Abstract: The present disclosure discloses a lance, including a lance head having: a first tube; a second tube, in which the first tube is fitted over the second one; and a through hole tube, in which the through-hole tube has a plurality of axial through holes, a second channel is defined by the first tube, the second tube and the through hole tube, and a first channel is defined by an inner cavity of the second tube and the plurality of axial through holes; an air inlet tube in fluid communication with the second channel; and an air inlet seat connecting with the second tube and having an air inlet channel which is in fluid communication with the first channel. The lance according to the present disclosure can spray uniform gas and can reduce energy consumption. The present disclosure also discloses a multi-fluid lance device equipped with the lance.

Abstract: A catalyst for producing higher carbon number hydrocarbons, e.g., benzene from low carbon number hydrocarbons such as methane has been developed. The catalyst comprises a porous support such as ZSM-5 which has dispersed thereon rhenium and a promoter metal such as iron, cobalt, vanadium, manganese, molybdenum, tungsten and mixtures thereof. A process for preparing the catalyst and a process for converting low carbon number aliphatic hydrocarbons to higher number hydrocarbons in the presence of CO or CO2 at conversion conditions are also described.
