The method may utilize treated coal wash residual product and teaches a process for treating coal wash residual product.

The present invention relates to a method for producing agglomerates from a feedstock comprising at least one biomass stream, the method comprising the steps of: combining the feedstock with one or more binding reagents; and introducing the feedstock into an agglomeration apparatus in the presence of a polymerisation activator to produce the agglomerates.

A process for converting C2-5 alkanes to higher value C5-24 hydrocarbon fuels and blendstocks. The C2-5 alkanes are converted to olefins by thermal olefination, without the use of a dehydrogenation catalyst and without the use of steam. The product olefins are fed to an oligomerization reactor containing a zeolite catalyst to crack, oligomerize and cyclize the olefins to the fuel products which are then recovered. Optionally, hydrogen and methane are removed from the product olefin stream prior to oligomerization. Further optionally, C2-5 alkanes are removed from the product olefin stream prior to oligomerization.

The present invention relates to a method for the catalytic conversion in vapor phase of disulfide oil into methane and hydrogen sulfide, comprising the step of contacting disulfide oil, eventually in the presence of water, with a supported transition metal catalyst.

Methods for making higher-octane fuel components from a feed stream of C8+ paraffins, including catalytically cracking the C8+ paraffins using a Zeolite catalyst to produce a reaction product of mid-chain paraffins and olefins and short-chain paraffins and olefins. The reaction product comprises liquid phase paraffins having an increased Octane Value over the feed stream paraffins. The reaction product further comprises a gas phase of short-chain paraffins which are separated from the liquid phase. In embodiments, the short chain olefins are hydrogenated to form mid-chain paraffins and a gas phase containing short-chain paraffins.

Processes for stabilizing toluenediamine residues are disclosed. These processes include adding a low viscosity, low boiling liquid to a toluenediamine residue composition to form a blend, and optionally, continuously monitoring the viscosity of the blend during addition of the low viscosity, low boiling liquid. The low viscosity, low boiling liquid may be added at 5% to 30% by weight based on the total weight of the blend. Further, the low viscosity, low boiling liquid may be added so that the blend has a viscosity of 10,000 cP or less throughout the temperature range of 40° C. to 95° C. Blends of toluenediamine residue compositions and low viscosity, low boiling liquids such as water, and methods of their use as a fuel are also disclosed.

Organic sulfur compounds which are generally present in the crude oil undergoes various transformations while processing the crude oil in the secondary processing units such as fluid catalytic cracker, hydrocracker, delayed coker, visbreaker, etc. The sulfur present in the feed which enters into these secondary processing units are distributed into various products coming out of the units. Sulfur compounds which are present in the various product fractions are removed to meet the desired specifications before routing to the final product pool. Conventionally, sulfur present in the LPG has been removed by amine treatment followed by caustic and water wash. The present invention relates to a process for removal of sulfur and other impurities from Liquefied Petroleum Gas (LPG) comprising olefins through reactive desulfurization route. The present invention is an eco-friendly process as it minimizes or eliminates the use of caustic which is conventionally used to remove the sulfur from LPG.

A process is provided for commissioning a particulate filter for the exhaust system of a device powered in whole or in part by an internal combustion engine. The process improves the filtration efficiency of an uncarbonized or decarbonized particulate filter through a single deposition of metal oxide particles via a gas stream.

A method for preparing biochar, including steps as follows: dosing: putting pre-crushed biomass into a reactor; charring conversion: heating the reactor to a certain temperature and pressure, and putting an active group-containing active agent containing 1% to 5% by mass of biomass and a catalyst containing 1% to 10% by mass of biomass (or putting the catalyst first and then putting the active agent) into the reactor to perform solid solution charring on the biomass; and cooling: after the charring conversion is completed, cooling the reactor to 40° C. or lower to obtain the biochar. Feedstocks are abundant and cheap, farmland biomass waste is reused, and the active group-containing active agent is added in biomass charring, which can effectively inhibit side reactions and coordinate with the catalyst to perform solid solution charring on the biomass, thereby improving a biochar conversion rate and making the charring process clean and environmentally friendly.
