A method of producing fuel that includes providing a feed comprising natural gas, a portion of which is renewable natural gas, to a steam methane reformer in a hydrogen production unit. The feed includes a first portion that is converted to syngas and a second portion that passes through the steam methane reformer unconverted. The unconverted feed is directed to one or more burners of the steam methane reformer as fuel. The renewable natural gas is apportioned such that the first portion of the feed, which is feedstock, has a larger renewable fraction than the second portion, which is fuel. Apportioning a higher renewable fraction to the portion of the feed that is converted increases the yield of renewable content.

Provided is a method for upgrading polymer waste-based material. The method includes providing a polymer waste-based feedstock, providing a crude oil-derived feedstock, mixing the polymer waste-based feedstock, the crude oil-derived feedstock, and optionally a further feed material, to provide a feed mixture, hydrotreating the feed mixture in a FCC feed hydrotreater to provide a hydrocarbonaceous material, and recovering at least a distillate product and a distillation bottoms product from the hydrocarbonaceous material (step E).

A process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; sequentially removing ammoniacal, sulphurous and carbon dioxide impurities from the raw synthesis gas to form desulphurised gas and recovering carbon dioxide in substantially pure form; converting at least a portion of the desulphurised synthesis gas to a useful product. Despite having selected a more energy intensive sub-process i.e. physical absorption for removal of acid gas impurities, the overall power requirement of the facility is lower on account of lower steam requirements and thereby leading to a decrease in the carbon intensity score for the facility.

A method for pyrolysing plastic material. The method comprises the steps of: heating and densifying plastic material; transporting the plastic material to one or more reactors; and pyrolysing the plastic material in the one or more reactors. The plastic material is maintained in a heated state during the transporting step. A system for pyrolysing plastic material is also provided.

Provided is a method for upgrading a bio-based material, the method including the steps of pre-treating bio-renewable oil(s) and/or fat(s) to provide a bio-based fresh feed material, hydrotreating the bio-based fresh feed material, followed by separation, to provide a bio-propane composition.

The present invention relates to debottleneck solution for delayed Coker unit. More particularly, this invention relates to bottoms of vacuum residuum routed to Coker unit through de-asphalting unit to avoid revamp of existing Coker for the processing of heavier feed stock when there is a change in crude slate. Another object of the invention, in particular, relates to improved delayed coking products, a process used in petroleum refineries to crack petroleum residue, thus converting it into gaseous and liquid product streams and leaving behind solid, carbonaceous petroleum coke.

A process for producing fuel-range organic oxygen-containing compounds is provided. The process includes converting glycerol in the presence of a metal oxide catalyst. The fuel-range organic oxygen-containing compounds can be deoxygenated to produce gasoline and jet fuels or fuel blending components.
