摘要： The present disclosure relates in its first aspect to a process of converting a stream comprising methane into chemicals, said process being remarkable in that it comprises the steps of providing a first stream (1, 5, 11) comprising methane, providing a second stream (79) which is a bromine-rich stream, putting into contact said first stream (15) with said second stream (79) to obtain a third stream (21) comprising at least unreacted methane, methyl bromide, dibromomethane, and hydrogen bromide and removing said dibromomethane from said third stream (21), to produce a dibromomethane stream (103) and a fourth stream (27) comprising unreacted methane, methyl bromide and hydrogen bromide; wherein the fourth stream (27) is converted into chemicals. In its second aspect, the present disclosure concerns an installation for carrying out the process of the first aspect.

摘要： The present invention relates to a synthesis method and synthesis reactor of high-selectivity 2-methylallyl chloride by taking isobutylene and chlorine gas as raw materials and performing a gas-phase chlorination reaction in a microchannel reactor with a cooling surface. The isobutylene and the chlorine gas are reacted in a T-shaped microchannel reactor, and the mixing speed is extremely fast. Meanwhile, the huge heat exchange area per unit volume can ensure that the reaction proceeds stably at a substantially constant temperature and has good controllability. Therefore, side reactions caused by excessive local temperature can be effectively suppressed, the reaction selectivity is high, and no coking phenomenon occurs.

摘要： The present invention relates to a method for chlorination and dehydrogenation of ethane, comprising: mixing and reacting a low-melting-point metal chloride with C2H6, such that the low-melting-point metal chloride is reduced to a liquid-state low-melting-point metal, and the C2H6 is chlorinated and dehydrogenized to give a mixed gas containing HCl, C2H6, C2H4, C2H2 and C2H3Cl. In the method, the low-melting-point metal chloride is used as a raw material for chlorination and dehydrogenation, and the low-melting-point metal produced after the reaction is used as an intermediate medium. The method has the characteristics of simple process, low cost and high yield. Moreover, some acetylene and vinyl chloride can be produced as by-products at the same time when the ethylene is produced, by controlling the ratio of ethane to the chloride as desired in production.
