The present disclosure relates to catalyst support materials and cobalt catalyst materials including such support materials, and their uses in Fischer-Tropsch processes. In certain aspects, a catalyst support material includes alumina, silicon oxide and titanium dioxide. In other aspects, a catalyst material includes a catalyst support material as described herein, with a catalytic metal such as cobalt disposed thereon.

The invention relates to Fischer-Tropsch synthesis in a compact version. A compact reactor comprises a housing, rectangular reaction channels inside the housing, which are filled with a cobalt catalyst, synthesis gas injection nozzles in the number determined by the ratio of the number of channels to the number of synthesis gas injection nozzles, an input and output nozzle for heat transfer medium on which a pressure controller installed, and an assembly for withdrawing synthetic hydrocarbons. The cobalt catalyst is activated by passing hydrogen through it. Synthetic hydrocarbons are produced by passing synthesis gas through the reaction channels filled with the activated cobalt catalyst. The space velocity of synthesis gas is increased every 300-500 h, followed by returning to the initial process conditions. This provides a high-molecular-weight hydrocarbon output per unit mass of the reactor.

This disclosure provides compositions and methods directed to thermally stable catalyst systems, which display stable physical properties and/or stable catalytic properties after thermal pretreatment at a temperature in the range of about 600 C. to about 1000 C. The catalyst systems include metal particles which contain a stable metal and a catalytic metal deposited on a porous support. Embodiments of the disclosure include catalyst systems that can be used in high temperature applications such as the hybrid sulfur cycle. The hybrid sulfur cyclic is an elevated temperature and high acid reaction that may be conducted using concentrated sulfuric acid heated to 800 C. Embodiments of the disclosure can provide thermally stable catalysts and methods to produce thermally stable catalysts that remain active for at least 80 hours' exposure to these harsh conditions.

A new family of crystalline microporous metallophosphates designated AlPO-90 has been synthesized. These metallophosphates are represented by the empirical formula
R.sup.+.sub.rM.sub.m.sup.2+EP.sub.xSi.sub.yO.sub.z
