more derivatives thereof and the optional further alcohols and/or derivatives thereof, the zeolite catalyst being selected from: i. zeolites having frameworks comprising silicon and aluminium atoms at a Si:Al mole ratio of greater than 2, which zeolites also have a channel structure comprising a ring size of 12 or more non-oxygen atoms in 2 or 3 dimensions; and ii. zeolites having frameworks comprising silicon and aluminium atoms, and which have a framework ring comprising 12 or more non-oxygen-atoms accessible on the external surface of the zeolite and a pore structure in which all of the channels have a ring-size of less than 12 non-oxygen atoms. There is also described a process for producing triptane and/or triptene wherein the zeolite catalyst is zeolite X, the reaction composition additionally comprises a C 3 alcohol and/or one or more derivatives thereof, in which the mole ratio of C 3 alcohol : methanol present in the reaction composition, or derivable from the one or more derivatives thereof present in the reaction composition, is greater than 0.23 : 10, and the temperature of the process is in the range of greater than 200° to 400°C.
Abstract:
A process for converting a mixture of hydrogen and carbon monoxide to a hydrocarbon composition comprising one or more optionally oxygenated hydrocarbons, the process comprising the following steps: (a) providing a first catalyst material comprising cobalt (e.g., in the form of oxide) disposed on a support; (b) contacting the first catalyst material with a first reducing agent at a first temperature (T1) and a first pressure (P1) to form a reduced catalyst material; (c) contacting the reduced catalyst material with carbon monoxide at a second pressure (P2) and a second temperature (T2) to provide a passivated catalyst material, wherein P2 is at least 5 bara, and T2 is at most 250 °C; (d) contacting the passivated catalyst material with a second reducing agent at a third temperature (T3) and a third pressure (P3) to form an activated catalyst material, P2 is greater than or equal to P3, and wherein T3 is at least 300 °C; and (e) contacting the activated catalyst material with a mixture of hydrogen and carbon monoxide.
Abstract:
The present disclosure relates generally to processes for performing an integrated Fischer-Tropsch synthesis of hydrocarbons using methanol. In particular, the disclosure relates to a process comprising: providing a first feed stream comprising H 2 and CO 2 ; contacting the first feed stream with a hydrogenation catalyst for form a first product stream comprising methanol; providing a second feed stream comprising at least a portion of the methanol of the first product stream; contacting the second feed stream with a methanol decomposition catalyst to form a second product stream comprising CO and H 2 ; providing a third feed stream comprising H 2 and at least a portion of the CO of the second product stream; contacting the third feed stream with an iron-containing Fischer-Tropsch catalyst to provide a third product stream comprising C 5+ hydrocarbons and CO 2 .
