The invention of the current application is a process for eliminating arsenic from a hydrocarbon feed which is at least partially liquid, including steps a and b. Step a includes bringing the hydrocarbon feed and hydrogen into contact with a first capture mass including a support and at least one metal M1 from group VIB and at least two metals M2 and M3 from group VIII. Step b includes bringing the hydrocarbon feed and hydrogen into contact with a second capture mass in the sulphide form including a support and nickel, the quantity of nickel being at least 5% by weight of NiO with respect to the total weight of the second capture mass. Step a) is either carried out before step b) or carried out simultaneously with step b).

Methods, catalysts, and corresponding catalyst precursors are provided for performing dewaxing of diesel or distillate boiling range fractions. The dewaxing methods, catalysts, and/or catalyst precursors can allow for production of diesel boiling range fuels with improved cold flow properties at desirable yields. The catalysts and/or catalyst precursors can correspond to supported base metal catalysts and/or catalyst precursors that include at least two Group 8-10 base metals supported on the catalyst, such as a catalyst/catalyst precursor including both Ni and Co as supported metals along with a Group 6 metal (i.e., Mo and/or W). The support can correspond to a support including a zeolitic framework structure. The catalyst precursors can be formed, for example, by impregnating a support including a zeolitic framework structure with an impregnation solution that also includes a dispersion agent.

A catalyst for the conversion of methane to higher hydrocarbons including aromatic hydrocarbons comprises molybdenum or a compound thereof dispersed on an aluminosilicate zeolite, wherein the amount of aluminum present as aluminum molybdate in the catalyst is less than 2700 ppm by weight.

This disclosure relates to the production of xylenes from syngas, in which the syngas is converted to an aromatic product by reaction with a Fischer-Tropsch catalyst and an aromatization catalyst. The Fischer-Tropsch catalyst and aromatization catalyst may be different catalysts or combined into a single catalyst. The aromatic product is then subjected to selective alkylation with methanol and/or carbon monoxide and hydrogen to increase its p-xylene content.

This invention relates to an improved process for the selective production of N-methyl pyrrolidone (NMP) from gamma-butyrolactone and monomethyl amine preferably in aqueous form in the presence of a catalyst under comparatively milder conditions than the processes well known in the prior art of literature. The process is economically viable as it provides higher yield and selectivity for NMP which reduces the cost of separation of NMP from GBL. The catalyst shows good recyclability without significant loss in catalytic activity and no frequent regeneration is required.
